Twenty new castaways and four returning players arrive in Samoa, ready for their own redemption story to begin. David Genat welcomes them to Australian Survivor: Redemption and divides them into two unnamed tribes of twelve.

• Reward Challenge: The players must stack heavy blocks to form a pyramid, then push it along a track. One player climbs the pyramid to retrieve a key and unlock a torch. Once the pyramid reaches the end of the track, the player with the torch races back to light the cauldron. The first tribe to finish wins reward.

The purple tribe wins reward. They become the "Bounty" tribe and receive fruits and vegetables, a hammock, a stocked firepit with flint, and a fully built shelter. As Lyndl was the player sent to retrieve the torch in the challenge, she secretly gained a clue to a potential advantage. The green tribe becomes the "Barren" tribe and receives absolutely nothing to begin the game with.

At the Bounty beach, the players introduce themselves and soak in the perks of winning the first reward challenge. Harry and Simon are immediately seen as big targets, as they are the returning players on their beach, while Daniel struggles with the names of his tribemates. Lyndl reads the scroll she gained from the reward challenge, which tells her that an immunity idol is buried under the tribe flag in the middle of camp. In the middle of the night, she asks Loz for help to find the idol. Lyndl finds it, but it comes with a twist: the idol can only be used by a Barren tribe member. The Bounty idol is hidden at the same location, but at the Barren beach.

At the Barren beach, the players gather to get to know each other, but they must also begin gathering supplies and building their camp from scratch. Don decides to keep his relationship to former Australian Survivor player Mat Rogers a secret and begins to take control as the building leader. Mark and Faith form an alliance called the "Ruby Soho Alliance".

• Immunity Challenge: The tribes must maneuver three wheels up and over high poles then transport them over a ramp, under a net, and up into a tower. Finally, they must roll them down a steep ramp into three narrow gates.

The Barren tribe wins immunity with all three wheels landing in their gates, while Bounty has none. Lyndl shares her idol clue with Brooke on the Barren tribe, hoping she will switch idols with her when she finds it. Back at the Bounty camp, Lyndl throws out Richard's name, but Cameron feels that Jackson would be a good target to make a big move from the start. Elsewhere, others begins to feel that Daniel is too excited and could be a liability in the long run.

At Tribal Council, Eliza voices how thankful the tribe is to have the returning players, Harry and Simon. Daniel comes under fire for his sloppy gameplay after mistakenly saying Jackson's name while throwing out names at camp. Lottie admits that the timing has to be perfect for big moves and says this is not the time. When the votes are read, Daniel is voted out of the tribe unanimously, 11–1, leaving his jacket with Simon on his way out.

At Barren Beach, Brooke begins searching around the tribe flag for the Bounty Immunity Idol, though she struggles to find time when no one else is around. Johnson tries to gather a group of allies in Sally and Ben. Mark notices how hard Johnson is playing around camp and grows wary of him, especially after his appearance on Big Brother 2022 . Mark and Brooke finally find time to talk and agree to team up. That night, they meet under the tribe flag and begin digging for the idol together, eventually finding it. Brooke plans to try to exchange both idols with Lyndl at the next challenge.

Back at the Bounty tribe, Simon and Harry continue meeting secretly at night, planning to each take control of different areas of the tribe. Lottie begins to grow suspicious of his gameplay.

• Reward Challenge: Each tribe chooses players to face off against the other tribe. Using padded bags, players attempt to push past their opponent to ring a bell, scoring a point. The first tribe to score three points wins reward.

Barren wins reward: a trip to the Survivor Shop. There, they can choose four items to improve camp life. They send Blanche and Ben, who select flint, a fish, a tarp, and bedsheets.

• Immunity Challenge: The tribes must swim out to retrieve two heavy chests and maneuver them through a wall and onto the beach. One player climbs a tower and uses a pole to release a key to open the chests. Then, the tribe must unscramble letters to spell "Immunity" and place the word on an unsteady frame. Finally, they must knock down each letter with sandbags to win immunity.

The Bounty tribe wins immunity. As they leave, Lyndl and Brooke are unable to switch idols. Don becomes an easy target because he is too vocal around camp and difficult to live with. However, Mark and Faith have other plans, wanting to split the majority of the votes between Johnson and Sally. Cat sees Mark and Faith as major threats and wants to switch the votes onto Faith instead. She lies separately to Sally, Tez, and Brooke, telling each of them that Faith is throwing their name out. Mark senses something is wrong, and Brooke relays Cat's move to him. He knows how she played on The Traitors NZ .

At Tribal Council, Mark and Ben speak about trusting and protecting their allies. Tez asks Ben directly whether he has been throwing his name out. Cat confronts Johnson, accusing him and Ben of spreading her name. Mark and Keeley quietly step away from the group to discuss Cat going rouge, leaving the others confused. The players begin moving around in an attempt to switch the vote. When the votes are read, Cat is voted out in a 7–2–2–1 vote, with Johnson and Don receiving two votes each and Sally receiving one.

At Barren Beach, Mark feels that he is on top of his tribe and in control. Johnson goes into damage control after being left out of the Cat vote the night before and sets his sights on Mark.

Back at the Bounty tribe, Eliza and Jackson continue to grow closer and lock in a final two. While Lottie has her sights set on Harry, Harry plans to gather the numbers to blindside Lottie. Lyndl spends the morning planning to make the secret idol swap at the challenge.

• Reward Challenge: Tribes must select four tribemates to work together to swing a wrecking ball and knock over three targets, winning a round. The first tribe to win two rounds wins reward.

Bounty wins reward: coffee and donuts. The tribe is surprised with mugs that have photos from home printed on them. During the challenge, Brooke and Lyndl are able to switch their hidden immunity idols. Eliza hears Lyndl's name mentioned as a possible target. Late at night, she relays that information to Lyndl, who does not take it well.

• Immunity Challenge: The tribes must race up a tower and roll a series of barrels down a ramp, push them through a track, and roll them across a bridge. Finally, they must place them on a narrow shelf and knock them down using coconuts. The first tribe to knock down all the barrels wins immunity.

The Barren tribe wins immunity. Back at Bounty, Harry does not feel that his alliance of eight is quite ready to come together. He believes the easiest vote at the moment is Loz. Eliza is happy with that plan, as it is not her or Jackson. Lyndl grows wary of Eliza after Eliza suggests that they are both on the bottom of the tribe and she does not believe this to be true. Paula hears this and begins pushing to shift the vote from Loz to Eliza instead. Lottie starts to realize that Harry and Paula currently have too much control over the votes.

At Tribal Council, the tribe feels defeated, especially after winning reward and having all the necessities to succeed. Loz knows her name is an easy vote, as she has already received a vote before. Lottie and Cameron do not want to be seen as running the tribe and say they are simply following a plan tonight. Jackson and Eliza both feel confident about the vote and moving forward. However, when the votes are read, they are shocked as Eliza is voted out in an 8–3 vote, with Harry casting the third vote for Loz.

As the Bounty tribe returns to camp, Jackson feels alone and upset about being blindsided. Lyndl pulls him aside to let him know she was the one behind the Eliza vote. Harry tries to take Jackson under his wing. Lottie notices this and wants to target the pair of Harry and Paula, believing they have too much control.

At the Barren tribe, Don is still feeling on top of the tribe but slips up by revealing his last name. He hates keeping his brother's identity a secret, so he shares it with Mark.

• Reward Challenge: Tribes go head-to-head in a rounds of tug of war, pulling a tribemate into a throw zone. Once in the throw zone, that tribemate must attempt to land a sandbag on a high beam. The first tribe to win two rounds wins the reward.

Bounty wins reward: chocolate cake. However, the cake is divided unequally from largest to smallest, with one fewer piece than there are players. Richard selects who receives each piece, leaving Cameron without any cake. Aisha finds a clue to an advantage hidden in her cake. This leads her to a "Safety Without Power" advantage. She can save a member of the losing tribe and choose a person from the winning tribe to cast a vote in their place.

• Immunity Challenge: The tribes must dig out a giant boulder and roll it through obstacles, retrieving bags of balls along the way. They then climb a high tower and run down a ramp. Two tribemates must roll the balls up a track to knock down five targets. The first tribe to finish wins immunity.

The Barren tribe wins immunity again. Back at Bounty, Paula and Harry feel uneasy about the tribe's dynamic and attempt to orchestrate a blindside against Lyndl. In an attempt to change the vote, Lottie tells Simon that Paula is targeting him. Simon goes to Harry to confirm if he is still safe but remains on edge after their conversation. As they prepare to leave, the tribe remains split between voting for Lyndl and Paula.

At Tribal Council, Harry argues that the tribe should make the simple move. The tribe discusses who is leading the vote, believing that no one has fully stepped up yet. Jackson brings up that Lyndl claimed responsibility for the Eliza vote and says he feels played by everyone. When the votes are read, Paula is voted out in a 7–2–1 vote, with Harry and Paula voting for Lyndl and Lyndl being the sole vote for Jackson.

Returning from Tribal Council, Jackson is confused about who voted for him. Harry is upset about being blindsided and vows to burn the tribe to the ground. He knows he must appeal to Lottie to get back into good standing with his tribemates. She feels good about him at the moment, and the two agree to target Lyndl or Loz.

At Barren Beach, Don comes clean to his tribe about his relationship with Australian Survivor legend Mat Rogers. Caleb feels good about his alliance with Mark and Don but gets wind that Johnson wants to target Mark next. Mark confronts Johnson and Ben.

• Immunity Challenge: The tribes must use a sled to move sandbags over a wall and through a gate, then use those sandbags to retrieve puzzle pieces. They must use those pieces to solve a hanging puzzle. The first tribe to get it right wins immunity.

The Barren tribe wins immunity for a third time. Aisha uses her "Safety Without Power" advantage and saves Loz from the Bounty tribe, choosing Caleb from Barren to join them later at Tribal Council. Loz leaves with Barren for the evening, and Bounty is given another chance at immunity.

• Individual Immunity Challenge: Players must balance a ball on a small disc while standing on pegs. The last player standing on the pegs with their ball still balanced wins individual immunity.

Lyndl wins immunity and is safe from the vote. At the Barren camp, Caleb interrogates Loz about the Bounty tribe dynamic. Loz says that if she were voting, she would want Harry gone tonight. As the Bounty tribe gets ready for another vote, Harry and Jackson know they are in danger with both Lyndl and Loz safe. Lottie would rather go after Jackson over Harry. The tribe feels it may still be too early to get rid of Harry.

At Tribal Council, Caleb joins them from the Barren tribe. He comes in hard and chaotic voicing that Harry is far too powerful to keep in the game and pushes for the tribe to vote him out. Harry and Jackson reveal that they stole the flint and hid it in one of their bags. They propose voting out Richard so the tribe can keep the flint from walking out with one of them. Jackson goes rogue, reveals that he has the flint and throws Harry under the bus. When the votes are read, Harry is voted out in a 7–1–1 vote, with Harry voting for Richard and Caleb voting for Jackson after Lottie requested he do so in case an idol was played.

Caleb returns to the Barren beach and lets his tribe know that Harry was voted out at Tribal Council. He tries to smooth things over with the returning players on his beach after previously saying that players should be gunning for them. Elsewhere, Johnson attempts to regain Mark's trust after their confrontation the other day. Mark sees through his lies but wants to keep him calm in case they lose immunity.

At the Bounty tribe, Simon feels emotional after voting Harry out. Aisha begins to realize that Lottie was pushing a different agenda by wanting Jackson gone the previous night.

• Reward Challenge: Two members of each tribe must race to retrieve a ball in the water before the other tribe. They must then give that ball to a shooter, who attempts to hit or knock three members of the opposing tribe off their narrow beam to score a point. The first tribe to score two points wins reward.

The Bounty tribe wins reward: nachos and margaritas. The tribe finally interviews Loz after she spent time with the Barren tribe. Lottie feels let down that Aisha did not go along with her plan to get Jackson out.

The Barren tribe feels defeated, as they have not won a reward challenge in twelve days. Don believes that if he had been on the slingshot, he would have won it for them. Lyndl and Keeley begin to have a bad feeling about Tez and his relationship with Mark. They come up with a plan called "Operation Snuff the Weasel" to get him voted out.

• Immunity Challenge: Tribes must dive down to unlock a series of crates. They must transport those crates through the water, over a wall, and up a high tower on the beach. A tribe member must smash the crates, releasing the balls inside. Finally, members must use a vertical maze to guide the balls into six spots. The first tribe to finish wins immunity.

The Bounty tribe wins immunity. At the Barren camp, Mark gathers a group to secretly target Johnson. He tells Johnson that Don is throwing his name out so that Johnson will cast his vote for Don. Lyndl and Keeley want to go through with "Operation Weasel." Along with Sally, they suspect a tribe swap may be happening soon and want either Tez or Caleb out before then. When they try to bring Johnson in on the plan, he becomes a little too excited and is not fully convinced. Mark senses this plan brewing and grows cautious of the girls.

At Tribal Council, the tribe is wary of being back after not attending for eight days. Brooke plays her hidden immunity idol on herself, suspecting a tribe swap and knowing it can only be used on the Barren tribe. ^[10] When the votes are read, Johnson is voted out in a 7–4 vote, with Don receiving the four votes from Ben, Blanche, Tez, and Johnson.

Don realizes he may be in danger at the next vote since he received four votes at the previous Tribal Council. Faith and Mark discuss the girls' alliance plan to get Caleb out. Faith reassures him that they are still good.

At the Bounty tribe, Simon feels emotional after voting Harry out. Aisha begins to realize that Lottie was pushing a different agenda by wanting Jackson gone the previous night.

• Reward Challenge: Tribe members must throw a ball into a chute and race through a maze in order to catch it at the end. Once they have their ball, they must attempt to shoot it into a basket, scoring a point. The first tribe to score three points wins reward.

The Bounty tribe wins reward: meat pies. In addition to the reward, it is time for the tribe swap. Caleb, Don, Faith, Keeley, Lyndl, Mark, Richard, Sally, and Tez are the new Bounty tribe, while Aisha, Ben, Blanche, Brooke, Cameron, Jackson, Loz, Lottie, and Simon are the new Barren tribe.

At the new Barren beach, Aisha is excited to get to know Blanche, as she is on board with getting the returning players out.

Meanwhile, Mark is feeling great with the new Bounty tribe. However, Keeley continues trying to pull Sally and Faith into an alliance called "The Three Wise Women."

• Immunity Challenge: Tribes must climb over a tower, then pull open a bridge to cross. Along the way, members must untie bags of coconuts and transport them over a ramp. Finally, the tribe must raise a series of targets for them to smash with their coconuts. The first tribe to finish wins immunity.

The Barren tribe wins immunity. At Bounty, Keeley and Faith discuss the vote and believe it is better to go for Tez tonight. Mark wants to target Sally, as he thinks she is untrustworthy. However, he wants to make sure Faith still feels good and agrees to go with the Tez vote. Sally wants to make a big move and gauges whether Don would vote out Mark. Immediately after, he tells Mark, Faith, and Keeley about her plan. The target then shifts to Sally. Keeley and Faith are not fully set on this new plan as it majorly protects Mark.

At Tribal Council, Richard and Lyndl are open and ready to move forward with their new tribe. Caleb and Tez discuss their differences. As they talk, Keeley sends whispers through the tribe to possibly change the vote to Don. This comes to fruition when the votes are read, and Don is voted out in a 6–2–1 vote. Sally and Tez receive the other votes from Mark and Caleb, respectively.

Back at the Bounty beach, Keeley answers questions and reassures the tribe that Don was causing too much chaos and needed to go. Caleb and Mark are upset that they were left out of the vote and feel frustrated. Mark, Keeley, and Faith form a new alliance called "Head Office." Mark also works to build relationships with the two former Bounty players, Lyndl and Richard.

At the Barren tribe, Brooke begins searching for a new idol. Blanche talks with Aisha about her old tribemates and says she feels more comfortable with the new Barren players. Blanche follows Brooke as she searches for idols. However, Brooke manages to find a new idol right under Blanche's nose.

• Immunity Challenge: Tribes must remove a ladder from a pole and use it to climb over a series of obstacles. They must then retrieve poles from a high frame and use them to remove puzzle blocks from an overhead net. Finally, they must use those blocks to solve a word puzzle. The first tribe to finish wins immunity.

The Barren tribe wins immunity again. Back at Bounty, Lyndl and Richard discuss their positions on the new tribe. Keeley grows suspicious of Richard and his closeness with his former tribemates. She wants either Richard or Lyndl voted out. They plan to bring Caleb and Sally into the vote to make them feel comfortable, while continuing to leave Tez out of the discussion.

At Tribal Council, Tez still feels left out of the vote. Mark subtly tries to signal to him to vote for Richard. The tribe discusses the value of loyalty and its importance moving forward. When the votes are read, Lyndl is voted out in a close 3–2–2–1 vote, with Caleb, Richard and Tez each receiving the remaining votes.

Back at the Bounty beach, Tez lets Caleb know he was told to vote for him at Tribal Council. Tez knows he is at the bottom of the tribe and tries to get on the good side of the women. Faith and Keeley notice that Mark is jealous of their position with Sally.

At the Barren tribe, Aisha and some of her tribemates begin to contemplate throwing the immunity challenge to protect Richard, who is now alone on the Bounty tribe. Simon and Jackson begin to consider making a move against Aisha. They gather Ben, Brooke, and Loz to create a majority alliance called "The Beauty and the Beasts."

• Individual Immunity Challenge: Players must pair up with a member of the opposite tribe. They will hold a bar over their heads while attempting to keep a ball in a chute. If the ball drops, both players are out. The last remaining pair wins individual immunity.

Simon and Faith win immunity for their respective tribes. Back at Barren, the tribe becomes suspicious of Simon and Jackson as they hold back gossip they received from the other tribe. They begin planning whether the Tribal Council will be joint or separate. The joint Tribal Council spooks Simon from making the move against Aisha. On the Bounty beach, Mark and Faith begin to worry that Richard has too many connections on the other tribe. They are split between voting for him or Tez.

At Tribal Council, David informs both tribes that one representative from each tribe will compete in a fire-making challenge against one another, chosen by their tribe, with the winner earning safety for their entire tribe. Both tribes contemplate throwing the challenge to stay at Tribal Council. Mark and Simon are chosen, and Simon wins the fire-making challenge, sending the Barren tribe back to camp. Before leaving, Simon gives his immunity necklace to Richard.

The Bounty tribe discusses the new dynamic now that Richard is safe, and Tez pleads with Mark and Keeley to vote out Caleb. However when the votes are read, Tez is voted out of the tribe unanimously in a 6–1 vote.

At the Barren beach, Ben feels comfortable with the "Beauty and the Beasts" alliance and hopes to vote Aisha out next. Aisha and Lottie are upset with Simon because he did not throw the fire-making challenge as they wanted in order to vote out Brooke.

At the Bounty tribe, Mark and Keeley want to gather a solid group together, as Mark feels the merge is approaching. Keeley tries to get on good terms with Richard, knowing he is connected with players on the other tribe.

• Reward Challenge: One member from each tribe steps up to a covered item. After looking in the box, one player must convince or persuade the other that their item is better. They can then choose to either keep their item or switch.

Caleb wins a reward of a full breakfast, Faith wins a parma, Brooke wins a tart, Richard wins a tray of lollies, Faith later wins steak, chips, and a beer, and Keeley wins tacos and a margarita. While eating her peanut butter sandwich, Blanche finds a clue to a hidden immunity idol.

When they return to camp, Blanche begins searching for the idol but is unsuccessful. She asks Aisha for help, who ends up finding it for her. The two agree to keep it secret and use it when needed.

• Immunity Challenge: The tribes are tethered together and must navigate through a series of obstacles. Once they reach the table maze, two members must attempt to land a ball into a chute. The first tribe to finish wins immunity.

Because the Barren tribe throws the challenge, the Bounty tribe finally wins immunity. Back at the Barren camp, Aisha and Blanche gather the numbers to send Brooke home, unaware that she has an immunity idol. Meanwhile, Simon and his alliance continue making Aisha feel safe.

At Tribal Council, the tribe is excited to finally vote, as many of them have only attended a few Tribal Councils so far. The original Barren members, Brooke and Ben, feel concerned because they are in the minority. However, Brooke’s calm composure causes Cameron to reconsider voting her out.

Before the votes are read, Brooke plays her immunity idol for herself, negating three votes from Aisha, Blanche, and Cameron. Aisha is then voted out in a 3–1–1 vote with Blanche's immunity idol still in her bag. Cameron and Ben receive the remaining votes from Brooke and Lottie, respectively.

At the Barren beach, Brooke and Simon are feeling on top of the tribe after blindsiding Aisha. Lottie feels played by Simon after he left her out of the vote. She and Cameron talk with Loz to see where Simon, Ben, and Jackson stand. Simon apologizes to Lottie, and they begin to repair their alliance. Lottie wants Jackson out next.

Back at the Bounty tribe, Keeley and Faith secretly meet at night and discuss when to cut Mark. In the morning, Mark is worried and paranoid about the two of them.

• Immunity Challenge: Tribes must climb up and over a huge ramp and free puzzle pieces from a wall. Then, they must navigate obstacles and collect a Monkey's fist, using it to reveal more puzzle pieces. Finally, tribes must complete their puzzle. The first tribe to finish wins immunity.

The Barren tribe wins immunity. Back at Bounty, Mark wants to plan to put a majority of the votes on Richard to weaken Simon come the merge. He asks Caleb to put a vote on Sally in case Richard has an idol. Caleb begins to feel tired of being used as a scapegoat for all the rogue votes. "The Three Wise Women" plan to abandon the Richard plan and shift their target to Caleb.

At Tribal Council, David informs the Bounty tribe that they will not be voting to send someone home. Instead, they will vote to send three people to Redemption Beach, where those players will have to fight for their spots back in the game.

The tribe discusses what needs to happen and who needs to vote where. Caleb and Sally think it is a good time to send Mark away, which Keeley is fine with. The other votes are planned to fall on Richard and Caleb. Mark hears from Caleb that Keeley is okay with him going and whispers to her not to send him to Redemption Beach. Caleb and Richard think it would be wiser to send a weaker player like Sally, in case the challenge is very physical. When the votes are read, Sally, Caleb, and Keeley are sent to Redemption Beach in a 3–2–1 vote, with Richard casting the sole vote for Keeley.

On Redemption Beach, the trio of Caleb, Keeley, and Sally are miserable and wonder what the future holds for each of their games. Keeley finds the correct key to a box, which holds an advantage in the redemption challenge. At the Barren tribe, Mark finds a hidden immunity idol right under the noses of Faith and Richard.

At the challenge, David informs the castaways that only Caleb, Keeley, and Sally will compete. The winner will rejoin the Bounty tribe, while the other two will return to Redemption Beach until the next immunity challenge. They will then join the losing tribe, where they will attend Tribal Council but each will lose their vote.

• Redemption Challenge: Players must balance on a see-saw and attempt to stack blocks one at a time. Keeley has an advantage, only needing to stack four blocks, while Sally and Caleb must stack five. The first player to stack all their blocks wins their way back into the game.

Caleb wins the challenge and rejoins Bounty. Keeley and Sally return to Redemption Beach. At the Barren tribe, Simon wants to throw the next challenge in hopes of voting out Keeley and gaining Sally as an ally. At the Bounty tribe, Faith becomes even more annoyed with Caleb being back. Mark asks Simon to keep Keeley safe, but he is not sure if Simon will keep his word.

• Immunity Challenge: Tribes must swim out to collect coconuts into a boat and push it back to shore. They must then attempt to land the coconuts into a basket held up by a member of the opposing tribe. The last tribe holding up both baskets wins immunity.

The Barren tribe wins immunity again. Back at Bounty, the tribe scrambles as only four members will be voting. Faith wants to vote out Caleb but is worried about Sally. Keeley and Faith worry that Sally could easily be picked up by another player once the merge happens. Mark now sees Faith as drunk with power and wants to take her out.

At Tribal Council, Keeley and Sally discuss feeling like sitting ducks without votes. The tribe tries to reset and hopes to enter the merge with a clean slate. When the votes are read, there is a tie between Faith and Sally. Following the revote, Faith is voted out unanimously, 3–0.

At the Bounty beach, Keeley is shocked that Mark blindsided her by taking out Faith. She knows she must be wary of him moving forward. Before the Reward Challenge, David informs the players that Barren and Bounty are no more as the tribes have merged.

• Reward Challenge: Players must stand on a wobbly barrel and balance a spool in a track. If they either fall or drop the spool, they are out. The last player standing wins reward.

Sally wins the reward, a brand-new Mahindra Scorpio 4WD. The new "Togiola" tribe is given a proper merge feast to celebrate making it this far in the game.

Lottie and Richard attempt to rekindle their friendship. Lottie bonds with Sally and Caleb and hopes to regain some footing in the game. Caleb looks to form new alliances and shake things up, targeting Jackson. The returnees reconnect and decide to remain loyal to each other. Keeley sees herself as a lone wolf and aims to align with Simon to target Lottie.

• Immunity Challenge: Players must use a knotted rope to hold onto a heavy pole equivalent to 35% of their body weight. As time goes on, they must move further down the rope. Once a player drops their pole, they are eliminated. The last player standing wins immunity.

Brooke wins the first individual immunity challenge. Back at camp, Lottie tries to form an easy majority for the first post-merge vote. She gathers a group to split votes between Jackson and Ben. Keeley continues to sense that Lottie is too dangerous to keep in the game. She and the returnees attempt to rally votes against her, pulling in Sally, Ben, Jackson, Richard, and finally Loz. Loz and Sally question whether this is the best move for their long-term games.

At Tribal Council, some players feel comfortable moving forward, though others remains a little paranoid. Lottie and Richard discuss each player's story and how this vote will reveal where everyone stands. As the discussions continue, Cameron and Lottie grow worried about the outcome. When the votes are read, Lottie is voted out in a close 9–3–1 vote, with Ben and Jackson also receiving votes.

At the Togiola beach, Caleb is upset that he was once again left out of the vote. Blanche is in the same position and pulls Sally aside to see where her head is at. The returnees and Keeley feel on top of the new tribe. Simon, Ben, and Jackson see Mark as being in control and would like to weaken him by voting Caleb out.

• Immunity Challenge: The challenge is played in two stages. In the first stage, teams of six must maneuver a buoy along a rope, over a frame, through a twisted net tunnel, and attempt to land it on a high shelf. The first team to land all six buoys advances to the second stage. In this stage, players must build a ramp and roll balls along it to land them on a shelf. The first player to land all three balls on the shelf wins immunity.

Simon wins individual immunity. Back at camp, Mark wants to make it an easy vote by unanimously targeting Blanche and Cameron. However, Ben begins to question why there are still so many returnees in the game. He, Jackson, and Loz set their sights on Mark. Some of the other newbies agree and start to wonder how to approach Simon with the idea. Richard pulls Mark aside to give him a heads-up about the plan. Meanwhile, the other returnees and Keeley question whether this is the right time to make a move. Mark also begins to sense a shift before Tribal Council.

At Tribal Council, the tribe discusses how it may be time to start making big moves. Mark whispers to Brooke and asks who changed the vote. Brooke suggests that some players may have "big move-itis." Mark then pulls Ben aside and flashes a fake idol to gauge how he and his allies might react. The tribe begins scrambling to decide who to vote for. Mark tells his allies that he thinks Richard is a weak ally and would rather see him go.

Before the votes are read, Mark plays his real immunity idol for himself, negating seven votes from Ben, Blanche, Cameron, Jackson, Loz, Richard, and Sally. Richard is then voted out by the returnees and Keeley in a 4–1 vote and Brooke receives the lone vote from Caleb.
