Survivor is back, and this time the 16 American contestants will be battling it out in The Australian Outback for 42 days, all vying for the grand prize of million. At the beginning of the show, the 16 are split into two tribes - Kucha and Ogakor. In the first 3 days in the Outback, Debb begins to get on the nerves of her fellow islanders with her attempts to take control, while Kimmi's over-eagerness to have fun grabs Jeff the wrong way, and Keith and Jerri clash almost immediately. When Ogakor wins the first Immunity Challenge, Kucha makes the long hike to Tribal Council where, with a 7-1 unanimous vote, Debb is voted out of the Outback. The tribe has spoken.

By Day 4, the separation from food really starts to take a toll on some of the contestants. No food is offered at the Reward Challenge, where Rodger faces his fears and jumps off a cliff only to have his tribe lose, but everyone is bound to get some nutrition with the Immunity Challenge. Unfortunately, the food supplied - cow brains, beetles, and worms - isn't what the castaways are hoping for, and Tina can't stomach it, giving Kucha, led by vegetarian Kimmi, Immunity from Tribal Council, which is exactly where Ogakor is forced to go. At the vote, Jerri's suspicions that Kel has been eating a secret stash of beef jerky seems to be enough to get him kicked off, as Kel becomes the second Outback competitor to get his torch snuffed.

Mike becomes obsessed in hunting for a pig for his tribe but Jeff thinks that Mike's an idiot. At the Reward Challenge, Ogakor won by wining Fish Bait. Jerri, Amber & Mitchell went fishing and ended up catching fish for their tribe. At Kucha, everyone begins calling Rodger "Kentucky Joe". Rodger finds a heart shaped stone and gives it to Elisabeth so she can give it to her boyfriend back home. Jeff & Alicia make an alliance and add that Nick should not feel safe and that he's way too confident. Back at Ogakor, Jerri & Colby continue to get closer when Jerri spends the day massaging Colby's back. Keith becomes suspicious by there attraction and says he would vote out Colby. At Immunity, Maralyn keeps falling down which helps Kucha wins there 2nd straight Immunity. Keith asked Tina & Colby to vote with him to vote out Mitchell. At Tribal Council, Mitchell receives 1 vote, Jerri receives 1 vote, and Maralyn receives 5 votes and is voted out.

Keith & Tina begin the day trying to go fishing until Jerri takes the boat instead. This frustrates Keith because he wanted to strategize with Tina. Both Tina & Keith begin to feel in trouble because of Jerri's comments last night that she felt close with Amber, Mitchell & Colby. At Reward, Kucha pulls off the victory. A forest fire is creeping closer to Ogakor camp as the survivors get worried. Tina admits to both Colby & Mitchell that she feels Jerri is bossy. Kimmi gets mad when everyone expresses they want some meat. Jerri joins Colby in his pig hunting to try and win his allegiance. Mike finally catches a pig and everyone enjoys a great lunch. At Immunity, Kucha pulls off another victory. At Tribal Council, we have our first tie between Mitchell & Keith. Because Mitchell has more votes from previous tribal councils, he is voted out.

Jerri wakes up to find smoke covering camp from the fire, but has other things on her mind - just recently she has realized that Colby has an alliance with Tina & Keith. Jerri talks with Amber and tells her the importance in getting Colby back on their side. At Kucha camp, Kimmi becomes more and more depressed because no one respects that she's a vegetarian. She and Alicia get into a fight over the chickens and begin shouting. Later, Kucha wins the reward challenge, getting soaps and shampoos, and the other tribe members bathe a reluctant Kimmi in the dirty river water. At the Immunity Challenge, Ogakor breaks their losing streak, sending Kucha to Tribal Council, where Kimmi receives six votes and is voted out of the game. The tribe has spoken.

Things seem to be looking up for Kucha - their winning streak looks to be restarting, as they steal the Reward Challenge from right under Ogakor's noses, and they create a new kind of food: Kucha corn, made by heating up chicken feed. But the same fire that cheers the Kucha tribe up turns suddenly volatile when tribe "leader" Michael passes out from smoke inhalation, and falls face-first into the camp fire. Mike is flown away to a hospital via helicopter, leaving his tribemates behind. Meanwhile, the Ogakor tribe, given the bittersweet gift of Mike's elimination, worry about what has happened when they receive treemail announcing the accident. Next week the tribes will merge on equal ground - who will come out prosperous?

Kucha and Ogakor receive tree mail at their camps - the tribes are merging, and as a pre-merge twist, the women are all meeting together at Ogakor camp and the men are all converging at Kucha camp. With everyone ready to move full-time into the Kucha territory, all are surprised to learn that they will be living in a new section of the Outback, and that they will have to create a new shelter, and adapt to their new surroundings. Despite some merging festivities, where the castaways become Barramundi and receive a big picnic basket full of elaborate platters, the tribal lines run deep as former tribemates strategize the best way to pick off each member of the opposing tribe. The Immunity challenge lures Keith into a strong sense of safety when he withstands an endurance competition longer than anyone else, who all settle for temptations. At Tribal Council, it comes down to a nail-biting tie between Jeff and Colby - but Jeff, who has already received at least one vote in a previous tribal council, is sent home, just missing a spot on the jury.

Desperate to keep her tribe alive, Elisabeth begins to think that she can possibly lure Tina to vote for Jerri, the perfect person to target, because of her annoyance-level at camp. At the Reward Challenge, everyone gets some time off from Jerri and her pocket pet when Jerri wins a boomerang throw and decides to take Amber with her for a feast. Later, Jerri and Amber share their suspicions that Keith and Tina may be thinking about going against the former Ogakor members, and at the Immunity Challenge, Jerri loses her chance to vote out Keith when he wins Immunity for the second time in a row. At Tribal Council, Elisabeth's plan to get rid of Jerri fails to work when one of her own comrades, Alicia, is voted out of the Barramundi Tribe.

A look back at the first 24 days of "Survivor: The Australian Outback" including never-before-seen footage.

Jerri and Colby win a reward challenge, where they are sent to spend the afternoon on the Great Barrier Reef. What turns out to be a surprise for Jerri is that Colby brought back pieces of coral for everyone. In a bigger surprise, Jerri finds herself going home when Keith, Colby, and Tina team with the Kuchas to vote her out.

As the days grow longer and the temperature increases, the energy-less Barramundi Tribe quickly shifts into survival mode, trying to find a way to get food, since they only have one cup of rice left. At the Reward Challenge, everyone is treated to some food during a Survivor Acution, but it doesn't last long, and it does not give the tribe energy enough to sustain themselves. It's obvious how tired the players are during the strenuos Immunity Challenge, which Colby wins, and later, Jeff Probst makes a deal with the castaways to trade all of their tarps for more rice to last the final thirteen days in the Outback. The survivors make the trade, but how will they cope without shelter? The issue is put on the back burner as the Ogakor alliance votes off Nick, making him the third member of the jury.

The remaining 6 survivors compete in a reward challenge which sees Colby winning yet again. Colby for his reward gets to ride on a horse and have a shower while he has a feast. The 5 others return home to find their shelter destroyed by a flash flood. Rodger worries when he can't find the tin of rice. Tina & Keith hike down the river to find the rice and swim in the water to retrieve the tin of rice. Colby wakes up and has eggs and bacon as part of his reward. Colby is shocked when he returns to camp to find it destroyed by the flood. The survivors work together to re-build their shelter. At the immunity challenge Colby yet again wins. At Tribal Council, Rodger receives 2 votes while Amber receives 4 votes and becomes the 4th Jury Member.

The remaining 5 survivors (Colby, Tina, Elisabeth, Rodger & Keith) are beginning to get homesick. Tina explains how she misses her husband and her children. Elisabeth states that she misses her mother. The survivors at the reward challenge get to email their loved ones. Keith surprises his girlfriend by proposing to her; she says yes. Tina's husband wins the challenge and gets to talk to Tina for a while. The survivors decide to play a friendly game of frisbee. Keith & Colby get into a huge fight over rice portions. At Immunity, Colby yet again wins. At Tribal Council, Keith receives 2 votes while Rodger receives 3 and becomes the 5th Jury Member.

It's day 37 in the Outback, and only four contestants remain. With Rodger gone, Elisabeth is the only member of the original Kucha tribe remaining, and is pulling out all the stops to get herself in to the final two, as she believes she will win if she makes it that far. The Reward Challenge consists of many elements of previous challenges, and ends with Colby winning a car and a visit from his mother. The Survivors learn that, between them, they have lost 85 pounds during the last five weeks, and when Colby wins the Immunity Challenge as well, he must make a difficult decision as he contemplates voting off Keith, "the least deserving." As the contestants receive care packages from home, one of them is going home and, with a unanimous 3-1 vote at Tribal Council, Elisabeth Filarski, the last remaining Kuchan, is voted out of Barramundi. Only Colby, Keith and Tina remain. Who will win?

It's the last three days in the Outback, and only Keith, Tina and Colby remain. They are set a challenge to carve totem poles to "give back to the land," causing Colby to enter a reflective mood. On the penultimate day, they toss their totem poles in to a waterfall as an act of respect and then take part in their final Immunity Challenge, a question-and-answer round about their departed tribemates. Colby wins Immunity, and casts the single vote that gets rid of Keith, and places him and Tina in the final two. After they dismantle camp and look down on the Outback from the highest peak they can find, the final two Survivors head to their final Tribal Council, where after their speeches and quizzing from seven former members of Barramundi, the Jury cast their votes. We then cut to a live show from Los Angeles, where host Jeff Probst reveals the results of the Jury vote live. In a 4-3 vote, Tina Wesson, the 40-year-old Nurse from Knoxville, Tennessee, walks away with million and the title of Ultimate Survivor.

The 16 contestants reunite to discuss their experiences in the Outback. Bryant Gumbel is the host.

This episode follows the life of each Survivor 2 member after they came back from the Outback.
