When they reached the last platform, they had to swim to the last short platform. Each of the eight members had to be on or above the tallest step to win. Reward: A visit from a local bushman named Tata, who would teach the winning tribe how to improve their island life using the resources found on the island.

Winner: Bikal

Immunity

For this challenge, Survivors had to cross planks in the water and then swim from a pontoon to a bigger platform. From there they had to break tiles to get keys. They then had to unlock a crate with sand bags in them. They had to throw the bags at blocks. The first tribe to have knocked all the blocks off a big platform, which raises their tribe flag, wins. Winner: Bikal

Final Words
"gota"

- As a viewer on the couch, you only get to see one side. You don't feel the hunger, you don't feel the thirst in your mouth. It's very real. I knew coming in here my muscles weren't my biggest asset, and I used everything else I had. I think a lot of my plans were left unresolved, but good luck to the rest of them, they really got me.
