At 8:14am, Big Brother wakes the housemates to tell them that they have 2 minutes to collect their essential items as they are leaving the house and they can only take what they're carrying. Outside they are confronted with stretchers and a very different environment. The sauna is now the diary room and there is even an outdoor toilet.

Big Brother asks the housemates to gather around the campfire and asks Aleisha to read a letter out loud. The housemates must survive outside all week and use only 15 buckets of water. They must eat sleep and bathe outside. There is $100,000 on the line if the housemates can accomplish this task.

There is a lot of discussion about who will crack it. Big Brother asks everyone to gather around the fire again and asks Thomas to read out the letter in the envelope. There is one barrel filled with water and a second barrel which is empty. The filled barrel may, at any time, start to drain water. Any water must be collected in shells and transferred to the second barrel. At the end of the week, the second barrel must be above a certain level for the task to be successful.

The first time it happens there is a frenzy with everyone involved. The shells are small and can't hold much water and results in the housemates forming a bit of a chain to get the water into the second drum and them biffing the shells back to the start of the line. If they're too slow, water will be wasted.

Rebecca heads into the diary room to announce that she thinks it is a great task but that she's probably going to go batty this week. Particularly when it comes to being able to escape the presence of some people in the house.

Laura is complaining about missing home during this task. Daniela mutters something which Laura gets upset at but I don't think it's that big of a deal.

Big Brother wants four housemates to volunteer for another task which will be "arduous". Rebecca, Thomas, Travis and Andrew are then asked to enter the Big Brother shop. They are about to enter a new room in the house. A room that is literally, freezing. They enter the ice cave and Rebecca reads the letter which tells them they are now ice mates. They are not allowed to tell their other housemates anything other than the conditions were cold harsh and miserable despite the fact that they have warm soup and sushi. As part of the task, they have to chip off chunks of ice and put them into the two red buckets to fill the esky's.

It doesn't take the ice mates long to fill the buckets which leaves them plenty of time to enjoy the luxuries of the ice cave. They head out with their buckets and make everything sound so difficult. When they head back inside, there is ice cream awaiting. Cold, but easy.

When they head back in next there are lollies, chocolate fondue, snickers bars and an air hockey table. Outside, everyone is feeling sorry for the ice people. Inside, they're having a blast. Rebecca beats Travis and does a dance before he shows his butt in response.

When they head back into the ice cave again after making the other housemates feel terrible that they seem to be working so hard in such awful conditions Thomas says "So.. where were we?" Everyone laughs as it is quite funny. Travis does wonder what would happen if Big Brother turned on the cameras now for the other housemates to see.

It's about 10 degrees and everyone is complaining about the rain and the temperature and yet Thomas has his shirt off.

They're all crouching around the pool under the overhang to try and stay dry and are telling stories. Laura tells a sob story about being in a woman's refuge and how that she's never been in a relationship and about how hard it is to learn to love people.

Travis says the happiest time in his life was the day his little boy was born. He says that there is no better feeling than to know you've creating something. He tells Laura that when she has a baby, she will know what love is and that it will come natural to her when she does.

Aleisha says hers was the day she met emma.

While everyone is outside in the rain and cold, the ice mates are back inside eating marshmellows and melted chocolate. They manage to fill the chilly bins and call it a night from their "arduous task".

Emma says Zoran has been quiet the last two weeks but today he's short and gone back to being loud.

Andrew asks Emma if Daniela is her mate now. Emma says not even and adds that she's really happy about Sunday and can't wait.

Aleisha pulls Billy up on his affection and something he said about not knowing about it and that she thinks he's an imposter. I think she thinks he is leading her on.

Rebecca asks Jamie what secret he thought she would have. He answers that she is actually an exotic dancer with no morals. Jamie confides in Rebecca about the time he spent in an orphanage as a child.

All of a sudden the water call goes out and it's battlestations. Everyone is jumping to help transport the water via the shells to the second drum.
