Big Brother Australia 13 is the current thirteenth season of the Australian version of Big Brother.

Background

The House

Last's seasons house was used once again. However, Channel 7 revealed that the next season of the show would move to a brand new house. Compared to last season, the house had very few differences. The "Green Room" was replaced by the new "Cave Room" and the house had a new area specifically for the nomination competitions.

House Photos

The house was revealed on April 22, 2021. All of the rooms were given a new and revamped style, but ultimately had the same layout.

Task History

Big Brother Australia 13 Task History
Week Day(s) Task Description Result
1 1 After the first three housemates entered the house, Big Brother requested that one of them enter the Diary Room. Daniel, who entered it, was given a secret mission to sneak out of the house undetected, with Big Brother providing him with an escape plan. He was also allowed to bring one housemate with him. If he successfully completes the task, he and the housemate that he brings would earn immunity from the first eviction. Yes!.png
4 On Day 4, Melissa was given a secret mission to hide a lamb figurine in each of the rooms of the house. She was allowed to recruit one housemate to help her. If any of lambs are found, Melissa would fail the secret mission. If she succeeds, the house would earn a lamb roast dinner. Yes!.png
6 On Day 6, Big Brother placed thousands of balloons in the house. Inside of eighteen of them were golden cinema tickets. If the housemates find a balloon with a ticket, Big Brother would award them a movie night. Yes!.png
2 9 On Day 9, the housemates had to participate in "Scary-Oke." Each housemate had to enter the Scary-Oke room one at a time and sing "Walking on Sunshine." Additionally, the housemates had to stick their bodies into a dark box with a creature or an object inside. If all of the housemates succeeded, the house would earn an espresso machine. However, if one housemate failed, the whole house would fail the task. No!.png
11 On Day 11, Big Brother attempted to surprise the housemates by "throwing surprises" at them. Their goal was not to react to these surprises. If the housemates complete the task, they would earn a KFC feast. Yes!.png
14-15 On Day 14, the housemates competed in a 24-hour shopping task. Big Brother added a faulty alarm system throughout the house. For the next 24 hours, the housemates had to deactivate the alarms when they rang. If they successfully deactivate the alarm in a certain amount of time, they would earn $10 for their weekly budget. $220

1 2 On Day 2, the housemates had to climb a 7-meter tower to collect six bags of wooden blocks. They would have to jump off of the tower to retrieve the bags. After collecting all six bags, the housemates would have to vertically stack all seventeen blocks so that they would all be able to balance. The first housemate to do so would become the first nominator of the season. Australia13 Small Renata.jpg
