Season logo for prospective "House of Love" theme

Although the season was initially intended to have a "House of Love" theme, the format was later scrapped. Channel 7 later announced that the show would be changed to a "more stripped-back, traditional Big Brother" with a younger cast.[1]

Task History[]

Week Day(s) Task Description Result
1 2 On Day 2, after the breakdown of the BB Express, Big Brother gave the housemates in the main house the ability to bring the 4 separated contestants into the game by responding to steamy questions. If their responses generate enough steam, the BB express would be able to return to the house and the housemates would all receive a party. Yes!
4 On Day 4, for their first shopping task, the housemates, competing in pairs, had to answer questions about their partner. If they successfully answer a question right, they would earn $10 for their budget. However, if they answer a question incorrectly or take too long to answer, they would be electrically zapped. $350
8 On Day 8, for their shopping task, the housemates had to "show the love" in Big Brother's kiss cam task. Every time a sound is played, the two selected housemates must show physical affection for each other. If they can successfully do so, they would earn an additional $10 for their shopping budget. $310
8-10 On Day 8, Big Brother gave Dion a secret mission to save one housemate from the upcoming mission. However, in order to save them, he must bring one of the nominees to a hidden door behind the pantry. If he does so without getting caught, both him and the chosen nominee will be saved from eviction. However, if he gets caught, he would also be added to the nomination list. Yes!
2 10 On Day 10, after removing food and water from the house, Big Brother gave the housemates the task to remain positive throughout the whole day. If they can successfully do so, they would be provided with a reward. However, if they fail, the entire house would be be indefinitely conjoined together in pairs. No!
14 On Day 14, housemates were individually called into Big Brother's library. Every time they make a loud noise, $40 would be deducted from the initial $1,000 budget. The remaining money after all contestants go to the library would be the house's shopping budget for the week. $80
3 17 On Day 17, Big Brother gave Graciemae and Lewis a secret mission to hide mini Cupid figures throughout the house. They would be given instructions on where to place them via text message. If they successfully hide all of the figures without getting caught by their fellow housemates, they would become the King and Queen of the house. However, if they fail to do so, they would be banned from becoming King and Queen for the rest of the season. Yes!
18 On Day 18, the housemates were told that they were rigged to a lie detector test. They would be grilled with questions about the game and told if they were lying or not. However, unbeknownst to the housemates, Graciemae and MineƩ were determining the results of the test. If the contestants "told the truth" more than they "lied," then the house would earn an Asian banquet. Yes!

1 3 On Day 3, the four final housemates to enter the house, Annelise, Lewis, Louis, and Luke, had to spin a disc to release a bag of balls. Afterwards, they had to slip on a mat to retrieve a ball. Then, they needed to land twelve balls into a goal. The first housemate to do so would earn the power to nominate three housemates for eviction. Australia15 Small Luke

7 On Day 7, the housemates, competing in pairs, had to carry water balloons with their mouths across a bar. They would then have to burst their balloon above a grate. Once their grate was full, they would have to retrieve a ball from inside the tube. The first pair to do so would have the power to nominate three housemates for eviction.

2 12 On Day 12, the housemates had to hold a weighted ball above their head along with suspending their feet mid-air.

3 17 On Day 17, the housemates, competing in pairs, had to navigate through a maze, attempting to place three balls on a suspended disk. One of the contestants was blindfolded while the other was trying to guide them. The first pair to successfully place three balls on the disk would earn the power to nominate three housemates for eviction. Because Teejay was not selected to compete in the challenge, he was immune from eviction. Australia15 Small JoshAustralia15 Small Sisters

21 On Day 21, the housemates, grouped in pairs, had to draw portraits of each other while being electrocuted. The pair that draws the best drawings of each other would earn a special dinner from Big Brother, while all of the losing contestants would be indefinitely confined to one another.

24 On Day 24, the housemates had to maneuver three puzzled poles to release a ball. Then, they had to balance these balls through one end of a maze to another. After completing this, they had to dig themselves through a sand tunnel, where after crawling through, they would find a puzzle to solve, which when solved would reveal three numbers. These numbers would be used to unlock a barrel containing six balls in total. Finally, they must throw these balls into a Big Brother eye, moving them into slots. The first housemate to do so would have the power to determine the last evictee of the season. Australia15 Small Louis
