Big Brother (Australian season 7)

On 29 January 2007, Network Ten, Endemol Southern Star, and Masterfoods announced "Australia's biggest ever integrated television promotion", the Big Brother Starburst Golden Key, which would allow a member of the public to enter the Big Brother House as a housemate.[6] Unique alphanumeric codes were included in packs of Starburst, a confectionery manufactured by Masterfoods. One hundred codes gave the opportunity to audition for the BB season after it began. Of these people, one would become a housemate and be eligible to win the season and all prizes.[6] The winner of this competition was selected during a special episode called "Golden Key". On Day 18, Nick Sady was announced the "Golden Key" winner and entered the Big Brother House.[7]

Big Brother originally informed the housemates that there was zero prize money.[8] Later they were informed that they could earn prize money by completing various tasks (similar to that of The Mole).

This year the winner of Friday Night Live was given a greater power in nominations. Replacing the Three Point Twist of previous seasons, the Friday Night Live winner each week this season was required to choose one nominated housemate to be removed from the nomination line-up, and to nominate another to replace them.[9] The winner of Friday Night Live this season was also given the chance to discuss their nominations, both past and present, with their chosen housemate whilst inside the Rewards Room.

All staple foods provided to housemates this year were vegan. The housemates could supplement this with milk and eggs supplied from the farm yard and herbs and mushrooms from the herb garden.[10]

For the first time Big Brother Australia featured a telephone in the house. It was situated in the lounge and was shown on the Opening Night broadcast before the housemates entered the house. On Day 37, Big Brother informed housemates that if the phone rang only one housemate could answer it. Joel was nominated to answer it on the housemates' behalf. On Day 52 Joel received a call from Big Brother advising that he would be away from the house and would communicate via the phone to Joel at various times.[11] On Day 58 Andrew picked up the phone as a joke, and was penalised by being sent to the Punishment Room to polish boots. Michelle joined him in the Punishment Room due to the weekly task which involved housemates remaining partnered. On Day 97 the housemates were allowed to speak with several of the Big Brother UK housemates.[12] The UK Big Brother House also had a telephone and unlike the Australian version this was the first time the phone was used in the UK version.

Adjacent to the kitchen was a new room called the "Chill Out Room". As an official rule, no more than three housemates were allowed in the room at a time. It provided a quiet place to talk or relax, away from the rest of the housemates.

On 23 April 2007, the four remaining wild-card housemates not selected to enter the House via the public vote on Days 1 and 2 were isolated in the "White Room". The housemates were Cruz, Demet, Kara, and Harrison. The White Room and its fixtures and fittings were all entirely white, and the housemates had only white clothes to wear. White Room housemates were provided with a white porridge which fulfilled all nutritional needs.[13] In the centre of the room was a red button. At any time, a housemate could press the red button if they wished to leave. This decision to leave was final and the quitting housemate could not return to the Big Brother House or the White Room. The challenge was that the housemate who stayed in the White Room the longest without pressing the red button would become a legitimate Big Brother housemate and enter the main house with the rest of the housemates. Monitors in the Big Brother House allowed the housemates to watch, without audio, the White Room housemates at all times. The White Room housemates were unaware that they were being watched by the Big Brother housemates. Cruz was the first white room resident evicted when he pressed the red button after Big Brother offered $750 to whoever pushed the red button first.[14] In the days after Cruz departed no one else volunteered to leave, so Big Brother ran a set of challenges to decide who from the White Room would move to the main house. First, Kara was evicted when Harrison and Demet nominated her.[15] Then, the Big Brother housemates lodged their votes on who they wanted in the house.[16] Demet won the vote and became an official housemate.[17]

• Demet: Aleisha, Andrew, Emma, Hayley, Jamie, Joel, Kate, Rebecca
• Harrison: Bodie, Susannah, TJ, Thomas, Travis, Zoran

It was revealed on the Game On episode that housemates Hayley and Andrew were secretly in a relationship. Big Brother set the task to both housemates to enter the house and keep their relationship secret for one week. If successful in this task both would be allowed stay in the house; if they failed then one of them would be evicted. All other housemates had individually been challenged by Big Brother to secretly discover who was in a secret relationship, each believing they were the only housemate to be issued this challenge. Housemate Billy was added on Day 2. Billy is Hayley's former boyfriend and was added specifically to complicate her task of keeping her relationship with Andrew secret. Hayley was not allowed to inform anyone, including Andrew, of Billy's true status. Each day he received a mission from Big Brother to put pressure on Hayley's secret challenge.

1. Day 2: Before Billy went to bed, he had to say "Goodnight Hayley, sweet dreams".
2. Day 3: From the moment Hayley woke up, Billy had to "wait on her hand and foot" and become her best friend. He also had to pick a bunch of flowers from the garden and give them to Hayley, and ask her to help pick the herbs.
3. Day 4: When Billy was asked to take a housemate with him to tend the animals, he had to choose Hayley.
4. Day 5: Billy had to become Andrew's best friend.

Big Brother confirmed on Day 8 that Billy's mission was an overall success, and his reward was becoming an official Big Brother 2007 housemate (who could compete to win Big Brother Australia 2007) on Day 16. On 29 April episode, Big Brother revealed the secret relationship. Three housemates had correctly guessed Hayley and Billy were involved. As fewer than half of the housemates had guessed correctly, Big Brother deemed Hayley and Andrew as successful in their challenge so both were allowed to stay. Big Brother also revealed that as Hayley and Andrew had completed their task successfully $50,000 had been awarded into the prize pool.

Housemates this season were not featured as guests on variety/talk show Rove. Previously housemates would appear on Rove in the days following their eviction. As of 2007 Rove aired on Sunday nights at 8:30, immediately after the Big Brother eviction show. As Rove is taped in Melbourne, Victoria it was impossible for the housemates to travel so quickly to appear on both shows[18] (it is normally a two-to-three-hour flight from the Gold Coast to Melbourne). Even so, Rove chose not to cross to evicted contestants following the eviction shows, as Rove would not start airing immediately after Big Brother.

The public were able to submit nomination votes via SMS for 2 July nominations. The housemate with the most votes received two nomination points, and the next housemate received one point. With the tally counted, Michelle had the most votes from the public and so received an extra two nomination points. Daniela received an extra nomination point. As winner of Friday Night Games Daniela had the power of saving one housemate from eviction. She saved herself.

Big Brother changed the usual format for Week 12 nominations. For this week viewers could nominate housemates, and from the nominated housemates the housemates themselves could vote to evict, reversing the usual procedure. While housemates were put through the usual nomination procedure and their nominations were screened, unknown to them, their nominations were ignored. Viewer nomination points were counted. On Sunday's eviction the housemates were apprised of this twist, and then were individually be asked to nominate to evict any of the nominated housemates. The nominated housemate with the most votes was to be evicted.[19][20] Daniela was evicted with a total of 12 points.

"Game On" was a live show that was broadcast on Day 2 (23 April 2007). The results of the overnight wild-card SMS vote were revealed. Susannah and Zoran were the chosen two out of the six wild-card housemates. The remainder of the wild-card housemates were isolated in the White Room. The Daily Show was incorporated into the first part of the live show. Hosted by Gretel Killeen.

"Full House" was a live show that was broadcast on Day 8 (29 April 2007). It was aired in the timeslot usually occupied by Eviction shows. The relationship between Andrew and Hayley was revealed to the house, as was Billy's role to impede Hayley's task of keeping that relationship secret from the other housemates. Hayley and Andrew were deemed by Big Brother to have successfully kept their relationship a secret from the housemates for the week (fewer than half of the housemates had successfully guessed their relationship) which meant they could both stay in the house. Big Brother also revealed that for succeeding in their task they had earned $50,000 to be added to the prize money, which was previously set at zero. Big Brother also tempted the wildcard housemates to leave the White Room by offering a sum of money to them (A$750), which Cruz accepted. Hosted by Gretel Killeen.

"Wild Card Entry" was a live show broadcast on Day 11 (2 May 2007). The White Room housemates had left the room and, dependent on their success completing various challenges, one of them would enter the Big Brother house as a housemate.

• The first round was determined by nominations from the White Room housemates; Kara was eliminated with two votes.
• In the second round each housemate had to collect three major items of clothing and dress a model while airborne on a large steel frame.
• The third round was determined by nominations from the Big Brother housemates. To cast their vote they placed a plastic ball into the corresponding tube for either Harrison or Demet. Demet won with 8 votes against 6.

Hosted by Gretel Killeen.

"Golden Key" was a live show broadcast on Day 18 (9 May 2007). This special was to select the winner of the Starburst Golden Key. The show's producers had selected five finalists from the original 100 Golden Key winners after an intensive audition process. The chosen finalists were Carolyn, Nick, Natalie, Angie and Laura. To select which would become a housemate contestants chose one of five numbered discs randomly from a bag. Then they were allocated a clear box of confectionery depending on which disc they had selected. One box also contained a golden key, and the contestant whose box contained the key, Nick, was designated the new housemate. He entered the house during the show, while the housemates were conducting their weekly task performance. Hosted by Gretel Killeen.

The 6th Live Eviction show was a 90-minute eviction and intruder special that aired on Day 50 (10 June 2007). It featured a double eviction and introduced the two new intruders, Michelle and Zach.

Hosted by Gretel Killeen.

The season finale aired on Day 100 (30 July 2007) in which Aleisha was announced the winner and Zach the runner-up. It was the closest winning margin in Australian Big Brother history of less than 500 votes and the announcement of the winner was delayed by an hour after the voting lines closed as votes were rechecked.[37] At one point during the final episode, there was just 64 votes difference between the last two housemates.[37] Aleisha is the second female to win Big Brother Australia.
