Big Brother Australia 2005, also known as Big Brother 5, was the fifth season of the Australian reality television seriesBig Brother, and was aired on Network Ten in Australia, and TV-2 in New Zealand with a four-week delay. The series started on 8 May 2005, with housemates going into the House the day before, and finished on 15 August 2005, lasting 101 days. The theme for this season was "single, sexy, and competitive". Auditions for housemates were held in March 2005. In a departure from usual procedure, candidates were not required to send in videos of themselves as had been the case for prior auditions. Instead, the producers toured major Australian cities and conducted interviews. They searched for sexy singles that were willing to have sexual relations on camera. Promos for the show suggested that Big Brother would be different this year, and phrases such as "Assume Nothing, Expect Anything", "Let's Play", and "Think Again" were used throughout the series, especially during Opening Night. The winner announced on the finale that was watched by 2.282 million Australian viewers.
Changes and additions
Fines
On Opening Night, it was revealed that $5,000 Australian dollars would be subtracted from the $1,000,000 prize money every time the housemates broke a rule. Such rules included discussing nominations, which must remain secret, not giving adequate reasons for nominating, and forgetting to wear microphones at all times. Michelle was known for being the housemate to get the most such fines - $65,000. Geneva had the least amount of fines $15,000, two in the early days at the house and one near the end of her eviction.
The Logans
It was revealed that twins would be entering the House, regularly changing places without the other housemates knowing - this was a twist first used on the fifth American series of Big Brother. [|Greg] and [|David] entered the House as a single person named Logan. Their task was to remain undetected for two weeks while swapping places at Big Brother's command. The secret of the twins was discovered one week into the series by housemate Glenn, and this was revealed during Lies Exposed. As a result, both Logans were able to continue living in the House, but would be treated as a single person in matters such as evictions and nominations. Late in the series a special eviction was held where one twin was evicted based on the votes of the other housemates, and the remaining twin allowed to continue in the House as a normal housemate. During this eviction process, David was evicted. However, because Greg was the last housemate to be evicted, both David and Greg shared the prize equally.
On Day 0, each housemate was called to the diary room and asked to pick another housemate to not receive their suitcase for the duration of their time in the house. Constance had the majority and lost her suitcase. The voting went as follows:

Weekly summary and highlights
Special shows
Live Surprise
"Live Surprise" was a live show broadcast on Day 2. During this show, the Logan twins swapped places with each other for the first time. They were given two minutes in the Diary Room to exchange as much information as possible, and Greg then had to go to the Isolation Room while David went into the Big Brother House. The Daily Show was broadcast as a part of Live Surprise. Hosted by Gretel Killeen.
Lies Exposed
"Lies Exposed" was a show broadcast on Day 8. After Glenn's discovery that Logan was in fact two twins, this was revealed to all of the housemates. Before this, Constance, Dean, and Nelson were all evicted to the Punishment Room; and were told their fate by Big Brother. Hosted by Gretel Killeen.
Viewers Verdict
"Viewers Verdict" was a live show broadcast on Day 10. This special was aired because Constance, Dean, and Nelson, had all lied about their relationship status. A public vote was held, that was started on Day 9 and was closed during the show, minutes before two of these housemates who had broken the rules were evicted. Constance and Nelson were evicted in this show, and were reunited with their partners. They both had separate eviction interviews with Gretel, and were both told that because they had deceived Big Brother, they would receive no prizes. Dean was safe, but Big Brother still punished him by banning from nominations and by putting him up for the public vote next week.
Housemates: Incoming!
"Housemates: Incoming!" was a live show broadcast during Day 25, where replacement housemates Rachael and Vesna were introduced to the public and put in the House.
"Intruders Arrive" was a live show broadcast on Day 53, where Intruders Heath, Rita, and Melanie entered the Big Brother House.
Intruder Eviction
"Intruder Eviction" was a live show broadcast on Day 59. The housemates were given 1 minute 30 seconds to discuss amongst themselves which of the new Intruders, Heath, Melanie, and Rita, they wanted to keep. They decided to keep Rita, so Heath and Melanie were put up for eviction. As the public SMS vote started and finished during the show, lasting only twenty minutes, viewers in Western Australia, South Australia, and the Northern Territory were not able to vote as television shows in Australia are broadcast with a delay depending on the state to compensate for differences in Australian time zones. Heath received the most votes and was evicted. Hosted by Gretel Killeen.
