Nominations
A fundamental and strongly-enforced rule of Big Brother Australia is that nominations, and the use of the Twist, are not to be discussed at all. Specifically, all housemates are forbidden from disclosing to other housemates who they have previously nominated, who they plan to nominate in the future, or who their Twist has been used on; and they must not engage in conjecture about who may attract nomination votes and why. These discussions are banned and are deemed collusion by Big Brother, as they may give housemates a competitive advantage. Breaking this rule incurs fines, punishment, or loss of the right to nominate in the following round.
During the 2007 series the winner of Friday Night Games and their chosen companion in the rewards room were permitted to privately discuss who they plan to nominate, whilst in the rewards room.
2008 introduced a nominations room where housemates were allowed to discus who they wanted to nominate; this appeared halfway through the season.
In Big Brother 2012, the housemates are allowed to nominate a total of 5 points, but cannot nominate no more or less house mates than 2. So, that means, one housemate can give another housemate 3 points and then another housemate 2 points or a housemate 4 points and then 1 point.
