Pictures circulating on the internet appear to show two men sexually assaulting a female housemate, understood to be 22-year-old student 'Camilla', of Victoria.
One of the pictures, on a US website, appears to show housemate Mr Bric lying next to the woman with his arm over her.
A second photo appears to show a male housemate topless and kneeling on the bed with his crotch in her face.
His back is to the camera, but his hand is positioned at the front of his pants at his crotch.
In a joint statement made shortly after they were escorted from the house, the pair said: 'We had a great time in the house. It is unfortunate it had to end this way, but Big Brother has rules and regulations and we broke them.
'We are all very close in the house and we would never do anything to offend our fellow housemates.'
But while discussion of the incident has been banned on the official Big Brother website, at an unofficial site, people were scathing.
One person who posted to the unofficial site said the incident allegedly occurred when Mr Cox slapped the female on the face with his penis, a practice described on the site as 'turkey-slapping'.
'One guy holding a girl down while the other slaps her in the face with his dick is not offensive?' said one poster.
'Geez this show is sick. No wonder I am bored with it and never tune in,' said another.
