Prime Minister John Howard has urged the Ten Network to cancel the controversial reality television show Big Brother.
Family groups and politicians have again called for the show to be axed after two housemates were thrown off the show for sexual misconduct.
Mr Howard said it was a matter of taste and called on the network to self-regulate.
"I think it is just a question of good taste," Mr Howard told Macquarie Radio.
"I don't like heavy-handed regulation. The business community is always saying to me 'let us self-regulate'.
"Well here's a great opportunity for Channel 10 to do a bit of self-regulation and get this stupid program off the air."
Communications Minister Helen Coonan said she had asked the Australian Communications and Media Authority (ACMA) to determine whether any code of conduct had been breached.
"I have spoken with the chairman of ACMA this morning and he will be providing an urgent assessment about possible breaches of codes of conduct relating to television content," she said.
A Queensland police spokeswoman said they had received no formal complaint about the incident.
"The producers of the program contacted police late (Sunday) morning inviting them to view a video of an incident involving the three contestants," she said.
"Following that viewing and, after speaking to the three Big Brother participants and producers, police say at this stage there is insufficient evidence for any criminal investigation."
Family First senator Steve Fielding has also been a vocal critic of the show and wants it axed.
"How many more warnings before action is taken? How many more sleazy incidents do we need before this show is evicted?"
Federal Opposition Leader Kim Beazley also joined the issue.
"If my advice is worth anything to the folk who run Channel 10, and how they choose to conduct themselves is their business, I'd say `make this Big Brother the last'," he told journalists.
Secretary of the Victorian Family Council Bill Muehlenberg said the show should be axed immediately in the wake of the incident but he believed some at Network Ten would be "rubbing their hands in glee" at the publicity it would generate.
"We have been calling it Big Brothel all along. Brothels are concerned about sex and money, and so are they," he said.
Australian Democrats senator Andrew Bartlett says Big Brother should be left alone by meddling politicians.
"It is politicians trying to be Big Brother that we really need to be concerned about," Senator Bartlett said.
"If anyone in the Big Brother house broke the law, then it can be dealt with by the legal system," he said.
"Attempting to force a television show off the air because of an incident that wasn't even screened on television is an excessive intrusion into the lives of Australians by moralising, preaching politicians who want to control how people live their lives."
Security guards escorted "Ashley", a pseudonym for 20-year-old Michael Cox, of Perth, and 21-year-old "John", whose real name is Michael Bric, of Melbourne, from the Big Brother house on the Gold Coast following what the show's producers said was a "breach of the rules".
Contestants were filmed constantly during show and the incident, which occurred about 4am (AEST) Saturday was not broadcast, but it was streamed on the internet.
Housemate John was seen lying behind fellow housemate Camilla, his arm over her. Ashley was shirtless and kneeling on the bed with his crotch in her face, his back is to the camera, his hand over the front of his pants.
On Sunday's episode of the Network Ten show, Camilla spoke about the incident in the "Diary Room", saying it happened "just in fun".
"... I wasn't offended as such but I did think they took it a little bit too far but, you know, we laughed it off," she said.
"I think as soon as I said enough's enough, it stopped. I've known these guys for a while and we were just mucking around."
Shortly afterwards, the Ten Network showed footage of Big Brother telling the shocked housemates that the pair had been removed.
Michael Bric's father, Herman Bric, said he was upset about his son being removed from the house.
"To see him spread like this (with headlines of) sex scandal, that's not him," an upset Mr Bric told the Seven Network.
Last week, Network Ten cut short its season of Big Brother - Adults Only.
