In a blistering attack, the Canberra-based party's public officer Robbie Swan warned councillors they could be prosecuted under anti-discrimination laws if they rejected the brothel development application (DA) on moral grounds.

The application for Griffith's first brothel, planned at the old Risque site in Hams Street, is currently stalled after it was discovered the brothel's operators, Sky Night Angels, failed to fill out the DA forms correctly.

It is expected to come back before council at a coming meeting.

Mr Swan said there was "absolutely no reason" the brothel should not go ahead.

"It's a legal business and should be treated the same as a doctor's surgery and located in the same area," Mr Swan said.

"It's a slippery slope when you start judging on moral standards and I really think councillors would be risking the health and safety of the community by rejecting this brothel and pushing the profession underground.

"And I think the church are moral hypocrites to be opposing this. There are more paedophiles in the church than any organisation in Australia - more than 600 have been convicted.

"There hasn't been one person from the adult industry ever convicted on such charges and I challenge the church groups to find one."

Mr Swan conceded that the majority of brothel clients were "cheating partners" but said such matters were an issue for couples, not brothel operators.

Brothels were legalised in NSW in 1994, giving sweeping new powers to local councils to regulate them.

"The reality is that sex workers are already part of the Griffith community, it's just that many of them choose to keep it private," Janelle Fawkes, CEO of the sex workers national peak body the Scarlet Alliance, said.

"They deserve the same kind of safe workplaces and rights as the rest of us and this notion that sex workers are somehow outside of the community is simply incorrect.
