BROTHEL owners would have to register their business with a government agency as part of the latest push to decriminalise prostitution.
Labor backbencher Steph Key will introduce new laws to Parliament next week to decriminalise all forms of sex work, after a previous attempt was rejected by one vote in November.
The new Bill, based on a New Zealand model, would require owners of brothels to register their business with Consumer and Business Services.
This would allow local government more regulatory control over brothels but the legislation would prevent councils from outlawing brothels simply because they offer sex work.
"Sex work premises would have to go through the same planning approvals as any other business," Ms Key said.
It is believed there are about 2000 sex workers in SA. Premier Jay Weatherill said he supported prostitution law reform in general but was yet to consider the latest Bill.
Ms Key's previous legislation - which was co-sponsored by Status of Women Minister Gail Gago - dropped provisions for barring brothels within 200m of suburban schools, childcare centres and churches after concerns were raised about difficulties policing the measure.
However, Ms Gago expected distance provisions might need to be included in the final version - to be introduced on Thursday next week - to get it over the line.
The Bill bars minors from conducting sex work and sets fines for sex workers who offer unsafe sex.
It would also create a Prostitution Law Advisory Committee, which would consider codes of practice, research and safety standards and report to government.
A number of MPs were absent from Parliament for the vote on the previous Bill.
Labor MP Lyn Breuer is also back on the floor of the Lower House to vote after stepping down as Speaker, to be replaced by Michael Atkinson.
Ms Key and Ms Gago were confident the new attempt was more likely to pass.
Opposition status of women spokeswoman Vickie Chapman said she had no objection to some regulation of the industry but added the new legislation needed to deal with the question of workers' compensation.
"What is the (WorkCover) premium going to be, what is the payment going to be for back injury - these are the realistic outcomes," she said.
Ms Gago said it would be important to bring on the vote soon so it did not "create too much noise in the background" of the March 2014 state election campaign.
Politicians will be given a conscience vote on the issue.
