SOLO sex workers have condemned a proposal by legal brothel owners that they say will create a new breed of "Mr Bigs" in charge of the sex trade.

The Queensland Adult Business Association representing the state's 23 licensed brothel owners wants the escort services sector legalised and regulated, and the brothel owners want the ability to expand into the escort services sector.

But the Sexual Service Providers' Advocacy Network representing prostitutes has warned that such a plan would deliver the lucrative escort services industry to a handful of existing players, creating an unhealthy concentration of ownership of the state's sex industry.

Police Minister Judy Spence this year is due to finalise reforms to regulation the sex industry following a Crime and Misconduct Commission Report in October last year.

The CMC recommended against decriminalisation of the illegal escort services industry which, along with solo workers, makes up 75 percent of the trade.

While solo sex workers and legal brothel owners fight each other over the proposal, the Prostitution Licensing Authority is at loggerheads with the CMC over its plan to restrict advertising by the illegal sector and hence its business and growth.

Ads for social escort services, accused of being a front for prostitution, would contain the words `non-sexual' or `sexual services are not provided`, display ads would be banned, and authorities could `disable' telephone numbers advertised in the Yellow Pages for illegal escort services.

PLA chairman, retired District Court judge Manus Boyce, said the proposals were `largely a waste of time` because the illegal sector could use code words to describe the services available to clients and could get around advertising restrictions.

The PLA is responsible for enforcing advertising restrictions.

The Courier-Mail has been told the advertising recommendations could be circumvented on the Internet: even if the PLA monitored web pages, many ads for escort services would appear disguised as client recommendations in chat rooms and adult bulletin boards.

Restricting ads for illegal escort agencies appearing in interstate and overseas business publications, for example Japanese men's magazines, advertising sex services for business tourists would fall outside Queensland's jurisdiction, and Queensland authorities would have little chance of monitoring ads for illegal gambling in Queensland appearing in provincial Chinese publications.

Mr Boyce said the CMC's recommendation against legalising escort services because of its concerns about child prostitutes and trafficked women wasn't supported by fact.

``No instances of children or trafficked women have been found in licensed brothels which are subject to unannounced inspections,'' Mr Boyce said.

``The problem is far more likely in illegal operations. The proposal for escorts to be supplied by licensed brothels was supported not only by the PLA but by the Queensland Police Service, Queensland Health and the sex worker organisation SQWISI.

``Allowing licensed brothels to supply escorts is likely to reduce the size and profitability of the illegal industry.''

The Family Council of Queensland meanwhile has called on the State Government to prosecute all clients of prostitutes but to take no action against the sex workers.

President Alan Baker said ``naming and shaming'' all clients would dampen demand and the policy had worked in Sweden.

While Sweden claims success with this policy, Swedish prostitutes say otherwise.

In an online forum they said the policy has led to a spate of murders of sex workers who sought police help dealing with violent clients. They were accused of double-crossing clients and revealing their identity.
