A Sydney brothel madam accused of luring Korean sex slaves to Australia was a police informant, a court has been told.
Kwang Suk Ra, 46, of Greenacre, is accused of heading a syndicate that brought at least 10 women to Australia under false pretences and forced them to work up to 20 hours every day in her Surry Hills brothel.
She is one of five people charged over the sex racket allegedly worth $3 million.
Ra faced Sydney's Central Local Court today on a string of charges, including debt bondage, deceptive recruitment for sexual purposes and dealing in the proceeds of crime worth more than $1 million.
If convicted, she faces 25 years in jail.
In his application for bail on her behalf, solicitor Stewart Levitt said Ra had been an informant for the Asian Crime Squad.
Ra provided police with information about a Korean criminal gang operating in Sydney, he said.
She also co-operated with immigration authorities and the Australian Crime Commission (ACC) in the months leading up to her arrest, he said.
"She stuck her neck out and there's no question she's been helping authorities with regard to a criminal syndicate in Australia," Mr Levitt told the court.
Under cross-examination, federal agent Juan Castellaz-Faico said police "no longer wished to speak" to Ra.
"For a period of time Ra was providing NSW police with information . . . but her services have been terminated," he said.
Mr Levitt said Ra was simply the landlord of the $220-an-hour brothel, Cindirellas, where the women were allegedly forced to work after having their passports confiscated.
She leased the operation to a number of managers, he said.
Kay Marinos, for the Commonwealth Director of Public Prosecutions, said Ra pulled the strings.
"It's a sham, she's the real controller of the operation," Mr Marinos said.
The court was told Ra threatened the women, whom she allegedly duped into believing they owed her up to $40,000 ($NZ46,658.11) for their travel to Australia.
In denying her application for bail, Magistrate Allan Moore said Ra may have only helped the authorities to clear the field of rivals.
He said it was clear she had brought the women to Australia and if freed on bail, would try to prevent them from testifying.
Mr Moore rejected the argument she was unaware of what her tenants at the brothel were doing.
"She sits behind the scenes. . . removing herself from the frontline of the activity that takes place on a day-to-day basis," he said.
Ra was remanded in custody until April 30, when she will reappear before the same court.
Her co-accused, Na Kyung Kim, 42, Jin Hee Do, 35, Jin Woo Lee, 23 and Gin Taek Choi, 28, also appeared today before the same court on related charges.
Choi was granted bail on a $10,000 ($NZ11,664.52) surety and will be required to report daily to police.
Kim, accused of laundering the syndicate's profits, had her bail application denied. She was remanded in custody to reappear before the same court on April 30.
Neither Do nor Lee applied for bail and it was formally refused.
Both were remanded in custody, with Lee to reappear before the same court on March 20 for a bail application and Do on April 30.
