A woman who forged documents to traffic women into Australia to work in Fyshwick brothels pleaded guilty to the charges on Thursday.
Jamaree Suksom, 58, pleaded guilty to two counts of allowing an unlawful non-citizen to work in Australia and one count of presenting forged or false documents allowing a person to gain entry to Australia.
Three other charges against Suksom were dropped.
Suksom was arrested in July last year during police raids of Pink Girls and Chok Dee Massage where Thai nationals were found to be working illegally.
WorkSafe ACT issued a number of prohibition and improvement notices after the raid due to serious safety issues - including electrical safety, fire risks, and hygiene, such as high levels of mould.
A pre-sentence report will now be prepared for Suksom and she will reappear in court in September for sentence.
