Thi Quynh Trang Vu, known as Nancy Vu, is facing prison time after confessing to taking part in a cannabis syndicate allegedly involving two other Vietnamese men and Illawarra couple Goran and Lily Despatovski.

Vu was arrested on December 19 last year and remanded in custody but has since been granted conditional bail.

It is not known when she fell pregnant however she appeared to be well advanced during her most recent court appearance, where she pleaded guilty to drug supply and proceeds of crime charges.

Several other more serious charges were withdrawn by prosecutors.

An agreed statement of facts tendered to Wollongong Local Court said police set up Strike Force Bugh in February 2018 to investigate the ongoing drug supply activities of Goran Despotovski and his associates.

Police documents said Vu was a "significant" member of the syndicate, which allegedly supplied large amounts of cannabis to Goran Despotovski, who on-sold the produce from his Wollongong home.

It is alleged she was recorded directly supplying Despotovski with 9.1kg of cannabis, worth an estimated $182,000.

It is alleged Vu and her associates used encrypted communication software called 'Signal' to organise the deals.

"[The system] uses the internet to send one-on-one and group messages, which can include files, voice notes, images and videos," police said.

"Further to being encrypted, Signal software has a timing system set by the user for messaging services that permanently deletes the messages once they've been read."

During a search of Vu's Punchbowl home, police located almost $220,000 in cash, designer handbags, jewellery, shoes, a black Mercedes and a large amount of cannabis.

Vu declined to be interviewed by police after her arrest.

She had her bail continued over the Christmas period and will face Wollongong Local Court on January 22 for sentencing. A background report will be prepared ahead of the proceedings.
