Kathy Jackson on theft, deception charges

Former Health Services Union boss and whistleblower Kathy Jackson is facing 70 theft and deception charges over allegations she misappropriated union funds.

Police charged the 49-year-old NSW woman one Wednesday and she's due to appear in the Melbourne Magistrates' Court on September 19.

Jackson was charged by Taskforce Heracles, a joint Victoria and Australian Federal Police operation investigating matters arising from the Royal Commission into Trade Union Corruption and Governance.

An AFP spokesman said the charges relate to matters that had been aired during civil action against Jackson over her time at the HSU.

A man who answered Jackson's home phone number told AAP on Wednesday they were "not in a position to take calls".

Officers raided her Wombarra home in October 2015.

Jackson declared bankruptcy last year and owes the HSU about $2.4 million following Federal Court action.
