Former Health Services Union boss Kathy Jackson has been charged with 70 theft and deception charges by union corruption investigators.

Victoria Police have been investigating the whistleblower’s conduct at the HSU from 2008.

Police on Wednesday said the 49-year-old NSW woman has been charged with 70 counts of theft and deception related offences.

She will 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 said 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.

Last August she was ordered to pay the HSU about $1.4 million, after the Federal Court found she misappropriated union money to pay for travel, groceries, entertainment and even her divorce.

Then in December, the Federal Court ordered Jackson pay another $997,349 in judgement interest and costs following a civil matter.

Jackson became a national figure after she blew the whistle on her predecessor, former Labor MP Craig Thomson, and former HSU general secretary Michael Williamson in 2011.

Williamson was jailed for at least five years for leeching the union of almost $1 million and recruiting others to hinder a police investigation.

Thomson was fined $25,000 after he was convicted of 13 counts of theft following cash withdrawals he made from a HSU bank account between 2003 and 2007.
