SYDNEY — Women in Australia’s defence forces launched a class action lawsuit Friday alleging widespread and systematic sexual violence, harassment and discrimination.

The case was served against the Australian government on behalf of women subjected to abuse at any time in a 21-year period between November 2003 and May 2025.

“The threat of war often isn’t the biggest safety fear for female ADF personnel, it is the threat of sexual violence in their workplace,” said lawyer Josh Aylward of legal firm JGA Saddler.

“Australians will be shocked by the reports of sexual violence and harassment, victimisation, rape and physical threats but even more disturbing are the brutal assaults against those women who dare make a complaint,” he said in a statement.

The case, lodged at the Federal Court in Sydney, is being pursued on an opt-out basis, meaning all women serving during that time are included unless they declare that they have not suffered from the alleged abuse.

Thousands of women were expected to join the class action, the firm said.

Australia’s Department of Defence said it was aware of the complaint.

“All Defence personnel have a right to be respected and deserve to have a positive workplace experience,” a department spokesperson said.

“There is no place for sexual violence or misconduct in Defence,” the spokesperson added.

“Defence acknowledges there is work to be done.”
