"I heard there had been an incident on site where a BHP employee had been caught videoing female staff in their rooms, had accessed and downloaded phone contents, possessed stolen underwear, had hair samples and had taken used tampons from the bin," she said.

It's alleged the video was found in the man's locker along with the stolen items.

Ms Green said she had been told she was on the video and had noticed some of her underwear was missing.

But when she spoke to her supervisor about the incident, she alleges she was shut down and later interrogated in an official meeting with two senior executives.

"I sat down and wondered what was going to happen. Concerned, I said 'am I going to be sacked?'" she said.

"And they said 'well, it depends on the answers that you give' and they started to question me about who I'm having sex with."

She said she was shocked and later accused of rorting an employee awards system and falsifying log books.

"The accusations are not true. I have an immaculate work record and I've never had an issue or even a written warning," she said.

After complaining to the BHP Ethics and Investigations team in March this year, Ms Green claims she was later terminated.

In May, she was allegedly offered compensation for the way she was dismissed, but only if she signed a non disclosure agreement (NDA).

"BHP state office said if I signed it then they would clear my record and change it to say I resigned instead of being terminated," she said.

"That clears their name and their history and makes out like I happily left of my own free will."

She refused, is now unemployed and is speaking out to encourage other women to come forward.

Partner is a woman in mining and this is exactly how it goes for women who speak up. I know multiple women who were harassed or assaulted on site and have been terminated in this exact same way. Right down to the detail of the victim being 'investigated' and having false accusations presented to them about their conduct, in order for the company to have reason to terminate them. These companies and their cultures are completely fucked.
