A mother of six accused of using a bogus terminal cancer diagnosis has been exposed as a fraud that fooled everyone she knew including family and her partner.

Elizabeth "Elle" Edmunds concocted a tale in April in which she was diagnosed with ovarian cancer that spread to her lungs in September.

A man claiming to her defacto partner was sharing her story on a Facebook page, but now he claims to have been conned too, the Daily Telegraph reports.

"She never had cancer," the man wrote about his 31-year-old partner.

As well as shaving her head, Ms Edmunds wrote about her fantasy funeral and pulled several charitable victims into the scheme.

"She made everyone ... believe it. She made us do everything for her and if we didn't she would guilt trip us saying we didn't care she had cancer," one woman wrote.

The newspaper reports that Ms Edmunds netted $500 eftpos card and a donation site collected $2000 before it was disabled.

Roberta Williams, former partner of late Melbourne crime boss Carl Williams, even helped organise a $150 per-head dinner for Ms Edmunds before the tale unravelled.

"It's sad because it has made me not want to help anyone else," she said.
