Biggs has been a journalist since 1989. She was a staff journalist for the Sunday Herald Sun in the 1990s and has since written five books.
Biggs' first book was a 2003 autobiography, called In Moral Danger, about her life up to the age of 22. The book tells of her sexual abuse from the age of 14 by a well-known criminal barrister. It explains the damaging after effects following her abuse, including time spent in a psychiatric hospital, escaping Cambodia weeks before it fell to the Khmer Rouge and being a prostitute in Japan. It also describes how she attempted suicide four times, received death threats and caused national headlines - all before the age of 22.
She now campaigns to raise awareness about treatment for offenders of child sexual and works in a remote Aboriginal community in the Australian desert.
