The ad in the newspaper promised so much - the chance to work as a nanny aboard a luxury yacht.
And many young women, in their late teens and early twenties, took the bait.
The ads were actually a brazen trap by Australia's worst serial rapist.
Twelve women have come forward after being raped by John Collins and police believe there could be many more.
Over decades, this monster used his wealth and power to lure victims onto his yacht - and then intimidation and fear to silence them.
But the survivors of John Collins' depravity wouldn't stay quiet forever and on 60 Minutes this Sunday, they're speaking out.
These women are brave, courageous and empowering.
Born in Sydney on November 9, 1938.
