Australian Story: Scott Neeson of Cambodian Children's Fund.

This is a story of rags-to-riches and back again, introduced by actor Heather Graham.

From a working class upbringing in Adelaide, Scott Neeson built a career as a top Hollywood movie executive, promoting blockbusters such as Titanic, Braveheart, Independence Day, and X-Men. It was a glamorous lifestyle, walking red carpets, partying with celebrities and dating models.

But after a holiday in Cambodia, Neeson made a deliberate choice to give it all up. Gone are the slick designer suits, traded instead for the cargo pants and hiking boots required to navigate the rubbish dumps of Phnom Penh.

He now owns 'nothing' but says he couldn't be happier as he works to help some of Cambodia's poorest children.
