About Us

Odyssey House New South Wales was founded in 1977 by Sydney businessman, Walter McGrath, following the death of his son from a heroin overdose. From humble beginnings, Odyssey House NSW has since grown to become one of Australia’s largest and most successful rehabilitation services; over the past 40 years we have helped more than 35,000 people turn their lives around.
