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.

Today Odyssey House offers Residential and Community Services, as well as the Magistrates Early Referral Into Treatment (MERIT) program. Our Residential Services include withdrawal and residential rehabilitation programs, mental health programs, a Parent’s and Children’s Program, gambling and specialised group services, as well as numeracy and literacy education. Our Community Services include free counselling, as well as individual, group and specialised group sessions, and a Detox in the Community program.

These services are designed to assist clients in dealing with the underlying reasons for using alcohol and other drugs. These reasons may include low self-esteem; serious family/relationship issues; domestic violence and other trauma, parental drug misuse; and physical and mental health problems.
