The Homeless Youth Dual Diagnosis Initiative (HYDDI) is funded by the State and Commonwealth Government following the release of the 2008 Commonwealth Government White Paper The Road Home: A national approach to reducing homelessness and Project i by Melbourne University (2008).  HYDDI is implemented through a partnership between Hope Street and the NorthWestern Mental Health (NWMH), the mental health arm of Melbourne Health. A HYDDI Practitioner is employed by NWMH's Substance Use and Mental Illness Treatment Team (SUMITT) and is co-located at Hope Street.

HYDDI works with at risk young people in the Northern metropolitan local government areas, who have a dual diagnosis of mental health issues and substance use issues.  The aim of the initiative is to provide timely responses to issues arising from mental health or substance use, and limit the impact these have on a young person’s ability to participate in the community.

Hope Street also receives vital funding from the Victorian Government Department of Families, Fairness and Housing for young people within the Northern Division to access Housing Establishment Funds (HEF) to support their housing options.  HEF is jointly funded by the Victorian and Commonwealth Governments under the National Affordable Housing Agreement (NAHA).
