The Youth Disability Advocacy Service (YDAS) provides individual advocacy for young people with disabilities between the ages of 12 and 25 to pursue their rights and have a stronger voice. YDAS supports clients with advocacy needs in areas including education, housing, employment and support services.

YDAS supports the young person with a disability by working with them to identify what they want to achieve and assisting them to develop and implement a plan for how to achieve it. YDAS may support the client with letter writing and telephone calls, as well as arranging and attending meetings that are all aimed at achieving the outcome that the client wants. YDAS also assist clients to advocate for themselves.

Established in 2006, YDAS is a core agency of the Youth Affairs Council of Victoria. YDAS is funded by the Victorian Government.
