Reforms to improve the lives of disabled people experiencing homelessness need political leadership and action, advocates say, with the vulnerable group targeted in a new plan.

The Disability Strategy, which acts as a framework for policy commitments from state and federal governments, will include an additional homelessness priority area, commitment to a new community engagement plan and three fresh action plans.

It was unveiled by National Disability Insurance Scheme (NDIS) Minister Amanda Rishworth in Melbourne on Wednesday.
