Housing and homelessness bodies who have had their funding cut by the Abbott government say they do not know how they will continue to do their work beyond June.

Homelessness Australia, National Shelter and the Community Housing Federation of Australia found out just before Christmas that they would not have their federal funding renewed - even though the Department of Social Services has confirmed it finds their advice valuable.

Peak housing and homelessness bodies have had their funding cut.

Together, they have received about $825,000 a year from the Commonwealth, which made up about 90 per cent of their overall funding.

The groups say that if the government was serious about being more consultative, it should restore the funding because they provide evidence-based police advice on low-income and vulnerable people.
