Leaked child protection figures show the number of children in Tasmania waiting for child protection services has quadrupled in just over a year.

The ABC obtained the leaked figures from the Department of Communities, and revealed there were 280 cases as of March 8 that had not been allocated a child safety officer.

Assistant secretary of the Health and Community Services Union Robbie Moore, said, “this is an urgent situation, these figures demonstrate vulnerable children are not being given the services they deserve.”
