The State Government will provide $600,000 a year for a metropolitan legal service for indigenous victims of family violence, including people who had been sexually abused.
Premier Colin Barnett said indigenous females were 35 times and males 22 times more likely to be hospitalised due to family violence compared to non-indigenous Australians.
"There are several family violence services for indigenous people in regional and remote Western Australia, but no dedicated service in the metropolitan area," he said.
"This new service will close the gap and provide legal support and counselling to Perth's indigenous population."
The Australian Bureau of Statistics estimates about 40 per cent of the State's Aboriginal population of 70,000 live in the metropolitan area.
Attorney-General Michael Mischin said Legal Aid WA and the Aboriginal Legal Service were often conflicted in assisting victims of family violence and sexual assault because the same services were representing the accused person.
The new service will focus on violence prevention and victim support, and is expected to be in place by May.
