The Western Australia state government launched blueprints for a new plan to stop widespread child sexual abuse in Roebourne and West Pilbara.

Safe houses, a night curfew, alcohol restrictions and an overhaul of services were listed at the core of the government's latest bid to protect children in the area.

Child Protection Minister Simone McGurk said she cannot guarantee the plan will fix generations of dysfunction, however she has committed the government to increase child safety and bring an end to harmful behaviours.
