A $250,000 reward is being offered for information about the disappearance of a Perth woman 30 years ago as the homicide squad launches a fresh investigation into the case.
Julie Cutler was 22 when she was last seen leaving the Parmelia Hilton Hotel in the early hours of June 20, 1988 after a staff function.
Her car was found two days later in the sea off Cottesloe Beach.
The reward money is being for information that leads to the conviction of the person, or people, responsible for Ms Cutler's disappearance, as the homicide launches a fresh investigation into the case .
The state government said it may also be prepared to consider recommending protecting an informant from prosecution, provided they weren't directly responsible for her disappearance.
"Julie's family have waited in pain, anguish and uncertainty for 30 years," Police Minister Michelle Roberts said.
"It's time this matter was resolved."
