A Perth father who's had decades of pain, anguish and uncertainty since his daughter disappeared 30 years ago, is hoping a $250,000 reward will bring justice.
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.
Ms Cutler's father Roger says it's hard to even remember what his daughter was like.
"The effect on my family has been disastrous," he told reporters on Tuesday.
Finding out what happened to her was about closure, he said.
"I don't see any justice here."
The reward offered by the WA government is for information that leads to the conviction of the person, or people, responsible for Ms Cutler's disappearance.
