“The easiest place to commit a crime, and get away with it, is on a cruise ship.”

That is what Mark Brimble, the former husband of Dianne Brimble, said he learnt in the years following the 42-year-old mother of three's death.

Mr Brimble addressed a House of Representatives Social Policy and Legal Affairs committee in Brisbane on Friday to outlay his family's experience following Ms Brimble's death and the changes he believed needed to be made to Australian law to prevent another tragedy.

“We have laws for the banking industry, which are corporations, we have laws for the insurance industry, which are corporations, we have laws for the airline industry ... we need to have laws for cruise companies,” he said.

“They shouldn't just do what they want to do.”
