The family has raised questions after a father of three went overboard from a cruise ship after losing $9,000 over two nights on the P&O Pacific Adventure.

Shane Dixon, 50, first lost $5,000, then borrowed money off his mother and lost another $4,000.

Dixons family maintained he was lured by high-roller incentives into losing the money.

Dixon died after falling overboard while sailing on the Pacific Adventure just after 4 am on May 6 as the vessel approached Sydney Harbour.

Now fellow passengers, some of whom were with Dixon in the casino, are asking why the rules for ship casinos should be different from those on land.

And they questioned the practices of giving out free drinks and free cruises to incentivise gambling.
