A Senate estimates hearing has heard a P&O cruise ship spilled 27, 000 litres of food waste and grey water on the Great Barrier Reef marine park in August.
Deputy Greens leader Larissa Waters delivered Australian Maritime Safety Authority’s report, which had been supplied anonymously, and said the public had a right to know about such events.
Waters said cruise ship companies are less likely to take the issue seriously if they believe the public won’t find out about their pollution.
