“This is in line with our strict policy of zero tolerance of excessive behavior that affects the safety, comfort and enjoyment of other guests.”

Police later confirmed they removed six men and one woman at Bradleys Head in Sydney Harbour on Sunday afternoon.

Some of the men removed from the ship were using the three-day comedy cruise as a bucks celebration.

 “One hell of a bucks party that’s it … just boys being boys,” one of the men told Nine News.

A police spokesman confirmed the incident involved an attack using glass.

The spokesman for P&O said that “while these occurrences are rare” the company has “no hesitation in taking strong action where necessary that adheres to this policy”.
