A woman has been charged over a violent brawl among several men on a cruise ship off Sydney during an argument about a queue for the toilets.

The 37-year-old Russian national allegedly struck a 21-year-old man with an empty wine bottle, causing a cut to his head, during a fight between several men, including her husband, about 1am on Sunday, police said.

The incident, which occurred during a bucks party, took place on P&O’s Pacific Explorer.

Six men, including the injured man, and the woman were removed from the ship at Bradley’s Head later in the afternoon.

The men were subsequently released without charge pending further inquiries, while the Russian national was charged with reckless wounding and affray.

She was granted conditional bail to appear at the Downing Centre Local Court on March 9.

The cruise ship was on a three-night round trip from Sydney when the glassing occurred.

P&O Cruises said it had no hesitation in cutting the trip short to ensure the safety of its passengers.

“This is in line with our strict policy of zero tolerance of excessive behaviour that affects the safety, comfort and enjoyment of other guests,” a P&O Cruises’ statement stated.

“While these occurrences are rare, we have no hesitation in taking strong action when necessary that adheres to this policy.

“The group removed today will no longer be welcome to travel with P&O Cruises or any of its associated brands.”
