The man was charged by the Australian Federal Police (AFP) following the incident onboard an international vessel that sailed from Sydney earlier this week.
The man was arrested when the vessel returned to port at the Overseas Passenger Terminal on Saturday. The incident was reported to have occurred at sea on Wednesday.
The suspect has been formally charged with one count of assault occasioning bodily harm under the Crimes Act 1900 (ACT), a charge that carries a maximum penalty of up to five years in prison.
He is scheduled to appear before Downing Centre Local Court in Sydney on February 18.
According to the AFP, the assault took place while the ship was outside Australia’s “outer adjacent area,” but was still subject to Australian law under the Crimes at Sea Act 2000.
The legislation allows Australian authorities to investigate and prosecute offences that occur on vessels connected to the country, even when they are beyond territorial waters.
AFP Detective Acting Superintendent Trevor Robinson emphasised that safety on international vessels is a priority and that alleged criminal conduct will be pursued regardless of where it occurs.
“The repercussions of alleged criminal behaviour remain even when an offence occurs at sea,” he said, adding that the AFP works closely with cruise operators and maritime partners to ensure passenger and crew welfare.
The cruise line has not publicly disclosed further details about the parties involved or the circumstances leading up to the alleged assault, citing privacy considerations.
