A 36-year-old man has been extradited from Western Australia to Darwin in connection with an alleged assault at the Darwin Waterfront in March 2023, Northern Territory Police said in a statement published on 19 September 2026.

Police allege that the man assaulted his former partner and three unrelated people who intervened during the incident at the Darwin Waterfront on 8 March 2023. He was arrested shortly after the alleged incident and was later granted Supreme Court bail, which allowed him to return to Perth.

According to Northern Territory Police, the man's subsequent circumstances in Western Australia prevented his immediate extradition to the Northern Territory. NT detectives from the Northern Domestic and Family Violence Investigation Unit later obtained a Northern Territory Supreme Court warrant for his apprehension.

The man has now been brought from Perth to Darwin to face the outstanding Northern Territory allegations. Police said he is expected to face four counts of aggravated assault, one count of unlawfully causing serious harm and one count of aggravated unlawful entry.

The alleged offences date back more than three years, so this is a current legal and police development rather than a new incident occurring today. The extradition allows the Northern Territory court process concerning the allegations to continue.

Police said the man is expected to appear before the Northern Territory Supreme Court on Monday, 21 September 2026. The upcoming court appearance will provide the next stage in the legal proceedings.

The allegations relate to an incident at one of Darwin's prominent public locations, the Waterfront. Police investigations into historical assault matters can require officers to maintain contact with witnesses, gather evidence and coordinate legal processes across jurisdictions when an accused person is located outside the Northern Territory.

The extradition also demonstrates the role of cooperation between jurisdictions when a person wanted in relation to alleged offences is located interstate. In this case, the man was brought back to Darwin from Western Australia after NT investigators obtained the necessary Supreme Court warrant.

The charges are allegations and have not been proven in court. The accused is entitled to the presumption of innocence, and the final outcome will be determined through the judicial process.

Northern Territory Police have described the matter as relating to alleged offences from 2023, while the latest development concerns the man's return to Darwin and the expected court proceedings. Further details may emerge when the matter reaches the Supreme Court on 21 September.
