New Zealander among those killed in Darwin shooting

A New Zealander has been confirmed as one of the men killed in a shooting in Darwin.

A spokesperson for Ministry of Foreign Affairs and Trade verified reports on Thursday.

The man was 52 years old, and has been identified as Robert Courtney.

Courtney was a security guard at Mindil Beach Casino Resort, according to Fairfax. 

A statement provided to Northern Territory News from resort manager Mark Bennett said Courtney was "a valued member of our security team,"

"We extend our deepest sympathies to his family and friends at this difficult time," he said.

Courtney matched the description provided by MFAT.

He was one of four killed after a gunman went on a shooting spree across Darwin on Tuesday. A woman was also injured.

After firing at a motel, the shooter then drove across Darwin in a ute, visiting three other locations where he killed a man in each.

He was arrested an hour after he opened fire and it is expected he will face four charges of murder.

The alleged gunman was known to police with a lengthy criminal history, investigators say. He was released on parole in January.

At the time of the shooting he was wearing an electronic monitoring bracelet.

He was arrested after calling police and asking to be placed into protective custody.

The shooting is not thought to be an act of terrorism.
