A Qantas flight has made an emergency landing in Darwin, with one passenger claiming a man on board had threatened cabin crew.

A Singapore-bound Qantas flight from Sydney has had to make an emergency landing in Darwin, with one passenger claiming a man on board threatened cabin crew.

The flight took off from Sydney Airport about 1.30pm on Sunday and was scheduled to arrive at Singapore Changi Airport just before 6.30pm, local time, but made an unexpected landing at Darwin Airport about 4pm, local time.

Qantas described the incident as a medical issue.

A Sydney to Singapore flight was diverted to Darwin due to a “medical issue” on Sunday.

Police were called to assist at Darwin Airport, with passengers waiting at least an hour before taking off again.

One passenger claimed to NT News a “disruptive” man who was “drinking from his own 750ml wine bottle” had repeatedly said the word “explosive” and threatened cabin crew.

“He was clearly agitated, belligerent and appeared to be heavily affected by alcohol,” the passenger claimed.

However, the Australian Federal Police said no report had been made by the airline.

AFP are the lead law enforcement agency at nine Australian airports, including Darwin.
