Bali airport officials say an Australian couple forced an emergency landing after allegedly getting into a fight on board.

An Australian couple forced the emergency landing of a passenger plane after allegedly getting into a fight on board, Indonesian airport officials say.

The Scoot flight from Sydney to Singapore made the emergency stop at Denpasar’s Ngurah Rai Airport at 16.46 local time on Wednesday.

Medics took an Australian couple who were on board to hospital, says the head of Ngurah Rai Airport Authority, Yuli Sadoso.

Then, as the plane was preparing to take off again, a third passenger, an Estonian man, was removed for unruly behaviour, Mr Sadoso says.

“The two passengers were … Australian citizens,” he said.

“I don’t know the cause of those passengers getting wounded.

“I was only told that the two got into a fight on the plane.”

The couple is understood to be in a Bali hospital.

The Straits Times reports the woman suffered a suspected broken arm, but it was unclear whether the man was injured.

The Singaporean newspaper reported the third passenger was drunk and unhappy with the decision to stop in Bali.

He was expected to fly to Singapore on Thursday night.

The emergency comes just weeks after Australian Matt Christopher Lockley, 28, was removed from a flight at the same airport.

He was deported to Brisbane where he was served with a notice to appear in court in June, when it’s expected he will be charged with interfering with a crew member.

An automatically generated email from budget airline Scoot said it would respond to a request for comment in up to 10 working days.
