A flight from Sydney to Thailand had to be diverted to Indonesia after a group of drunk Australians who were travelling together started fighting.
Jetstar Flight 27 was carrying 314 passengers when it diverted to Bali on Wednesday night after the six Australians who were on their way to the tourist island of Phuket became "extremely disruptive among themselves" and refused requests from the crew to calm down, the Australian budget airline said.
The airline said all six were removed from the plane in Bali, but officials there said only five men were held by airport security and now face deportation to Australia. It is not clear what happened to the sixth passenger.
Bali airport manager Trikora Harjo said an investigation concluded that the only reason the men started fighting was because they were drunk.
"They were not seriously injured, just bruised," he added.
Nine Network television showed footage of one of the men with a black eye being escorted by security guards from the plane. The report said another man was bleeding heavily in the plane from a broken nose.
Bali airport official Yusfandri Gona said the men will undergo health checks before they are deported.
"They drank too much beer and liquor on the aircraft. Some of them started fighting, yelling and punching each other and ignored other passengers and the cabin crew's requests for calm and order," Mr Gona said.
Nine Network reported the fighting broke out five hours into the nine-hour flight to Phuket.
"The other customers on board supported the decision to offload the group in Bali and thanked the crew," Jetstar said.
The plane continued on to Phuket an hour after landing in Bali.
The airline did not say whether it will pursue the troublemakers for the cost of the diversion.
