A Qantas plane bound for Germany has made an emergency landing in Darwin after an unusual smell filled the cabin.
There were 305 passengers on board the Boeing 747 when it made its unscheduled stop late last night and passangers were put up in hotels while engineers investigate what was described by one passenger as a burning smell.
A Qantas spokeswoman says the captain of flight QF5 from Sydney to Singapore sought a priority landing due to an odour in the cabin, but it disappeared within 10 minutes.
The spokeswoman says reports that there was smoke in the cabin or that oxygen masks fell from the ceiling are incorrect and no medical attention was needed for any of the passengers or crew.
The flight set off from Sydney Airport at four o'clock yesterday afternoon (AEST) and arrived in Darwin at 8.30pm (ACST) and passengers are currently waiting for information on when their journey will resume.
Twitter users on board the flight described the experience.

He said they had been told they would be in Darwin until tomorrow night.
