Jetstar passengers have been left terrified after the flight they were on from Sydney to Cairns had to make a "priority landing" when smoke filled the cabin.
Passengers aboard flight JQ956 from Sydnet to Cairns were forced to use clothes to cover their mouths in an effort to avoid breathing in the smoke, before it was diverted to Brisbane airport.
The plane made the emergency touchdown in Brisbane shortly before 6pm, almost two hours into the flight.
Video captured on board the flight showed Jetstar crew assisting passengers as the incident occurred, before helping to clear the cabin of smoke, the Courier Mail reports.
Passengers reported hearing a "scraping and grating noise" during the flight, before being told that an incident had occurred with the plane's second engine.
