A Tigerair Australia Airbus A320-200, registration VH-XUH performing flight TT-644 from Adelaide,SA to Sydney,NS (Australia), was enroute at FL380 about 170nm northnorthwest of Melbourne when passengers complained about fumes on board, a number of them also complained about ear pain. The crew decided to turn south and divert to Melbourne, where the aircraft landed about 35 minutes after leaving FL380. Two passengers were taken to a hospital.

The airline reported the aircraft diverted as a precaution due to an unusual odour in the cabin. The passengers were rebooked onto other flights.
