Airlines in Australia are again cancelling flights en masse as the country's two major airports face 48-hours of disruption caused by ash cloud from Chile's Puyehue-Cordon Caulle volcano.
Qantas, Virgin Australia, Tiger Airways and Jetstar have all cancelled flights across the country as ash continues to drift across the south of the country.
International flights due into Sydney have been diverted to Brisbane, ABC News reported, while earlier Qantas brought forward international departures due out of Sydney.
Australia's Aviation Minister Anthony Albanese says airports in Melbourne, Canberra, Sydney and Adelaide could be shut for up to 48 hours.
Mr Albanese says the Bureau of Meteorology estimates Adelaide will be affected for 24 hours, Canberra and Sydney for around 36 to 48 hours, and Melbourne for 36 to 48 hours from tomorrow morning.
