An IT problem is causing chaos at Australia's international airports, with significant delays in processing inbound and outbound passengers sparking long queues.
Passengers have been posting photos of long queues from the international terminals in Sydney - where people were forced to wait for almost two hours - and Melbourne.
However, every international airport in the country has been affected. In a statement, the Australian Border Force (ABF) said it was working with the Department of Home Affairs to resolve an "IT systems outage". "Additional ABF staff have been deployed to process passengers and to minimise delays," the statement read.
"Passengers are encouraged to arrive at airports early to allow additional time for processing."
