Passengers trying to enter or leave Australia on Monday morning have been delayed following an IT outage experienced by the Australian Border Force (ABF).
The outage is affecting Sydney, Melbourne, and Brisbane international airports.
A spokesperson for the ABF told ZDNet the government entity is working to resolve the issue that is creating delays in processing both inbound and outbound passengers.
"The Australian Border Force is working with the Department of Home Affairs to resolve an IT systems outage impacting inbound and outbound passenger processing at international airports," the spokesperson said.
"Additional ABF staff have been deployed to process passengers and to minimise delays."
Passengers took to Twitter on Monday morning, sharing photos of long lines at the electronic passport gates which were reported as not working, resulting in staff processing passengers manually.
Advice to passengers from the ABF is to arrive at airports early to allow additional time for processing. ABF did not provide a timeframe for when it expects the outage to be rectified.
Passengers heading overseas can now receive their boarding pass on a phone as the next move towards automated travel at Australian airports.
Sydney Airport is trialling the first phase of biometric technology rollout alongside Qantas, allowing international travellers to check-in, drop off luggage, access the lounge, and board the plane.
The change follows a person using a passport belonging to someone else to leave the country through eGate.
The country's newly crowned Minister for Home Affairs Peter Dutton has said facial recognition at airports in Australia is merely a few 'technology generations' away from being rolled out.
A new federal program called Biometric Exit would match the photos of visitors flying out of the US to their visa photo, in an effort to curb illegal immigration.
