An Australian Border Force security outage has caused lengthy delays in airports across the country.
Passport control machines are reportedly down in Sydney, Melbourne and Brisbane international airports, with thousands of passengers experiencing massive queues at immigration.
A spokesperson from the Australian Border Force told news.com.au they are working to resolve the issue, and advised passengers to arrive at airports early for additional processing time.
"The Australian Border Force (ABF) is working with the Department of Home Affairs to resolve an IT systems outage impacting inbound and outbound passenger processing at international airports," a spokesperson said in a statement.
