SmartGate passport control machines, which work with e-passports and use facial recognition technology to check travellers' identities, have malfunctioned, requiring passports to be checked manually.
The Australian Border Force (ABF) said it was working with the Department of Home Affairs to resolve the outage, which is affecting the processing of inbound and outbound passengers.
"A number of ABF and Department of Home Affairs IT systems impacted by an earlier outage have now been restored," a spokesman said on Monday afternoon.
"The Department is continuing work to bring all systems back online, ensure the integrity of the systems and resolve any ongoing issues."Follow Us:
