Hundreds of people were stranded at Melbourne's International Airport for about an hour on Tuesday morning when outbound flights were delayed by check-in and baggage system problems.
Flights out of Melbourne have since resumed following the delay caused by a "network connectivity" issue that occurred at 9.30am AEDT.
The airport subsequently tweeted: "Airport network issue resolved. Please be patient while we process passengers through the terminal."
"We are pleased to advise that the technical issue has been isolated and was resolved shortly prior to 11.00am," Melbourne Airport then said in a statement. "We are working to resume normal operations as quickly as possible."
A spokesperson for the airport told AAP that baggage systems are now operational, and staff at the Tullamarine airport is in the process of checking people in and "getting them on their way".
ZDNet understands the fault was with the network at the airport, which is managed by the local airport authority.
"It is important to note that no safety or security systems were impacted during this brief outage," Melbourne Airport said.
The airport apologised for the disruption.
Last year, both Sydney and Brisbane international airport terminals experienced an outage due to its SmartGates that left passengers unable to use the SmartGates to enter the country.
The delays meant passenger processing had to be performed manually.
"Technical issues with SmartGates at #Aus int airports this morning have been resolved. Thank you for patience," the Australian Border Force tweeted at the time.
A fortnight to the day after the SmartGate failures at the airports, Brisbane International Airport again suffered from a SmartGate outage.
