Dozens of domestic flights have been delayed at Melbourne Airport causing chaos for passengers after a reported security breach.
All domestic flights had been grounded early on Monday morning, leaving passengers queued up across the airport terminal.
The shutdown was reportedly caused by a passenger needing to be rescreened by airport security after passing through unchecked.
A Melbourne Airport spokesperson confirmed the security screening process at Qantas Terminal 1 was shutdown between 6.25-6.50am.
The spokesperson could not confirm the cause of the shutdown as the terminal’s security systems were operated by Qantas.
Frustrated passengers took to social media on Monday morning to share their frustration at the delays.
Images and video from the airport showed long queues inside of the Qantas domestic terminal.
Campbell Fuller said: “Huge queues at Qantas Melbourne Airport security. Screening seems to be offline”.
He later added about 7am: “Finally an announcement. Qantas is calling passengers for early flights forward in the queues.
“This interruption is bound to cause massive delays all day.”
Domestic flights had been delayed between 20 minutes and almost an hour, according to the Melbourne Airport website.
Destinations such as Sydney, Newcastle, and Cairns had been impacted by the delays.
By about 7am, flights appeared to be running largely on time, with a Sydney bound flights delayed between 20-30 minutes.
Late last year, more than 200 passengers were removed from a Qantas flight because of a similar incident”.
Qantas has been contacted for comment.
