Due to the failure of the security inspection system, the terminal of the airport in all regions of Australia experienced a large-scale delay.
Thousands of passengers are trapped at airports in Sydney, Brisbane, Melbourne and Perth.
Due to the collapse of the Australian Border Service (Australian Border Force) system, the passport-checking machine did not work properly on Monday morning, causing a large number of passengers to queue up.
The airport border control system was shut down, which means that the customs officers had to manually check the passenger`s passport.
The airport in Sydney, Melbourne and Brisbane confirmed to the Australian Daily Mail that their departure flight was delayed.
Perth`s passport inspection system also crashed, but said they had not encountered delays.
A passenger, on Twitter, said, `"The Sydney airport security/ boarding team had a big turn around the terminal building, which was so crazy. I`ve never seen such a scene before."
Another tweet said: "I`m in the same line, it`s crazy! I`ve never seen such a long team."
Another netizen added: "The Sydney airport has never happened before, and the flight is now a delay in the delay."
The weekend`s extreme weather had already led to a large-scale delay, and the airport was in a state of chaos.
The incoming passengers arriving in Australia, however, are not affected.
The Australia/ Daily Mail has contacted the Australian Border Service for comments.
