Australian Federal Police have swarmed to Adelaide Airport, an airport spokesperson said. The gates and concourse were evacuated as a security breach is unfolding.

An airport spokesperson said that passengers were moved to the check-in area.

At least one flight has been delayed.

Adelaide Airport authorities said the terminal had been evacuated due to a ‘security fault’. They issued a post on social media:

“Adelaide Airport has evacuated customers from its Terminal 1 concourse due to an issue with security screening.

“It is understood there was a fault with security screening equipment shortly after 2pm, allowing a small number of customers to enter the concourse without proper security screening.

“All customers were moved out of the sterile area, a sweep conducted, and customers are currently being re-screened and allowed to re-enter the concourse.

“It is anticipated there will be some flight delays and passengers should check with their airlines for their flight status.”
