Recently a security breach at Melbourne Airport forced hundreds of passengers to evacuate the Qantas and Jetstar terminal, causing delays on several flights. The scare was sparked by a person mistakenly entering the terminal through an exit without going through a security check, Qantas spokesman Tom Woodward said.

Woodward said the entire Qantas and Jetstar terminal had to be emptied as a result, with emergency evacuations beginning about 7.15 p.m. When the terminal reopened about 8.30 p.m., passengers who had been screened by security had to be sent through for a second time. Flights from the terminal resumed about 9 p.m. “The whole process took about an hour and a half,” Woodward said. “Five domestic flights were delayed by about an hour.”
