A Jetstar flight from Melbourne to Brisbane was delayed after a man allegedly boarded without a ticket. Crew reportedly found him at the rear of the aircraft and called police, who escorted him off before departure.

Flight JQ562 was scheduled to leave Melbourne Airport at 9.35am on Wednesday but departed about 30 minutes late. Jetstar confirmed it had responded to an onboard security incident, while witnesses claimed the man had initially been stopped before allegedly finding another way onto the Airbus A320.
