I believe Australia's first hi-jacking event took place on an F27 in ASP, recollect the offender was shot and killed on the tarmac there, early seventies?
No so, the first recorded was early sixties on a TAA Electra - was resolved by one of the crew concealing the fire axe under his uniform then sneaking up behind the would be hi-jacker and bashing him on the head with it. In the mean time the F/O who fancied himself as a karate exponent was trying to disable the fellow with a few well placed karate chops nearly lost a finger to the fire axe.
After that time all Australian aircraft were fitted with a baton and two pair of police hand cuffs, which were kept in a lock wired and sealed box on the flight deck.
