Australia is one of 3 countries in the world where if you mess with staff in the air
the Feds meet you at the other end, and that is not nice. They don't care WHERE you boarded or WHAT carrier you are on or what class you are flying. Heavy duty penalities, and air rage here has DECREASED I read due to this no nonsense enforcement. Amen to that!
