There is absolutely no point in T3 having a separate international security check point for the sake of the tiny number of international flights operated from the terminal - there are only 2 x daily flights (SIN and LHR) and then a few a week to CDG/FCO.

Domestic security in OZ is like a dream. It's like flying was like in those 1980's movies. You don't even need a boarding pass to go through security at domestic terminals! Yup, want to wave someone off....you can escort them all the way to the gate. Want to meet someone off an incoming flight? Again, you can wait at the gate. There are no liquid restrictions at all, never have been.
