What is your point exactly? You are travelling in Australia and Australian regulations apply.
You do not need to show your boarding pass or ID to go through security when travelling domestically. You do not need to remove shoes etc when going through security.
However, I think you would struggle to find many air security incidents that have occurred in Australia because of the security practices used which could have been prevented with American style security.
I believe it is airline policy rather than law that hot beverages cannot be taken onboard.
"I'm not saying that this is necessarily a bad thing, I think that the states are over-the-top in their security at airports," is what I said. I just thought it was interesting that you can't bring a coffee on board the plane when the security is the way that it is. I wasn't attacking Australian regulations at all and think that the US can take a pointer from some of them at least (the no ID policy is weird to me though). I still don't understand the airline policy of not allowing coffee on the plane. Policies come to fruition for a certain reason - that reason is not clear at all IMO in this case.
