Yes, that's what the woman told me...but what is unsafe about it? You can get coffee on board the plane, so I don't understand why it's unsafe to bring your own coffee on the plane that is purchased post security.

Flying from SYD-MEL and, back in October, from SYD-CNS, I never had to take off my shoes, belt, hat, jacket, watch, wallet, phone or take my laptop out of my bag. I also brought in two opened containers of water and juice (forgot they were in my bag) and nobody said anything.

I also travel with a nebulizer that usually gets swabbed down in the states, or at the very least taken out of the bag and run through the x-ray on its own. Not here. 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, but I can't say that the security in Australia has been nearly as scrutinizing as it is in the US. So, with my past experiences in Australia compared to those in the sates, I'd consider their security to be lax.
