Internationally, it's pretty uniform. No individual container of >100m in carry on. And you are supposed to put it all in a single ziplock bag no bigger than about 20cmx20cm.
What's a bit annoying is that domestically, its no so uniform. Australia has relaxed their laws on this sort of thing, but when I took an internal flight in Thailand a few weeks ago, they are following the international standard (l maybe the US standard, which they often follow on this sort of thing), and I had to leave a couple of things behind... my own silly fault for not double checking I suppose.
I do have a funny airport security story though. I have a thing/problem where I steal/take all possible hotel toiletries from everywhere I stay. I had that much time around that, I jammed the goods (shampoo/soap/toothbrushes,shaving kits etc) into 3 hard tubes which I had used the month before to transport some red wine over. When arriving at Brisbane airport last week, I had to declare something else (a wooden item i'd bought). and so did the right thing and said I had something to declare.
So anyway, the guy says he wants to xray all my gear, so I put my large suitcase through, and lo and behold, I am told there were some suspicious items in my suitcase, so off we go to another place where I am asked a heap of questions and told to open my suitcase. At this point, I'd worked out what happened, and said "its the tubes isn't it?". To which he nodded very seriously, so I opened one of them and he started taking out a shitload of toiletries tightly packed, which, on the xray machine must have looked like bags of drugs or something.
I then had to sheepishly explain my hotel toiletries fetish to the guy, who by now at least had lightened up and said "mate, your entitled to take them". And, after seeing the first tube didn't bother with the other 2. I guess he must see a lot worse than a soap thief.
And so now I can go another year of not buying toiletries
