No, us locals don't know them all either!
There's colloquialisms for a half: pot, or middy, mostly. Hobart will call a half pint a ten, because it's 10oz, but they also know what you're talking about when you ask for a pot or a half pint.
Then there's South Australia, which will serve you a pint at 425ml, a schooner at 285ml, no one there outside of specialty craft beer bars have any idea what a half pint is, and if you want a proper pint you need to ask for an imperial pint. I have never seen an 'imperial pint' advertised in Hobart - it's just called a pint there.

I don't drink as much as I used to so this might be a little outdated, but in Perth "Pints" are 570ml. It was rare, but becoming less so, for some places to serve you a 470ml schooner when you ordered a pint. We avoided those places.
