Well, coffee is becoming a "thing" in Oz, but mostly we drink tea if it's a non-alcoholic beverage.
Alcoholic beverages, well, Aussies drink a lot of wine (apparently Australian wines are some of the best in the world, go try some Australian Wine, and see) and a lot of beer (Don't drink the beer we export though, it's rubbish swill being sold off cheap to people who don't know any better) but we're really opening up in ciders. There are some excellent Australian gins, and awful Australian vodkas.
When I turned 18 (Australian legal drinking age) my father was delighted, and took me to get a gin and tonic at a pub. I'd had some alcohol before that, sips from adult glasses, but it is traditional to drink in a corner pub when you come of age, whatever your gender (I happen to be female). That said, pubs are expensive, I don't tend to frequent them, other than on a unique occasion such as that. I got to the drive-through bottleshop to buy my booze. I guess that shows some drinking cultural stuff. Do other countries have drive-throughs?
My friends all brew mead, ginger beer, cider, and so on. It's a lot cheaper than buying in a pub, or at a bottleshop. It's legal to brew here but not to sell your brewing without a licence, and it's illegal to distil liquor for any reason without a licence. Homebrew ginger beer, rich with herbs from the garden and full of alcohol brewed out of cane sugar, is an excellent thing to drink in this hot climate.
