Beer in Australia
Drinking beer is ingrained in Australian culture. Although Fosters is promoted as an Australian beer overseas, it is rarely consumed by Australians in Australia, and is almost impossible to find. Beers are strongly regional and every state has its own brews: Coopers and West End in South Australia, Carlton and VB in Victoria, Tooheys in NSW, XXXX in Queensland, Boags and Cascade in Tasmania, and Swan in Western Australia. There are also local micro-brew choices, which can be harder to find, but are often worth seeking out. A wide range of imported European and American bottled beers are available in all but the most basic pub.

Light (Lite) beer refers to lower alcoholic content, and not lower calories. It has around half the alcohol of full strength beer, and is taxed at a lower rate, meaning it is also cheaper than full strength beer.
Bottle naming is a little easier: the standard sizes across Australia are the 375 ml stubby and the 750 ml long neck or tally. Cans of beer are known as tinnies and 24 of them make up a slab, box, carton, or a case.

Wine in Australia
Australia produces quality wine on a truly industrial scale, with large multinational brands supplying Australian bottleshops and exporting around the world. There are also a multitude of boutique wineries and smaller suppliers. Very good red and white wine can be bought very cheaply in Australia, often at less than $10 a bottle, and even the smallest shop could be expected to have 50 or more varieties to choose from.
The areas of the Barossa Valley, Hunter Valley, and Margaret River are particularly renowned for their wineries and opportunities for cellar door sampling, but northern Victoria and Mudgee, also have a large variety. You are never too far from a wine trail anywhere in southern Australia.
Try the local wines wherever you can find them, and ask for local recommendations. Try not to get taken in by the label, or the price tag. The best wine is rarely the one with the best artwork, or the most expensive price. However, it is probably wise to avoid the house wine if it comes straight from a cask (4-litre container). Wines at the cellar door are almost invariably sold at around 20% premium to the same wine in the shops in the local town.
If you still prefer overseas wines, the Marlborough region of New Zealand is usually well represented on wine lists and in bottle shops in Australia.

Spirits in Australia
Bundaberg Rum (Bundy) is an Australian dark rum particularly popular in Queensland and many Queenslanders will not touch any other brand of rum, while many other Australians will not touch Bundy. It is probably the most famous Australian made spirit, mass produced in Bundaberg and available everywhere.
You will have to search much harder to find other Australian distilled spirits, mostly from niche players, but there are distilleries in every state of Australia if you look hard enough. Drop into the Lark Distillery on the scenic Hobart waterfront precinct. Pick up a bottle of 151 East Vodka in Wollongong or after a few days in Kununurra you are definitely going to need an Ord River Rum.
Mixed drinks are also available, particularly vodka, scotch, bourbon and other whiskey mixers. Jim Beam bourbon is probably the most commonly drunk, so those from Kentucky should feel right at home. Spirits are also available as pre-mixed bottles and cans but are subject to higher taxation in this form, so it is cheaper to mix them yourself. Spirits are served in all pubs and bars, but not in all restaurants.
