Australia is a massive country that consists primarily of sand, rocks and poisonous animals. The vast majority of the country is difficult to access, and as a result, the majority of local geohashers are based in capital cities.
You can obtain a list of Australian geohashing groups in the Australia category. Canberra's is obviously the coldest, followed closely by the regions of the Antarctic that are administered by Australia.

Melbourne
The majority of Melbourne's urban area is evenly divided between two graticules, with the CBD and inner suburbs lying in the west graticule.
It is so much cooler (as in temperature, and as in awesomeness) than Sydney could ever hope (or want) to be. It is also cooler (as in great; fine; excellent; socially adept) than Canberra, though so is nearly everything (except maybe Adelaide). Plus Melbourne has good coffee.
Melbourne is stocked full of good looking, talented and of course modest geohashers. It's currently the most active graticule, comprehensively thrashing its nearby and less fortunate neighbours in South Australia. Frequent hashers are:
Adelaide
Located on the split of (-34,138) and (-35,138), Adelaide is the capital of South Australia. Due to the splits, the graticules also contain a number of surrounding towns on the both north and south of the city. Roughly 50% of the combined graticules is land, with the graticule used for meet ups will be the one closest to the CBD where possible.
Adelaide has the esteemable Unwise Owl steadfastly hashing his way through two graticules in style; other Adelaide hashers are Bob the Fish and Nathan.
Sydney
The Sydney graticule lies at -33 degrees latitude, 151 degrees longitude.
Sydney is Australia's largest and oldest city, and is full of interesting places and twisted, hard-to-find streets. It is a rich cultural tapestry with hidden surprises lurking around every corner, waiting to be found.
In other words, it's perfect for geohashing but suffers somewhat, namely because half the graticule is way out in the middle of the ocean. That doesn't stop Gormster and RikkyC who make an effort to get out and about to fly the flag for the New South Welshmen.
Brisbane
Brisbane (the city) is split into two graticules by a longitude line just west of the city centre. The eastern graticule at -27,153 is called Brisbane. The western graticule is inland at -27,152 and called Ipswich.
The Brisbane graticule contains the city center and densest population areas of Brisbane. However the graticule is also approximately 75% ocean, and 5% islands that are not easily accessible (especially on short notice). This leaves the graticule with only 20% viable area on short notice. The Ipswich graticule contains the outer suburbs west of Brisbane, as well as Ipswich, Mount Glorious, and alot of empty space on the way (but not quite all the way) to Toowoomba.
In terms of geohashing, Brisbane is kind of like a subterranean pacific ocean volcano; simmering away with potential but yet to burst through with an explosion of activity.
Canberra
The Canberra graticule lies at -35 degrees latitude, 149 longitude. It encompasses Canberra, Queanbeyan, Bungendore, Braidwood and a number of smaller towns.
The region consists of farmland, National Parks, a generally dry lake, and a few hills that are locally called 'mountains'. Also to be found are dirt tracks, ravines, cliffs and at least one mountain worthy of the name. Canberra (the largest city found in the locality) is more commonly known as the Politics, Porno and Pyro hub of the nation, but sometimes also referred to as Our Nation's Capital. We love our city. We especially love the porno(graphy), pyro(technics) and pro(stitute)s. Canberra is renowned for being a navigational nightmare due to its high number of roundabouts.
Canberra started out with a hiss and a roar back in the early days of geohashing, but appears to have atrophied somewhat. It's probably something to do with politics.
