A uniquely Aussie style???? you mean like this

Another unique style that comes to mind is American Wheat beer - it has wheat in it but doesnt use a wheat yeast to ferment. They use an ale yeast so doesnt that make it an Ale, or a pale ale (but not of course an American Pale Ale) but it is not a wheat beer in my mind.
"American wheat beer is a brand new style, invented by specialty brewers in the United States only about 10 years ago. It may even stretch the definition of "style," for nowhere is the creativity and diversity of America's craft brewers better displayed than in the new wheat beers.
American wheat beer does not use the traditional German weizenbier/weissbier yeast. The whole point of American wheat beer is to avoid the typical spicy/phenolic character of German wheat beers, which many brewers and beer drinkers find objectionable or unsaleable. Most micro and pub brewers use a conventional ale yeast, but doubtless there are bottom-fermented versions in use."
Uniquely Australian - VB, Fosters, Tooheys New, Tooheys Old, Emu Bitter, Coopers Ale etc they are already undique to Australia are they not? Stone and Wood Draughts seems to me to have been designed to be something a little different and therfore unique.
It may be possible to make something uniquely Australian (Barons Wattle Seed ale) but I would hate to see a style created that is similar to the American Wheat which to me is not a unique style at all - we all make ales with plenty of wheat malt and ale yeast and those who started doing this 15 years ago didnt even know they were brewing a uniquely american style??!??
How about a witchety grub wheat using, BB, Aussie hops, Aussie rice and a lager yeast at an ale temp that would be unique?
The point is what are we already making that is unique to us?
I may be in a slightly cynical mood as I am out of work - time to get brewing.
