I remember a TV ad which was part of a public-service campaign about seatbelts, and the actors were really bunging it on with the Far North Queenslander-speak, which was amusing. And sometimes I'll pick a South Australian from the way they pronounce their "oh."
By way of justifying my posting in your thread, I should ask a question, shouldn't I? I considered asking your opinion on weighty matters like the cultural cringe, whether we as a nation are "over" the whole penal-colony-origin thing, and so on and so forth. But bugger it, I'm gonna go with:
Who's the best hope, do you think, in the 09-10 Sheffield Shield? Or are you saving all your energy for barracking for the Aussies in the Winter Olympics?
Winter Olympics may be good for the occasional "Bradbury moment" but barring that....
As for Cricket well I used to be really boned up on Cricket and Footy because I could go to a pub and steer conversation away from Cars and tools (which I am completely ignorant) and talk about girls (which I am only slightly more knowledgeable) or sport which I could talk about with some expertise. These days....I am out of the loop.
So that brings me to the first two questions which you posed
The Penal colony thing is I believe a position of pride with Aussies. Having said that it is seen as a sacred thing and making fun of it is the best way to start a punch up. Of course no Aussie would dare or would want to. I think it actually ties in very nicely with the "cultural cringe". We take great pride in being tough, laconic, honest, rough, larrikins but hate others viewing this as cultural empty or inferior. It feels to us a lot more truer and full of integrity other cultural standards. Unfortunately whilst we cheer and embrace Bazza MacKenzie, Dame Edna Everidge, Sir Les Patterson and Crocodile Dundee for the aspects of "real Australians" they portray there is also the risk of them being seen without the biased and "Ocker filters" as uncouth idiotic slobs. So we are caught in a difficult position. A love/hate relationship and polarised perspectives that exist in the same cultural identities.
Does that make any sense?
