Like many English-speaking countries, there are different ways of speaking English in Australia.
We don't have anything as radical as dialects here, but there are 3 distinct forms of English pronunciation here in Australia.
Low-Aussie: Very low, base, coarse pronunciation. Once very widespread throughout Australia. The type of accent that most people think of when one considers an Aussie accent. It's not so common these days. My quote is written in this form.
Mid-Aussie: This type of Aussie-English pronunciation is that which is used by the majority of the population these days. It is delivered with a noticeable Aussie accent, but not as broad or coarse as in the common type as expressed in my quote. Think of Heath's true speaking voice. Mine too!
High-Aussie: The way English is spoken by those who consider themselves better than the rest of us. It's a nasty, pseudo-intellectual hybrid of Etonian English and Aussie-speak. Spoken by would-be intellectuals and socialites. The snobs' accent!
