So you've got an Australian character in your work. Unfortunately, the performer in question is American, British, or something else that isn't Australian. Don't worry - as with foreigners trying to be American or British, all that's needed to sell the illusion is an Australian Accent.
The specific accent is usually Broad Australian; in reality, Broad Australian is one of several different Australian accents, but it seems to be the only one which appears in popular culture, leading to a self-perpetuating occurrence of Small Reference Pools where most foreigners wouldn't recognize any other Australian accent.
It should be noted that, to Australians, many attempts to imitate an Australian accent end up sounding like London Cockney instead.
- Both American Robert Mitchum and British Deborah Kerr in the 1960 film The Sundowners.
