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.
- December Boys: Daniel Radcliffe (English) as Maps.
- Pacific Rim: Max Martini and Robert Kazinsky who play the Australian father and son duo, Herc and Chuck Hansen, are really American and English respectively.
- Django Unchained: Director Quentin Tarantino (American) appears as an Australian slaver.
- Quigley Down Under: Alan Rickman (English) as Quigley's crooked employer Marston.
- Tropic Thunder: Robert Downey Jr. plays Kirk Lazarus, an Australian method actor who is playing an African American character (in other words, Recursive Fake American).
- Although the title character of Mad Max is an Australian, he has yet to be played by an Australia-born actor. Mel Gibson was born in America (but raised in Australia), and Tom Hardy was born in England.
- Mad Max: Fury Road also features Zoë Kravitz (American) as one of Immortan Joe's brides. Charlize Theron is an aversion as she keeps her own accent.
- In Natural Born Killers, Robert Downey Jr. plays Wayne Gale, a narcissistic golden-globe winning Australian journalist with his own TV show where he sensationalizes mass murderers.
- The film Irresistible has the British Emily Blunt playing the antagonist.
- Fierce Creatures:
- Kate Winslet in The Dressmaker and Holy Smokes. She used the same dialect coach on both films to properly get the accent down.
- Northern Irish born New Zealander Sam Neill plays the famed Australian painter Norman Lindsay.
- Canadian Pamela Rabe plays Norman's wife Rose. She did however live in Australia and became a citizen there in 1983, ten years before the film was made.
- Meryl Streep in Evil Angels, though more accurately a Fake New Zealander.
- Monty Python's Flying Circus (five English, the other American) did this several times, most famously with the Bruce Sketch. In it they play a group of stereotypical Australians all named Bruce who all teach in the Philosophy Department of the University of Woolloomooloo.
- M*A*S*H. John Orchard (English) has portrayed two Australian characters on the show: anesthesiologist Ugly John in Season 1 and MP Muldoon in Season 8.
- A girlfriend of Daphne Moon's in Frasier is an Australian model in Seattle - but played by an American actress whose Australian accent is every bit as shaky as Daphne's English one.

- H2O: Just Add Water stars the South African born Cariba Heine as Rikki Chadwick.
- Elizabeth Moss fretted about perfecting her Australian accent on Top of the Lake and spent six months studying it, to the degree that Jane Campion had to reassure her she'd be fine. She won an Emmy for the miniseries.
- The Good Place has Michael pretending to be a human in Season 3, and puts on a very poor "Australian" accent which somehow doesn't arouse any suspicion.
- Press Gang has British/American Gabrielle Anwar as Sam. However, she doesn't even attempt an accent: the only indications of her being Australian are the Aboriginal flag on the window of the room for the graphics department (of which she is the head) and her once using the distinctive Australian slang term 'drongo'.
- Crash Bandicoot: Dingodile has consistently been voiced by Americans.
- The Sniper in Team Fortress 2 is voiced by John Patrick Lowrie, an American born in Hawaii, and raised in Colorado. The game's accents are all designed to sound like caricatures of what 1960's Americans would imagine these accents to sound like.
- The titular character of Ty The Tasmanian Tiger was voiced by Australian voice actor Stig Wemyss in the first game. However in the second and third game, he was voiced by Greg Ellis, a British voice actor. Shazza the Dingo was voiced by American voice actress Debi Mae West in the third game.
- Monterey Jack in Chip 'n Dale Rescue Rangers speaks with an Australian accent. He is voiced by Peter Cullen (Canadian) in some episodes, and Jim Cummings (American) in others.
- Gargoyles: Dingo is another such character voiced by Jim Cummings.
- Even Bushwhacker Bob (also by Cummings) in Taz-Mania. Also in the show, Dan Castellaneta (American) even used an Aussie accent to voice Mr. Thickly, and Rosalyn Landor (British) voiced Bushwhacker Bob's mum and Constance Koala.
