Australian English vs American English

Like any language, English changes depending on where it’s spoken. Talk to an American and an Australian and, beyond the accent, you’ll hear different words for the very same thing, plus a few differences in spelling. Here’s a clear rundown of how Australian and American English compare, in vocabulary, accent and spelling, so nothing catches you out.

Quick takeaway: Australian English is closer to British English than to American English. The main differences are vocabulary (Australians say arvo, thongs, servo), accent (Australian is non-rhotic, the final “r” goes quiet, while American is rhotic), and spelling (Australia follows British conventions: colour, organise, centre). The two are completely mutually intelligible, so don’t worry, you’ll understand both.

Australian vs American vocabulary

Australian English is closer to British English, but some words are uniquely Australian. Here are 20 common terms with their American equivalents and what they mean.

One thing you’ll notice straight away is the Australian love of shortening words. Australians take a longer word, trim it down and add an “-o”, “-ie” or “-y” on the end: afternoon becomes arvo, breakfast becomes brekkie, a service station becomes a servo, sunglasses become sunnies, a mosquito becomes a mozzie, and a barbecue becomes a barbie. It’s a friendly, casual habit that runs right through everyday speech, and once you spot the pattern, a lot of Australian slang suddenly clicks into place.

Australian English vs American English vocabulary

Accent differences

The accent is usually the first thing you notice, and the two go about it quite differently:

  • The “r” sound. Australian English is non-rhotic, like British English: the “r” at the end of a word (car, here, mother) goes almost silent. American English is rhotic and pronounces that “r” clearly.
  • Vowel sounds. Many vowels differ. The “a” in words like dance and path is broader in Australian English, and the Australian long “a” (as in mate) sounds noticeably different to American ears.
  • Rising intonation. Australians often let the pitch rise at the end of a statement, which can make a sentence sound a little like a question.
  • The flap-T. Americans soften a “t” between vowels into a quick “d,” so water sounds like “wadder.” Australians soften it too, but the overall rhythm and vowels still sound distinct.

Spelling differences

Because Australian English follows British conventions, its spelling differs from American English in predictable ways:

Australian (British) spelling American spelling
colour, favour, behaviour color, favor, behavior
organise, realise, recognise organize, realize, recognize
centre, theatre, metre center, theater, meter
travelling, cancelled traveling, canceled
