Where "Good On Ya" Comes From
Here's a genuine surprise: despite being one of the phrases most associated with Australia worldwide, "good on you" almost certainly wasn't coined here. Language researchers Patricia O'Conner and Stewart Kellerman traced two competing origin theories, neither Australian: etymologist Eric Partridge pointed to Cockney English, citing a "Good on 'em!" caption in a Punch cartoon from 10 October 1917; separately, Cassell's dictionary links it to Irish speech, via the Gaelic maith thú ("good to you," i.e. "well done"), which the authors consider the likelier source.
What Australia did do was adopt it early, use it constantly, and — through film, TV, and travel — become the accent the rest of the world associates it with. So it's a phrase Australians made famous rather than one they invented.

How Aussies Actually Use It
"Good on ya" works for almost any achievement, big or small — passing a test, finishing a tough job, or just doing something decent for someone else.
It can also carry a sarcastic edge depending on tone, used ironically when someone's done something mildly annoying rather than genuinely praiseworthy.
