Australian slang, a casual contraction of 'good on you' — an expression of approval, praise, or encouragement. Typically used to commend someone for an action, achievement, or attitude. It can be sincere or lightly ironic depending on context and delivery. 'Onya' is distinctly Australian in flavor and reflects the broader pattern in Australian English of enthusiastic contraction and informalization. Equivalent in spirit to 'nice one,' 'well done,' or 'props to you,' but with a uniquely Australian warmth.
You cooked a roast for the whole family on a Tuesday night? Onya, legend.
