Australian slang

A distinct English dialect built on shortening (arvo, servo, brekkie), inversion (no worries means yes), and a baseline ironic register where compliments and insults sound nearly identical. Around 2,000 active terms.

A mix of British English (heavy 19th-century working-class influence), Aboriginal English borrowings, surf and beach culture, outback dialect, and Sydney/Melbourne street slang.

A few core terms (mate, no worries, throw shrimp on the barbie — which Australians don't actually say) are widely understood. Most Aussie slang requires translation for outsiders.

Mate (form of address), no worries (yes / welcome / no problem), heaps (a lot), reckon (think), and the diminutive suffixes (arvo, servo, brekkie, sunnies). These cover most everyday speech.
