Australia Address Format
Australian addresses go from smallest unit to largest: recipient, street (with optional unit/level prefix), then suburb + state abbreviation + postcode on one line. Australia Post recommends writing the suburb in capital letters (e.g. SYDNEY NSW 2000) and using the standard state abbreviations (NSW, VIC, QLD, SA, WA, TAS, NT, ACT).
