Critical Rules

No punctuation in address lines (no commas, periods).
Suburb in CAPS on last line (with state + postcode).
Unit before street number: "Unit 14, 23 William Street" not "23 William Street, Unit 14".
PO Box: Replace street line with "PO Box 123" / "Locked Bag 456" — suburb/state/postcode same.
Rural: "RMB 123" (Roadside Mail Box) or "Care PO" + locality.
