Australians typically write the date with the day leading, as in the United Kingdom and New Zealand: The month–day–year order (February 13, 2025) is sometimes used, often in the mastheads of magazines, schools, newspapers,[3][4] advertisements, video games, news, and TV shows.
The ISO 8601 date format (2025-02-13) is recommended by the government to be used when communicating internationally.
The Australian government identifies Monday as the first day of the week,[6] which is consistent with the Common Locale Data Repository (CLDR) since its October 2021 release.
[5] The government also recommends a colon as the separator; however, the single period is still used in some contexts.
[5] They also suggest writing the noon/after noon qualifier as "am" or "pm" in lower-case without periods.
