when does autumn start in australia

Autumn in Australia starts on 1 March and runs through to 31 May in the standard meteorological (calendar) system used across the country.

Some sources also talk about the astronomical start of autumn, which is tied to the autumn equinox around 20 March each year in the Southern Hemisphere. However, for everyday use—weather reports, school terms, tourism info—Australians generally treat autumn as beginning on 1 March.
