In Australia, you are right,In Australia, you are right, it is a common to say that the seasons start on the first of the equinox month. But that is because it is spoken by purveyors of ignorance. Anyone sweating through a 30C+ day well into March would hardly say we are having Autumn weather. The 'seasons' are far more closely aligned to the equinii, all around the planet, including Australia. Shameful that many students in school here have no idea what makes a season, other than a date rolling over to the first of the month. Thankfully the idea of seasons is slowly changing here, to be more in line with how the rest of the planet undertand them to be.
