This is what we found on Wikipedia regarding the Formula 1 Australian Grand Prix:

The Australian Grand Prix is an annual Formula One motor racing event, taking place in Melbourne, Victoria. The event is contracted to be held at least until 2035. One of the oldest surviving motorsport competitions held in Australia, the Grand Prix has moved frequently with 23 different venues having been used since it was first run at Phillip Island in 1928. The race became part of the Formula One World Championship in 1985. Since 1996, it has been held at the Albert Park Circuit in Melbourne, with the exceptions of 2020 and 2021, when the races were cancelled due to the COVID-19 pandemic. Before that, it was held in Adelaide.

Historically, the Australian Grand Prix was held as either the last race of the season, when held at Adelaide, or as the opening round or early on at Melbourne. In 2022, it returned to the calendar as the third race of the season, following the Bahrain and Saudi Arabian Grands Prix. In 2025, the Grand Prix was moved back to the opening race slot of the season.
