The Australian Open did not begin at Melbourne Park, and for its first six decades it did not even stay in one city. The tournament started in 1905 as the Australasian Championships, and for the next several decades the event rotated among host cities across Australia and New Zealand, including Melbourne, Sydney, Adelaide, Brisbane, Perth and Christchurch, reflecting the tournament's original character as a shared championship of the Australasian tennis region rather than a fixed national institution.
The rotation ended in 1972, when the tournament settled permanently in Melbourne at Kooyong Stadium, the home of Australian tennis since the 1920s. Kooyong hosted the championship for sixteen years, through the sport's transition into the Open Era, before the tournament outgrew the venue's capacity. In 1988 the Australian Open moved to a purpose built stadium complex then called Flinders Park, later renamed Melbourne Park, on the south bank of the Yarra River. The move also brought a change of surface, from grass to a hard court, which the tournament has played on ever since, unlike Wimbledon.
Melbourne Park has since been expanded repeatedly, adding retractable roofs over its two largest show courts so that play can continue through Melbourne's January heat, a problem the tournament's earlier grass court era did not face in the same way. The stadium complex today hosts more than just the championship fortnight; it is also Tennis Australia's national training headquarters, tying the tournament's modern home directly to the sport's institutional life in the country that first hosted it in 1905.
