Formula 1 had existed as a World Championship since 1950 without ever holding a round in Australia, a country with a genuine and long-standing motor racing culture of its own but one that had simply never featured on a calendar still overwhelmingly built around Europe, with periodic, often short-lived detours to the Americas and, more recently, Asia and South Africa. That changed in 1985, when the South Australian state government, in a bid to raise Adelaide's international profile, won the rights to host the season's second-to-last round on a temporary street circuit laid out through the city's East Parklands.
The Adelaide circuit was, by the standards of the era's street tracks, unusually well regarded from the outset — wide by street-circuit standards, with a good mix of fast sweeping sections and tighter technical corners, purpose-planned with genuine input from racing organisers rather than simply threaded through whatever streets happened to be available, in a way that avoided many of the compromises street circuits like Caesars Palace's parking-lot layout had struggled with. Its late-season calendar slot, combined with Adelaide's warm spring weather and a genuinely enthusiastic local crowd unfamiliar with but excited by their first taste of top-level international motorsport, gave the race an immediate festival atmosphere that many paddock veterans said reminded them of Monaco's mix of glamour and technical challenge, without the parking-lot compromises that had plagued some other new-territory ventures.
Keke Rosberg won the inaugural race for Williams in wet-to-drying conditions that tested tyre strategy throughout the afternoon, a technically demanding race that showcased the circuit's capacity for genuine racing drama rather than the procession some had feared from a brand-new, untested street layout. The race's success was significant enough that Adelaide retained its calendar slot for the following eight seasons, hosting several dramatic championship deciders — including the following year's controversial tyre-blowout finish — and cementing Australia's place on the Formula 1 calendar permanently, a foothold the sport has never since relinquished, even after the race itself later moved to Melbourne.
