2025 Australian Formula Open

The 2025 Australian Formula Open: Driven by FRCA is a multi-event open-wheel single seater motor racing championship. This is the third season of the Australian Formula Open series, which was originally founded by two-time Australian Gold Star winner Tim Macrow in 2023 as a direct successor to the Australian Formula 3 championship.

When AFO's original organizers launched the AU3 Championship for 2025, the AFO moniker was taken over mid-year by the organizers of the NSW Formula Car Championship, an open formula championship run since 2011 as one of Motorsport Australia's State Championships. That saw that championship effectively be rebranded under the AFO guise.

The championship is planned to be run over five weekends and started on 22 February at One Raceway.
