2025 GT World Challenge Australia

The 2025 GT World Challenge Australia Powered by AWS was an Australian motor sport competition for GT3 cars. This was the second season since the SRO Motorsports Group took over sole management of the series. The season started at Phillip Island on April 5 and finished at Hampton Downs in New Zealand on November 2.

Calendar

The provisional six-round calendar was announced at the 2024 SRO Press conference at the 24 Hours of Spa. For the first time the series had a media day at Phillip Island. On 18 October, the calendar was updated, in which the Queensland round was shifted to June and the championship will return to Sandown Raceway after 3 years.
Unlike previous years where most race weekends were run by another promoter as part of the SpeedSeries event series, in 2025 the SRO has taken over as event promoter as well as category promoter. Other categories at the race meetings will include the Radical Cup Australia and GT4 Australia.
