Overview
- The South Australian government publicly revealed the 4.13 km, 15‑corner Adelaide street circuit on Sunday, August 30, and confirmed the project budget at about A$96 million with public consultation opening August 31 to September 20.
- MotoGP modelling and designers say the layout will let bikes reach roughly 343 km/h and produce premier‑class lap times near 1 minute 26 seconds, and the design was developed with the FIM and advisors from both MotoGP and Supercars.
- Construction is scheduled to start in December 2026 with completion targets given between April and November 2027 so the circuit can host the 2027 MotoGP weekend, though officials say those windows could change if legal or community challenges arise.
- The redevelopment requires removal, relocation or investigation of hundreds of trees with reported figures that vary by source; the government has pledged to relocate some trees, plant roughly ten replacements per tree removed, and set aside about A$15 million for habitat and green‑space work even as opposition groups and a 43,000‑signature petition push back.
- Planners say the circuit will have separate MotoGP and Supercars configurations with different kerbs, barriers and corner profiles to meet motorcycle safety homologation and preserve touring‑car character, and officials present the project as a legacy upgrade to public parklands and local event capacity.
