Detailed plans for Adelaide’s future MotoGP circuit have now been released, giving South Australians a clearer picture of what is proposed for Victoria Park and the surrounding Park Lands — and why the project is already generating strong debate.
The South Australian Government has unveiled the proposed design for the Adelaide Parklands Circuit, a new 4.13-kilometre, 15-turn venue that is set to host the Australian MotoGP from 2027, alongside the Adelaide Supercars Grand Final.
The project is expected to cost $96 million and would represent one of the biggest changes to Adelaide’s motorsport precinct in decades.
More than just a race track
While the MotoGP circuit is the headline feature, the project extends well beyond the racing surface itself.
The broader plan includes upgrades across the Victoria Park precinct, including:
- new landscaping and planting
- drainage improvements
- active transport links
- new public sporting courts
- facilities to support major events
- improvements designed to support year-round community use of the area
The Government says the project is intended to create a multi-use precinct rather than simply a once-a-year race venue.
The circuit is also expected to be used as part of the Tour Down Under from 2028.
Tree removal at the centre of the debate
The most controversial part of the plan is the environmental impact on the Park Lands.
According to the released proposal, 377 trees would be removed or cleared, including 42 classified as significant trees.
A further 88 trees are proposed to be relocated, while another 22 trees still require further investigation to determine whether they can be retained.
The Government says that of the 8,895 trees within the wider circuit precinct, around 95 per cent would remain untouched. It has also argued that many of the trees proposed for removal are unregulated, invasive, dead or in poor condition.
Even so, the number of trees affected has become the major flashpoint in the public debate.
Government promises replacement and “nature positive” works
In response to the backlash, the State Government says every removed tree would be replaced at a ratio of 10 to one.
That would amount to 3,770 replacement trees, delivering what the Government says would be a net increase in tree numbers across the Park Lands.
The proposal also includes more than 123,000 understorey plantings as part of a broader environmental response.
A separate $15 million “nature positive” package has also been outlined, including restoration and planting works intended to offset the project’s environmental footprint.
Supporters of the plan say that commitment shows the redevelopment can leave parts of the Park Lands in better condition overall.
Critics, however, argue that replacement planting will not immediately make up for the loss of mature established trees.
Why the Government wants MotoGP in Adelaide
The MotoGP move is being promoted as a major economic and tourism win for South Australia.
The Government has pitched the project as a way to create a major November motorsport period in Adelaide, with MotoGP and Supercars to be staged separately but within the same broader precinct.
Supporters say Adelaide’s CBD location offers major advantages over regional circuits, including easier access to hotels, restaurants, public transport and tourism infrastructure.
The project is also being framed as a way to strengthen South Australia’s major events calendar and attract interstate and international visitors.
Not everyone is convinced
Despite the Government’s enthusiasm, opposition remains strong from some community members, environmental campaigners and critics of the Park Lands redevelopment.
Much of that concern centres on the permanent changes to Victoria Park and the wider eastern Park Lands, particularly the loss of mature trees and the amount of infrastructure required to safely host motorcycle racing.
Some critics have also questioned whether consultation is happening too late, given the decision to bring MotoGP to Adelaide has effectively already been made.
That means the current public consultation process is focused on the design and associated works, rather than whether the event itself should come to Adelaide.
Public consultation now open
South Australians are now being invited to review the plans and lodge submissions during the consultation period.
Public consultation on the proposed circuit and associated precinct works is open until 20 September 2026.
Construction is expected to begin in December 2026, with the circuit due to host its first Australian MotoGP in November 2027.
That leaves a relatively short timeline for a project of significant scale, especially given the design, landscaping, infrastructure and environmental works still required.
A defining project for Adelaide’s future
Whether the Adelaide Parklands Circuit becomes a celebrated addition to the city or remains a source of long-running controversy may depend on how the final design is received over the coming weeks.
What is already clear is that the plan is about far more than motorsport.
It is a proposal that touches on how Adelaide uses its Park Lands, how major events are balanced against environmental concerns, and what sort of city South Australians want to build for the future.
For supporters, it is a bold investment in events, tourism and precinct renewal.
For opponents, it is an unnecessary reshaping of one of Adelaide’s most valued public spaces.
Either way, the release of the detailed plans has moved the debate into a new phase — and the public now has the chance to weigh in.
