The 2022 VALO Adelaide 500 has injected a record $51.85 million into the South Australian economy — the biggest figure in the history of the event.
The economic benefit was a 34.3 per cent increase on the most recent event in 2020, which generated $38 million.
The 2022 VALO Adelaide 500 was the first event in the South Australia capital since the 2020 round.
It was also the final Supercars Championship round for Holden, which has been replaced by Chevrolet from 2023.
The 2022 figure smashed the previous all-time record of $45.9 million set in 2019.
More than 12,000 people travelled to South Australia from interstate for the event, and there were an estimated 96,671 visitor nights in South Australia.
The 2023 VALO Adelaide 500 will be held November 23-26, and will be headlined by international superstar Robbie Williams.
The Adelaide event will round out Supercars seasons until at least 2026.
"The VALO Adelaide 500 was a resounding success on-track and now we know it was an incredible success off-track too,” Malinauskas said.
"Our tourism and hospitality businesses have done it hard over the past few years.
“These numbers reveal the return of a big event like the VALO Adelaide 500 gave local businesses a much-needed boost.
"Pubs and restaurants were packed, hotel rooms were full and more than $50 million was returned to the South Australian economy.
"I am incredibly proud we were able to deliver on our promise to bring back the VALO Adelaide 500 and make it bigger and better than ever."
VALO Adelaide 500 CEO Mark Warren added: "I am so proud of our team who worked so hard to bring back the VALO Adelaide 500 and deliver a memorable event.
"We are already working hard to go one better in 2023 and deliver another outstanding event for South Australia, with global sensation Robbie Williams confirmed to headline the after-race concert.
"The VALO Adelaide 500 showcases world-class motorsport, and we look forward to ushering in a new era in 2023 as we welcome Supercars Gen3 to the Adelaide Street Circuit."
The 2023 Repco Supercars Championship will commence at the Thrifty Newcastle 500 on March 10-12.
