Tony Clarke drove “28 hours and two sleeps” to watch High Limit International at the Perth Motorplex.

The octogenarian from Adelaide hadn’t traveled to the capital of Western Australia since 1975.

But after viewing the inaugural sprint car event in 2024, Clarke was determined to witness the top dirt trackers in the world battle for bragging rights and a record $110,000 (AU) purse.

“I want to see Kyle Larson,” said Clarke, who keeps up with the High Limit co-founder and NASCAR Cup champion through FloRacing and local media channels.

Clarke is also fond of High Limit champions Rico Abreu and Brad Sweet. He follows the stock car exploits of Kiwi Shane van Gisbergen and Australian World Series Sprintcars champion James McFadden when he races Down Under and abroad.

Clarke is the ideal racing fanatic Perth Motorplex hopes to cultivate over the next three days and beyond, not just in Australia but around the World.

The interest following the breakout High Limit International has exploded over the last year—particularly with the return of Abreu and Carson Macedo after last-minute injuries kept them out of action in 2024.

Buddy Kofoid’s dominant Boxing Day win on Friday, coupled with Corey Day’s comeback from 28th to second, simply whetted the appetite for more USA vs. Aussie battles.

Chris Mitchell, marketing coordinator for Perth Motorplex, credits the partnership between the speedway, FloSports and High Limit for growing the event.

“It’s huge because of the marketing and network reach that FloRacing has by tapping into America,” Mitchell said. “There are so many American patrons who are going to come for this event, who are spending their hard-earned money on being tourists to our part of the world. It’s huge.

“But the reach to the whole industry, when everyone perks up and realizes what we have here, it's almost been like a poorly kept secret. We're tucked away in this little corner of the world, but now everyone knows what Perth Motorplex is.”

Larson’s star power is not lost on Mitchell either.

“When he finally came here and saw the venue and immediately rolled out the statement, ‘This is one of the best tracks in the world’—that plays on repeat in our office,” Mitchell said. “It's like the greatest thing we've ever heard, right?”

McFadden described High Limit International as one of the top three sprint car shows in the World. Day described Perth Motorplex as one of the top three dirt tracks he has ever raced on. Day’s team owner and Perth regular Callum Williamson is parlaying his exposure from last year’s event to a Pennsylvania dirt track residency next summer.

Neither McFadden nor Williamson has ever encountered so many fans circulating through the pits hours before the first green flag flies. The price of a ticket not only admits fans to the grandstands but offers the opportunity to be up-close-and-personal with their favorite drivers.

High Limit’s economic impact on the region is certainly noteworthy. With more than $3 million generated from the event, Perth Motorplex was awarded “Business of the Year” for 2025 by the Rockingham Kwinana Chamber of Commerce for Tourism and Hospitality.

“The outlook is amazing,” said Perth Motorplex General Manager Gavin Migro. “Our team investment has grown and it has had a direct effect on the community. It’s so exciting that people know that the Motorplex is here.

“And our partnership with High Limit has grown as well. That’s put a spotlight on us. It’s not lost on us the opportunity that we’ve got. We’re honored to be the current custodians of what we’re doing with it, so let’s keep growing it to be bigger and better.”

Migro is just getting started in the second of a three-year deal with High Limit, which he hopes will continue well beyond 2026. After increasing this year’s purse by $10,000—and having Larson helicopter into the infield to deliver the bounty—Migro plans to offer $20,000 to win for each of next year’s prelim nights.

“I’m overwhelmingly proud and excited about what the future can bring,” Migro said. “What Kyle and Brad (Sweet) and the team at High Limit have done to grow High Limit in such a short amount of time is really exciting.

“We think it’s endless what we can do and where we can keep going. We’re pretty sure it will go beyond the next few years, that’s for sure.”
