It's been billed as a "world class" facility that will be a "key contributor to the NSW economy".
However, Sydney's $70 million new speedway venue was last month deemed "unsafe" for drivers, causing meetings to be cancelled while the state government works to rectify drainage issues.
As the Harbour City endures its wettest start to a year on record, the facility has struggled to cope, and last month two meetings were cancelled because the clay track was too dangerous to race on.
The Sydney International Speedway opened at Eastern Creek in January, but Sprintcar Association of NSW President Mark Richards said it was "unsafe for drivers to be able to control the cars" after a downpour.
"Since the constant rain conditions in Sydney, the track has never been able to dry out, and I believe that's probably related to this drainage issue," he said.
The new facility replaced a previous track at Granville, which was demolished to make way for the Sydney Metro West driverless train line — due to open in 2030.
The state government acknowledged "unprecedented rainfall" had led to drainage issues at the new speedway, which were being "rectified".
"Sydney Metro is working with the operator to resolve the issue and additional drainage lines will be installed in the off-season," a spokesperson said.
The spokesperson did not specify how much the remediation works would cost.
John Kelly, a co-operator of Sydney International Speedway and Brisbane's Archerfield Speedway, said parts of the track would need to be dug up.
"I've been doing racetracks for 15 years, but I've never seen anything like what happened at Eastern Creek," he said.
"There's a few areas that will need major works on the track."
He said engineers would use cameras to check for damage in the drainage system, and that up to eight more pipes would be installed.
After two weeks of cancelled events, a race took place on May 28 and stakeholders are hoping for sunny weather until the last meeting of the season on June 11.
"Unfortunately there's some teething problems [with the racetrack]," Mr Richards said.
"But everybody is confident they'll be overcome and everybody's looking forward to a really good season next year."
