Wiebenga was competing in the Victoria Super Sprint Series, which is described as grassroots racing in a safe, inclusive and fun environment with “light-hearted but spirited” competition.
Wiebenga, 61, was driving a Ford Falcon AU.
Victoria Police said the driver hit a pole and died at the scene of the accident.
The cause of death has not been made public.
The Marque Sports Car Association took to social media to pay tribute to Wiebenga.
“It is with great sadness that we share the news that a member of our MSCA family, Graeme Wiebenga, passed away following a critical incident at Calder Park Raceway on Sunday,” the MSCA said in a statement.
“A member of the FPV Club, Graeme first joined us at our Come and Try Day in December last year and became quickly hooked.
“He had a genuine passion for motorsport and loved spending time on track in his beloved AU Falcon.
“His enthusiasm and enjoyment of every event will be remembered by all who had the privilege of sharing the track with him.
“Our hearts go out to Graeme’s family, friends and loved ones at this incredibly difficult time.”
Wiebenga’s family has set up a GoFundMe (HERE) to assist with the cost of the funeral, which has already reached 80 percent of its target at the time of publication.
The Marque Sports Car Association also acknowledged the first responders and officials who attended the scene of the incident.
“We would also like to thank our officials, first responders and everyone at the event for their professionalism, compassion and support,” the statement continued.
“We have been deeply touched by the care shown by our MSCA family and the wider motorsport community.
“Graeme was doing something he truly loved, and he will be greatly missed.”
