Madeline began her car racing career in 2019 stepping straight from go-karts to the third tier Supercar series Super3 Series with Brad Jones Racing To accelerate her learning she also raced in the Western Australian Formula 1000 State Championship.

Madeline intended to continue to race in the Super3 Series in 2020, with Brad Jones Racing as well as planning to race a Porsche 911 GT3 Cup Car in the Thailand Super Series with Earl Bamber Motorsport. The global COVID-19 pandemic changed those plans.

Madeline completed in round 1 of the Super3 Championship at Sydney Motorsport Park finishing 3rd. She later competed in two rounds of the Aussie Tin Tops, a series created to give people an opportunity to race during the pandemic. Madeline won the Super3 class at Townsville before swapping to a Porsche 911 GT3 Cup Car with McElrea Racing for round 2 at The Bend Motorsport Park where she finished 4th in the Super Stuttgart class.

In 2021, Madeline became one of the inaugural Porsche New Zealand Scholarship recipients. The scholarship provides partial funding for her to race in the Porsche Sprint Challenge Australia in 2021 with Earl Bamber Motorsport/Porsche Team New Zealand.
