The family has Ukrainian roots, which Jake once mentioned when discussing their connection to local Ukrainian workers in western Australia.
The Kostecki household was built on discipline and hard work. Brodie’s parents encouraged him to pursue his passion early. When he was a teenager, the family took a big step — moving him to the United States to gain experience in competitive racing. He raced in American stock car series before returning home to Australia to chase a dream that soon became reality.

He maintains strong ties to his family in Perth, visiting home between races and continuing to honour the traditions that shaped him.
Business connections and wealth
The family’s financial story goes beyond racing. Gene Kostecki founded alloy steel international (asi) decades ago. The company manufactured arcoplate, a patented wear-resistant steel used in mining and industrial sectors. This invention made the kosteckis one of western Australia’s well-known industrial families.
In 2021, the family took alloy steel international private through kostecki brokerage pty ltd, holding around 65 percent ownership. Company records also show sponsorship payments made to Kostecki brothers racing, proving how the family’s business profits helped fuel their motorsport ambitions. In 2025, asi was sold to the U.S.-based Lincoln Electric in a deal worth around 210 million Australian dollars.

Success and struggle
Like any racing journey, the kosteckis’ path had highs and lows. In 2024, Brodie faced a tough period when his team, erebus motorsport, lost key sponsors and media scrutiny intensified. He briefly stepped away from racing before returning mid-season to capture the bathurst title. It was a comeback story that reminded fans of his grit and professionalism.
Despite setbacks, Brodie’s confidence never wavered. His move to dick johnson racing in 2025 was both a new beginning and a testament to his strength under pressure. The crash at the gold coast 500 later that year — which left several photographers injured — was another reminder of the sport’s dangers. Still, Brodie emerged ready to keep competing.
