The youngest in their division, the Katherine girls make up just five women in a club of about 15.
"I am spurred on by the assumptions," Thomsen, 19, said, "I'm proud to prove them wrong."
Historically, women have helped in the pit, but the male dominated sport is seeing more and more females rejecting the sidelines for racing action.
"Everyone in Katherine is very supportive, but I have had throwaway comments that I'm not as good as the boys," Thomsen said.
"We always get a surprised look when we say we drive, people just assume we are part of the pit crew."
In fact, the 19-year-old is no stranger to the track.
The Katherine local was ranked the number two go-kart racer in Australia, in 2014.
The short-lived title ended after a crash involving a younger driver landed her in hospital.
"It has taken five years to get back into racing," she said.
"Paramedics thought I had broken my neck.
"I completely lost my confidence."
Despite a tough couple of years where she "shut off from the world", she couldn't completely separate from the sport, always helping on the sideline.
It took a complete change of tack, a push from the club and a best friend giving it a go for her to race again for the first time this year, but in a completely different class - NT Sedans.
"They have a five-point seat belt, and a steel cage securing you in. It made me feel safer," Thomsen said.
Meanwhile, Brittany Campbell was taking a leap of faith after helping her younger brother out for years while he raced formula 500's.
Having never raced or driven in Speedway and going on nothing but a gut feeling, she took the plunge and bought herself a working car and all the gear needed to go with it - not a light cost.
"I was chasing the rush," the 17-year-old said.
"I always loved to drive fast and after working in the pit for so long I wanted to be part of the action."
Both competitors had their first race early June, competing against racers with years of experience.
They had barely had any practice before taking to the track in front of hundreds of spectators.
"All I could feel was my heart racing, but once I started I didn't want to stop. There was never a worry I would't enjoy it," Campbell said.
Thomsen's first drive was filled with nerves as well.
"I thought I was going to vomit I was so nervous, but then I couldn't stop smiling I was so happy to be back out racing."
