It was a huge day for the 22-year-old who led from start to finish and took his first poll position, all on his birthday.

"Yeah it's pretty special," Boys said.

"I'm so grateful to a lot of people who have helped me get here.

"My parents (Peter and Leanne) and Terry have been incredible.

"Image gave me a great car this weekend and its good to have so many local businesses on the car to repay them too."

Boys perseverance has paid off after a testing time at Townsville.

The Border product was able to hold his nerve to maintain his lead the whole way at Sandown, despite having seasoned Supercar driver Jack Perkins sitting within a second of him for the whole 22 laps.

"I got a good start and the car felt great from the first corner," Boys said.

"I was conscious of not using up the tyre life too early but wanted to keep a bit of a buffer over Jack, so it was a bit of balancing act.

"Although the pace was still really quick, I just focused on keeping it smooth and tried not to think about too much.

"It was good that it was Jack behind me, because he's been around for a long time and he's a good clean driver, so I wasn't worried about being dive bombed into corner or that."

Next year will mark Boys' third season in the series, with a number of Supercar teams keeping an eye on him for a co-driver role in next year's Supercar endurance races, which includes the Bathurst 1000.

This has become the traditional path taken by young drivers on their way to a full time drive in the main Supercar series.

Sunday's performance should only enhance Boys' chances of taking the next step, but the Border racing product is still keeping his feet on the ground.

"This is great, what we've done this weekend," Boys said.

"All we can do is just keep doing our best and hopefully those sorts of opportunities will arise.

"But yeah, this is a big boost for our confidence that we can be at the front and compete at this level with the best, so it's a pretty cool feeling."

Boys will now head to the 2019 Supercars Super two series' season final round at Newcastle in two weeks time, where he will be keen to keep his winning momentum going.
