Sargent was quickest in all three practice sessions, qualified on pole, and proceeded to win all three races.
“Getting that first win in the bank was brilliant for the team, it's a great momentum booster that in hindsight we did carry through the weekend,” he said.
“This weekend has been amazing from everyone on the team, they've all done a fantastic job and given me a really fast car.
“Getting that pole was instrumental in setting up the rest of the weekend, being out front really allowed me to put my head down in the race and pull away.
“We've started the season on the front foot, and we don't want to lose that advantage, so we'll work hard between rounds to keep ourselves out front.”
Sargent holds a 13-point advantage atop the standings from Cody Burcher, with Jude Bargwanna third.
