Mouzouris set about finding his feet at the South Australian capital, having made the move from open-wheelers after winning the 2019 Australian Formula Ford title.
The 18-year-old reported a productive day at Ipswich, where he had seven-time Bathurst 1000 winner Craig Lowndes on-hand to offer his wisdom.
“It almost felt like another off-season between last test day and now so it was good to get some laps under my belt again,” Mouzouris told Supercars.com.

“Good things take time so just any lap is more experience.
