The opening practice was headed by in-form New Zealander Fabian Coulthard, showing the benefit of laps on the track in a recent promotional tour to head off James Moffat and Shane van Gisbergen.
It was another New Zealander in the form of 19-year-old Scott McLaughlin who stormed to the top in the second practice session just ahead of compatriot van Gisbergen in 1:34.22.
"When you get on the track and you go up the hill, it's pretty amazing," McLaughlin said. "I'm amazed at the undulation. It suits me down to a tee. You've got to keep the momentum up, it's quite flowing and I enjoy it."
Van Gisbergen pushed the Tekno VIP Holden to the fastest time in practice session three in 1:34.53 to edge out Coulthard as the New Zealand trio continued their strong form this season.
However the big boys came out to play in the final session as Lowndes produced a blistering 1:32.90, with van Gisbergen back in 10th, McLaughlin 16th and Coulthard 17th.
Championship leader Jamie Whincup was out of the top-10 throughout the day but he was likely saving tyres. There are two qualifying sessions tomorrow ahead of two 100km races, with a repeat on Monday (NZT).
