Shell Ford pair Scott McLaughlin and Fabian Coulthard are first and second in the championship, with Red Bull HRT's Shane van Gisbergen and Jamie Whincup third and sixth.
McLaughlin and van Gisbergen split the victories in Townsville last time out, and are the defending Queensland Raceway winners.
Van Gisbergen's Sunday success in Townsville was just the second win for Triple Eight this season.
"It should be a busy day," Triple Eight manager Mark Dutton told Supercars.com of the test.
"QR's a funny old joint. Some weeks it works for you and sometimes it doesn't.
"It's definitely something that is more technical than it looks, those six corners.
"As we said, next door's always very strong there.
"In the race meeting, they'll be keeping us honest and we'll be trying to work hard to keep them honest."
