David Reynolds set the fastest lap of the day to top the fourth and final Friday practice session in Townsville.

The Bottle-O Falcon driver traded the top spot with Scott McLaughlin in the closing moments of Practice 3.

The Fujitsu GRM Holden driver had moved 0.6s clear of the field at the start of his penultimate run, holding the top spot until Reynolds moved 0.07s ahead with just seconds remaining.

McLaughlin then trimmed the margin to 0.009s on his final lap before an even latter effort from Reynolds edged the gap back out to 0.05s.

James Courtney ended up third fastest having run as high as second before Reynolds’ stirring final tyre run.

James Moffat and Michael Caruso continued the Norton Nissan’s strong Practice 2 form in fourth and fifth respectively while Mark Winterbottom, Scott Pye, Alexandre Premat, Will Davison and Lee Holdsworth completed the top 10.

The session was punctuated by a brief red flag period at its halfway mark for debris on the circuit at the exit of Turn 6.

The results were again mixed by a combination of hard and soft pre-marked tyres, leaving the likes of points leader Jamie Whincup outside the top 10.

Garth Tander completed just four laps in his Holden Racing Team Commodore after an apparent kerb crunching-induced rear suspension failure.

The kerbs also caught out Fabian Coulthard, who lost significant track time after a front-end failure on his Lockwood Holden.
