Waters leads De Pasquale in first practice

A late flyer has helped Cam Waters pace opening practice at Wanneroo Raceway.

Waters was the only driver into the 53s, with the Tickford Racing driver quickest on a 53.989s.

Anton De Pasquale vaulted to second late on on a 54.161s ahead of Jack Le Brocq.

Le Brocq’s 23 laps was the biggest haul of the 30-minute session.

Points leader Shane van Gisbergen led for the balance of the session, and wound up 13th.

The top 20 runners were covered by less than a second.

“Obviously the track is degrading, which is what we expected,” Waters said.

"It was more just how much it was going to degrade.

"Our team did a really good job having a good place for practice.

“Hopefully we can keep moving forward."

The session ran largely incident-free, although James Courtney and Todd Hazelwood made minor contact at Turn 7.

Andre Heimgartner also found the Turn 7 sand after 12 minutes of running.

Van Gisbergen, who has never won in Perth, set the early running with a 54.530s.

The times tumbled in the final three minutes, with Tim Slade firing to the top with a 54.373s.

Waters soared to P1 with his 53-second time, with Le Brocq moving into second on a 54.216s.

De Pasquale, who is making his first Perth appearance as a Shell V-Power Racing Team driver, shot to P2.

David Reynolds and Brodie Kostecki were fourth and fifth ahead of Macauley Jones and Chris Pither.

Kostecki was highest-placed of the seven drivers making their first main game starts in Perth.

Slade, Will Brown and Lee Holdsworth rounded out the top 10.

Cars will return to the track for Practice 2 at 12:15pm local time.
