“Shane decided to go in, and I hadn’t heard anything, so I decided the press on.
“Obviously got past the Safety Car and attacked on the in-lap, and I think that was probably what gave me the lead.
“Just a bit of luck, I suppose, to stay out and push that extra lap."
At the time, van Gisbergen led Waters by 1.6s. Waters, Todd Hazelwood and Nick Percat stayed out, and managed to beat the Safety Car itself to the timing line.
Waters was able to complete another lap at full speed before taking his stop and grabbed the lead back.
To gauge how much Waters was pushing on his in-lap, he was just 0.108s slower across the first two sectors of the Reid Park Street Circuit on lap 19, which was under Safety Car conditions, than lap 18.
Van Gisbergen also lost time in his stop, which was 9.2s, some 1.7s slower than Davison’s. Van Gisbergen missed the mark in his pit bay, whereas Davison was bang-on.
Waters, meanwhile, also stopped on the mark and was stationary for 8.1s.
