Van Gisbergen and Winterbottom continued to battle after the safety car returned to the pit lane, but Van Gisbergen was eventually able to build a lead. The safety car was called for the second time on lap 40, when Whincup became stuck in the gravel trap at Turn 4, having run wide following his second pit stop. All of the other drivers came into the pit lane to take on their remaining fuel requirement. Waters' car was taken into the garage with an engine problem which left him several laps off the lead. Shortly after the safety car period ended, Rick Kelly began suffering from brake problems, which slowly worsened and eventually forced him to retire from the race on lap 57. Blanchard retired from the race on lap 74, when his front splitter collapsed under the front of the car and caused him to go off the circuit at Turn 6 and become stuck in a gravel trap. Van Gisbergen looked set to take victory until lap 80, when Waters' car, which had returned to the circuit, suffered an engine failure on the run into Turn 4, depositing large amounts of oil onto the track. Andre Heimgartner and Whincup, immediately behind Waters, both went off the circuit and made heavy contact with each other. Heimgartner was beached in the gravel trap but Whincup was able to continue, while Moffat also spun. Van Gisbergen and Winterbottom both slid on the oil, with Van Gisbergen getting stuck in the gravel trap with his car against the barrier. This allowed Davison and Lowndes through into the top two positions, while Winterbottom recovered and assumed third place. Davison held on to take victory ahead of Lowndes and Winterbottom, with McLaughlin and Mostert completing the top five. Tander and Courtney finished sixth and seventh, having started 18th and 19th respectively. The result saw Davison assume the championship lead ahead of Lowndes and Whincup, while Van Gisbergen dropped to seventh place, having led the points standings after Race 4.
