Speaking after the race, van Gisbergen was grateful for the support he's received during his recovery.
"I had so much help the last couple of weeks with good surgeons, the hyperbaric chambers, nice girlfriend looking after me, our physio," he said. "It's been a pretty tough two weeks but I feel awesome in the car and obviously my car's great. Hopefully that was a good show to watch. I was trying."
While admitting the pain from his brutal injury was still there, he said he's determined to keep driving.
"I didn't know how good I was going to be over a distance. My pain's no worse than it is. I should be alright tomorrow.
"It hurts but I'm not damaging it by driving so yeah try again tomorrow."
It was his 43rd career victory and extends his Championship lead over Chaz Mostert who started from pole position.
Mostert led late in the race but a poor start in the end meant he ran out of steam to finish sixth. He retains second in the Supercars Championship, but is now 60 points behind a still unbeaten van Gisbergen.
The race itself was a see-saw affair with Mostert and Waters leading for the majority of the race until the fast-finishing van Gisbergen, who pitted later than anyone else in the race to try and finish with fast tyres, flew past everyone over the dying laps to claim the lead on the final lap and drive to victory from there.
There will be two further races on Saturday.
