"We absolutely love coming here, the track is insane," he said.
Courtney agreed: "It's awesome," he said. "I couldn't imagine us not racing here.
"It's one of the marquee events of the whole season and it's great to have it here for another three years."
After winning the season-opening Clipsal 500 in Adelaide, Courtney has slumped to 10th in the standings, but is confident of a turnaround at next weekend's Townsville 400.
"It's not as closed-in as the Gold Coast so you tend to take a few more risks," he said.
"It should be some really good, hard, open racing which is what we've had all year really with 10 winners in 13 rounds."
Davison won at Townsville in 2013 and has been on the podium half a dozen times since, knowing another victory would launch him right back in to championship contention.
"It's so close at the moment and I've kept myself in striking distance which is good," he said.
"Changing teams (to Tekno Autosports) we've got a great car and we're just getting stronger and stronger."
