A seven-time grand prix winner, 29-year-old Ricciardo has plenty of seasons in F1 ahead of him, and says racing at Bathurst beyond that is not off the cards.
"I got asked not long ago 'after F1 would you want to do some races, do something else like V8s or NASCAR or Le Mans?'," Ricciardo said.
"When I first got into F1 a few years ago, I was like 'yeah, that'd be awesome, I'd love to'.
"But the more years I do this, it kind of wears you out. And I thought 'once I'm done [in F1], I think I'll be done [with driving]'.
"I'm probably kidding myself, because driving that, [Bathurst] would be pretty cool. I'll never say never.
"I'd give it a good 50-50 at the moment."
Supercars' trip to Mount Panorama routinely clashes with the Japanese Grand Prix, and instances of drivers branching out during their F1 careers are rare.
Fernando Alonso is an exception, having contested the Indy 500 and won the Le Mans 24 Hour during his McLaren stint that concluded last season.
