Asked if there were international races he'd always eyed, Tander joked fellow retiree Craig Lowndes had likely got a head start on securing drives.
"There are other races, but there's another Australian bloke who's said he wants to do the same thing, called Lowndes," Tander added.
"He's probably beaten me to all of the best drives that are available!
"Realistically, I'll look at what's available after the 12 Hour, do as good of a job as we can there and that'll certainly help open some doors internationally."
Lowndes has set his sights on contesting the Le Mans 24 Hours, which traditionally clashes with the Hidden Valley Supercars event.
Tander indicated the Spa 24 Hours, one of GT3 racing's blue-ribband events, was a more likely target, even if Audi's abundance of drivers might negate that factory link.
"Le Mans is hard to get to these days," he said.
"I think the Spa 24 Hours would be a fantastic race to go and do, that would be my focus if we were going to do anything internationally.
"It's hard, I know through my relationship with Audi that they've got a lot of drivers on their books in Europe that they need to find seats for, so to find a seat for a guy they use once-a-year in the 12 Hour is hard.
"I'll push and see what we can do, but even now it's all pretty late in the piece."
In recent years, Tander has contested a handful of Australian GT races with the Melbourne Performance Centre's Audi program, including winning the 2018 finale with Geoff Emery.
