But the basketball great says the venue plan is critical, and he hopes the Queensland government gets it right for Brisbane 2032 on Tuesday.
Mr Heal enjoyed four Olympics during his stellar career, but there was one he savoured the most.
At the Sydney 2000 Games, the Australian men's basketball team was denied a historic first Olympic medal by Lithuania in the play-off for bronze.
But Mr Heal only has fond memories.
"It was incredible. I was lucky enough to go to four Olympics," he told AAP.
"But there is nothing compared to having it at home, having the full support of a home crowd at a great venue, like the one we played in the final four.
"That experience is something you never forget."
Mr Heal hopes Australian athletes have the same experience in Brisbane 2032 but believes the infrastructure has to be right.
The Queensland government on Tuesday will finally unveil the Games blueprint following a 100-day review and a number of false starts since Brisbane was named host in July 2021.
A 60,000-seat main stadium will reportedly be built in inner Brisbane's Victoria Park near a new aquatic centre.
However, a planned Commonwealth-backed $2.5 billion Brisbane Arena in the CBD is set to be scrapped along with another major indoor sports centre that was slated to host basketball.
Mr Heal was hopeful Brisbane 2032 would put on a great show, and the likes of basketball were provided a fitting stage.
He said the Australian men's and women's teams had been perennial top-four finishers at the Olympics, and expected basketball to be the "hottest ticket in town" in 2032.
"It's by far the most high-profile team sport at the Olympics," he said.
"It's not just Australia. There's all those NBA guys too.
"And looking at the sport's growth and popularity, you would think they would want the biggest and best facility they possibly can (for Brisbane 2032)."
Mr Heal hoped the 2032 venue plan would provide legacy projects for sports such as basketball in the Queensland capital, where he started his career with the Bullets back in 1988 based at Boondall's Brisbane Entertainment Centre.
"Look at the facilities at Brisbane. Boondall is a bit of a dinosaur," he said.
"I played my first year there in 1988. It was great back then but that was 37 years ago."
