NBA legend Paul Pierce has watched enough rugby league to know it's a "gruelling" and "intense" sport.

The Boston Celtics great is heading to Australia for the first time next month on his "You're A Legend Tour" and will stop by ANZ Stadium on October 6 for the NRL grand final.

The NRL and NBA have teamed up to give two lucky fans the chance to meet Pierce and league champion Johnathan Thurston pre-match before watching the action from corporate hospitality.

"From what I hear it's one of the biggest times of the year," Pierce told former NRL star and Celtics fanatic Jamie Soward.

"… I have a couple of friends that played rugby [league]. It's a very physical and gruelling sport. You've gotta have a pretty big heart to play.

"Us in America, we play football but they use pads and helmets. Rugby [league] is a different animal because there's no pads, there's no real helmets. It's just pretty much all physical contact and athleticism.

"It's pretty intense, I'mma say that."

Pierce is also set to attend the NRL Fan Fest on Friday, October 4 in Sydney's Martin Place.

After a 19-year NBA career – including winning the 2008 championship and Finals MVP award – Pierce understands what it takes to reach the top better than most.

The 10-time All-Star is looking forward to meeting Cowboys hero Thurston, who exuded excellence during his incredible NRL career.

"When I hang around sports players who have achieved the ultimate goal of being a champion, I think the common thing is their passion for the sport, their competitive drive and the sacrifice," Pierce said.

"A lot of people see championship players on the stage but they don’t see the time and the hours you put in getting ready."
