WARNING -- If you come within 10 feet of Ben Simmons, there's a 100% chance he's gonna dunk on your ass ... and some kids in Australia found that out REAL QUICK!!
The NBA superstar attended the Helping Hoops charity basketball event in Melbourne on Tuesday ... and turned it into an absolute dunking CLINIC on the kids in attendance.
The vid is awesome ... Ben dribbles the ball up the court and puts his defender on a poster. The players lost their minds and Simmons playfully taunts his opponent for even jumping to block the inevitable dunk.
