The entry fee of $35 per team - increasing to $50 on the day - will go towards paying the way of players selected for the 3x3 Youth Olympics in Nanjing, China, and the 3x3 World Championships in Moscow, Russia.
The action will include under-14, under-16, under-18 and open grades for men and women, though since the competition is based on FIBA rules, there will not be mixed grades.
Players supply their own uniforms, though bibs will be available.
The action in The Strand car park on Saturday tips off at 10am.
