Playing up an age group against the country's best, Mac posted a double-double-adjacent line on 61.2% shooting, with eight rebounds and two blocks a night. Efficiency and rim protection at that rate, as a bottom-ager, is the profile that travels to every level above it.

Player Profile

A Different Kind Of Big

  • Nationally recognized defensive anchor, best defender at the 2025 U16 Nationals
  • Legitimate 6'9" frame in the Class of 2029, still growing
  • Rim protector with the mobility to guard in space: 2.0 blocks per game at U18 Nationals
  • Called one of the best bigs in his age group out of Queensland
  • High-motor Center who impacts winning without needing the ball
  • 61.2% from the field at the 2026 U18 Nationals as a bottom-ager

Every good team is built around a defensive anchor, and Mac Seebeck has already proven he can be one at the national level. At the 2025 U16 National Championships in Bendigo, with the best juniors from every state on the floor, Basketball Australia named him Defensive Player of the Tournament.

At a legitimate 6'9" in the Class of 2029, Mac protects the rim, rebounds his position, and moves well enough to survive on the perimeter, the profile every modern program wants in a young big. Queensland recognized it with state selection, and national media has called him one of the best bigs in his age group.

He backed it up at the 2026 U18 Nationals, playing up an age group and posting 11.1 points, 8.0 rebounds, and 2.0 blocks on 61.2% shooting. Next stop: Iowa United Prep in the United States.

Bigs develop late and the great ones defend first. Mac is already ahead on both counts.
