Jongkuch Mach is just 17-years-old and already 7'6" — 228.6cm.

The Australian-South Sudanese centre plays for the Centre of Excellence (CoE) in the NBL1 East Men's Conference and is already attracting global attention despite limited minutes for the Canberra-based Australian Institute of Sport basketball player.

"Standing at an absurd 7'6" at just 17 years old, Australian-South Sudanese big man Jongkuch Mach may be the most intriguing prospect in the world currently," wrote NBA Draft analyst Nick Kalinowski on Twitter.

"The absurdly tall Mach is extremely mobile for a player his size, able to get up the court with ease & dunk without jumping."

Mach is just 3cm shorter than the two tallest players in NBA history — Gheorghe Mureșan and Manute Bol — and taller than Australian 2025 NBA Draft pick Rocco Zikarsky.

Mach's potential upside is extreme. He's played just 120 minutes in 11 games this season for CoE.

Best Game (statistically) — June 21st, 2025

• 19:33 minutes
• 3-from-3 FG (100%) and 1/2 FT (50%)
• Seven rebounds
• Two blocks
• Nine points

But it's Mach's Per 36 minutes breakdown based on his 2025 averages that US college and professional scouts will be studying and drooling over.

• 14 PPG
• 14 RPG
• 4.5 BPG
• 2.4 SPG

Four and a half blocks per game and 14 boards for a player who can dunk the ball without jumping. Even more tantalising is Mach is mobile, although yet to grow into his extraordinarily tall body.
