About
Diameter is a 2yo brown colt from Australia, trained by Chris Waller in the Gold Coast region. He is by Brazen Beau out of Circular. As a stakes winner with career earnings of $244,750, Diameter is considered an above‑average racehorse. On 11 Apr 2026 at Randwick, Tommy Berry rode him to his biggest victory, capturing the $200,000 Fernhill Hcp over Salann. The horse has consistently delivered profit for bettors, and a career‑long backing would have yielded an 8% return on investment.
