The Peter and Paul Snowden trained colt was third on debut last month and took improvement from that outing to score a length win in the 1100 metre maiden.
A $190,000 Inglis Classic purchase from the Sledmere draft for Snowden Racing, King's Trust was bred by Sledmere and is the first winner from Rose Tinted, an unraced half-sister by Choisir to Group III winner Ready to Attack from Group I winner Gaze.
With 13 individual two year-old winners Hinchinbrook is behind only Spirit of Boom (16), I Am Invincible (15) and Not a Single Doubt (15) and ahead of his three-quarter brother Snitzel (10).
Among Hinchinbrook's two year-old winners is Group I ATC Champagne Stakes winner Seabrook, one of five stakes-winners for the son of Fastnet Rock this season.
Hinchinbrook stands at Yarraman park this spring at a fee of $55,000.
