Striploin, also known as Sirloin, New York Strip, or Porterhouse (when bone-in), is a premium cut prized for its bold flavour and balanced tenderness. It comes from the short loin of the cow and features a fine grain with a satisfying bite. It's a favourite among chefs and home cooks alike for its generous marbling and robust, beefy taste.
The Diamantina Wagyu Sirloin Steak offers an indulgent twist on a classic cut. With its generous strip of fat and consistent texture, this SB 8+ sirloin is both easy to cook and incredibly satisfying to eat.
Hand-cut by our in-house butchers, this steak delivers the perfect balance of buttery Wagyu richness and beefy depth. Whether it’s a quick weeknight pan-sear or a special-occasion grill, it’s a steak that rewards simplicity and precision.
This steak is made for high-heat cooking. Try a cast iron pan with minimal seasoning, or fire it over flame for a smoky finish. Let it rest and slice across the grain for a tender, restaurant-style result at home.
This Wagyu sirloin comes from Stanbroke, Australia’s most trusted vertically integrated beef producer. From station to steak, Stanbroke controls every part of the process, ensuring exceptional quality, consistency and care. That’s why Diamantina Wagyu is known for its flavour, tenderness and traceability.
Refined, rich and rewarding, this is Wagyu sirloin, the Peter Augustus way.
