The Diamantina Wagyu Sirloin Piece is a 2kg portion of fine dining quality beef.
Hand-selected from our SB 4 to 5 marble score range, this cut is known for its balance of tenderness and bold beef flavour, making it ideal for creating perfectly portioned steaks or roasting whole for a luxe centrepiece.
Sourced from Stanbroke’s world-class Wagyu program, this sirloin delivers the kind of melt-in-your-mouth experience only high-grade Wagyu can provide.
Pure Wagyu comes from fullblood or purebred Wagyu genetics (97.75%+ Wagyu), offering the highest potential for marbling, tenderness, and flavour complexity. Unlike crossbred Wagyu, PURE Wagyu delivers the signature melt-in-your-mouth texture, rich buttery flavour, and refined eating experience that sets it apart. This product is 400 days grain finished to maximise marbling and flavour, with no added hormones.
Steak Night: Slice into 250 to 300g steaks, and sear over high heat for a perfect crust and juicy centre. Rest well, and finish with truffle butter, or chimichurri.
Roast Whole: Season simply with salt, and rosemary, then roast at 160°C until internal temperature reaches 52 to 54°C for medium-rare. Rest, and carve thinly for impressive entertaining.
Sous Vide & Sear: Cook sous vide at 54°C for 2 hours, then finish in a hot pan for a luxurious, evenly cooked result.
Keep frozen at or below −18°C.
Thaw under refrigeration (0–4°C) before use.
Do not thaw at room temperature.
Do not refreeze once thawed.
Once thawed, consume within 24–48 hours.
Cook thoroughly before consumption.
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.
All of our beef is from our parent company Stanbroke Beef. This is important as the quality of the beef and ultimately your eating experience is determined by the care that has been shown to the animal during each stage of the production process. Any undue stress the animal experiences at any stage of its life is detrimental to the beef it will produce.
As Stanbroke owns and operates each stage of the production process, strict best practices are followed to ensure the animals always receive the highest of care and that’s why at Peter Augustus we can guarantee the quality of our product each and every time.
The SB Score measures intramuscular fat (the white flecks in the meat). Higher scores mean more marbling, which results in superior tenderness, juiciness, and a richer, buttery flavour.
Vacuum sealing removes air from the packaging, slowing oxidation and bacterial growth to extend freshness and shelf life. When stored correctly at 0–4°C, you can expect the following guide:
For longer storage, keep products frozen at -18°C, where vacuum sealed meat can last 1 to 3 years depending on the cut and consistency of temperature.
Once opened, the shelf life reverts to that of standard fresh products, so we recommend consuming promptly.
For longer delivery routes, some items may arrive partially or fully frozen to ensure they remain within safe temperatures during transit.
Our beef is vacuum sealed to lock in freshness and extend shelf life by removing oxygen. This can cause the meat to appear darker or slightly purplish due to natural myoglobin, which is completely normal.
Once opened, simply let your steak rest out of the packaging for 10 to 20 minutes. As it’s exposed to air, it will “bloom” back to its natural rich red colour. Rest assured, your beef is fresh and perfectly safe to enjoy.
Yes. If the “Use By” date is within range your meat is fresh. Any colour variation from vacuum sealing is normal and will return to its natural red once opened and allowed to bloom.
