After 20 years of dedicated genetic selection and scientific validation, Australian producers have achieved what the global meat industry once considered impossible: red meat with a source-level long-chain omega-3 profile, a revolutionary fat composition that melts below body temperature.
Margra Lamb, co-founded by Graham Gilmore and Tim Leahy in regional New South Wales, has been validated through seven peer-reviewed studies. The breakthrough has already captured global attention. Qantas has served Margra exclusively in its First and Business Class cabins for the past two and a half years and will now feature a documentary about the product’s development on its in-flight entertainment system, and, most recently, in the May edition of its in-flight magazine.
“This isn’t just about creating premium lamb; it’s about re-imagining what red meat can be,” says Graham Gilmore, who pioneered the breeding program with his late brother Martin. “We’ve proven that through careful genetic selection, not modification, we can create meat that’s both healthier and delivers a superior eating experience.”
The innovation centres on three scientifically proven advantages that differentiate Margra from conventional lamb. Its fat melts at 28–35 °C (82–95 °F), compared with over 40 °C (104 °F) in conventional meat, creating an unprecedented “melt-in-the-mouth” texture. The fine micro-marbling perfectly aligns with consumer preferences for tenderness. Most remarkably, its omega-3 levels are three to four times higher than those found in conventional red meat.
Professor Aduli Malau-Aduli, whose research validated Margra’s unique properties, notes that in three decades of meat science, he has never encountered a product like it. “The omega-3 levels and fat composition are unprecedented in mammalian meat,” he confirms.
The product has achieved rapid international adoption, with acclaimed restaurants in Singapore, the Philippines, Los Angeles, New York, and major U.S. cities now featuring Margra on their menus. This global footprint was achieved entirely through chef demand rather than traditional marketing, demonstrating the product’s ability to transcend cultural and culinary boundaries.
Leading Australian chef Mark Best, who appears in the documentary, describes Margra as “an entirely new paradigm in meat.” His blind-tasting experience, captured on film, shows the moment of revelation when he realised he was experiencing something unprecedented in his culinary career.
“The fat quality in your mouth, that low melting point, was immediately apparent. It was almost like hot olive oil when you ate it,” Best explains.
The documentary tells the poignant story of the Gilmore brothers’ 15-year journey. It captures the scientific breakthroughs, multiple failures, and ultimate vindication, including the tragedy of Martin Gilmore’s sudden passing seven years ago while on the phone with Graham. Martin died, never seeing their innovation served at 40,000 feet or in the world’s finest restaurants.
Joel Bickford, Group Culinary Director of The Point Group, confirms the product’s revolutionary status.
“In 34 years of professional cooking, Margra is at the forefront of not just lamb, but of all produce being put forward in the market at the moment.”
The innovation also addresses industry sustainability challenges. The Tattykeel Australian White sheep, from which Margra is derived, requires no shearing or chemical treatments, reducing production costs. The unique fat profile has also enabled entirely new product categories, including lamb prosciutto and salami produced without pork fat, opening the product to a broader global consumer base that does not eat pork. This economic model, a premium product with lower production costs and expanded market reach, represents a new paradigm in agricultural innovation.
The timing of Margra’s global expansion is particularly significant as the premium red-meat market, valued in the hundreds of billions globally, seeks genuine innovation beyond traditional breeding. Margra represents a new chapter for Australian agriculture, proof that science, sustainability, and eating quality can coexist in a single breed. Through decades of disciplined genetic refinement and validation, Margra demonstrates how traditional farming can continue to evolve and lead in a world demanding both performance and provenance.
Tim Leahy, Co-Founder, Margra Lamb, reflects on the journey:
“Martin and Graham’s vision was always bigger than a single farm or family. What they created was a blueprint for how science and provenance can work hand in hand to redefine an entire category. As we share this story with Qantas customers and chefs around the world, we’re not just celebrating what’s been achieved, we’re opening the next chapter in the future of red meat.”
The company expects continued expansion through 2026, with interest from additional international markets and premium food-service providers. The combination of scientific validation, proven performance at altitude and chef-driven global demand positions Margra as the new benchmark for premium red meat worldwide.
