Not all Australian Wagyu is the same.
The word “Wagyu” alone doesn't tell you how much Wagyu genetics are actually present in the animal. Australian Wagyu can range from first-generation crossbred cattle to F4 Purebred and Fullblood Wagyu.
At Wagyu Steak Company, we believe customers buying premium Wagyu should know what they're getting.
The Australian Wagyu we sell is Master Selection Certified F4 Purebred Wagyu.
And in 2026, Master Selection was named Champion of the Purebred Wagyu class at the Australian Wagyu Association Wagyu Branded Beef Competition.
What Do F1, F2, F3 and F4 Wagyu Mean?
The F classifications describe generations of Wagyu breeding and increasing levels of Wagyu genetics.
F1 Wagyu — 50%+ Wagyu
F1 is the first generation of Wagyu crossbreeding. A common Australian program begins by breeding Fullblood Wagyu with another breed, frequently Angus.
F2 Wagyu — 75%+ Wagyu
Breeding back toward Wagyu genetics increases the Wagyu content to approximately 75% or greater.
F3 Wagyu — 87.5%+ Wagyu
Another generation increases the Wagyu genetic content again, to approximately 87.5% or greater.
F4 Wagyu — 93.75%+ Wagyu
By F4, the animal has greater than 93.75% Wagyu genetic content.
That is a substantial difference from an F1 Wagyu cross.
The Australian Wagyu We Sell Is Certified F4 Purebred
This distinction matters to us.
Master Selection isn't simply marketed as “Australian Wagyu.” Mort & Co identifies Master Selection as Certified F4 Purebred Wagyu.
Master Selection cattle are also grain-fed for a minimum of 400+ days, 100% MSA graded and AUS-MEAT marble scored, with no added hormones.
That gives our customers considerably more information about the beef they're buying than the word “Wagyu” alone.
2026 Purebred Australian Wagyu Champion
In 2026, Master Selection earned an important distinction.
At the Australian Wagyu Association Wagyu Branded Beef Competition, Master Selection by Mort & Co was named:
2026 Class Two Champion — Purebred Wagyu
The competition separates Wagyu into different classes, including Fullblood, Purebred, Crossbred and F1 Wagyu.
In other words, Master Selection was evaluated in the category representing the type of Australian Wagyu we sell — Purebred Wagyu — and won its class.
For us, that's meaningful independent recognition of the product we're proud to offer our customers.
Purebred vs. Crossbred Australian Wagyu
Crossbred Wagyu can produce excellent beef, but the classifications aren't interchangeable.
An F1 Wagyu animal begins at approximately 50% Wagyu genetics. F2 and F3 progressively increase Wagyu content. F4 represents greater than 93.75% Wagyu genetics.
Master Selection goes further and is identified as Certified F4 Purebred Wagyu.
When you're comparing Australian Wagyu products, knowing the classification gives you a much clearer understanding of what you're actually buying.
Is Purebred the Same as Fullblood Wagyu?
No.
Purebred and Fullblood are different Wagyu classifications.
F4 Purebred Wagyu has an extremely high percentage of Wagyu genetics. Fullblood Wagyu has additional pedigree requirements associated with cattle tracing through registered Fullblood Wagyu ancestry without outcrossing to another breed.
Both can produce exceptional beef, but the terms shouldn't be used interchangeably.
Does F4 Tell You the Marbling Score?
No. These measurements tell you two different things.
F4/Purebred describes the genetic classification of the cattle.
BMS describes the level of marbling in the beef.
That's why you may see one of our products described as F4 Purebred Australian Wagyu, BMS 8–10.
The F4 Purebred designation tells you about its Wagyu genetics and classification. The BMS range tells you about the extraordinary marbling of that particular beef.
Genetics, breeding selection, feeding and animal management all contribute to the finished product.
Why Provenance Matters When Buying Wagyu
Premium Wagyu is expensive. We think customers spending that kind of money deserve more information than a beautiful photograph and the word “Wagyu.”
Before buying Australian Wagyu, consider asking:
Where was it raised?
Is it Crossbred, Purebred or Fullblood?
What is its Wagyu genetic classification?
What is its marbling score?
Who produced it?
Can those claims be verified?
Those are questions we're proud to answer.
