One of the great things about being in down under is you get really good wagyu. I have used kobe labeled American wagyu in US before and I have to tell you this is whole different thing. Most American wagyu is a cross bred with Black Angus and genetically they carry %25 pure wagyu genetics. Marbling is better than your black angus but nowhere near the real thing. Also the meat is darker.
Australia being one of the largest exporter of Wagyu beef to Japan , most of the full blood (F4-F3 gets send direct to Japan) F2 (%75 wagyu -%25 holstein or angus ) or F1 (%50 full blood %50 holstein or angus) is common in high end restaurants.
The sirloin in the picture is F2 with Marble grade being 8 (in australia Marbling grade goes to up 9+ , altough the westerners don't like the super pinkish appearence in Japan you can get it up to 12!)
I love processing wagyu , love the beef scraps
