I've not seen that for years. I wonder why. Morrisons sold a lot of Australian steak when BSE was a big thing, but since then it's always been British.
My grandma used to love the Australian beef from Morrisons in the 1990s as it was more beefy. She had twenty of us round every Friday for crop and inlift with the full works. Crop is what they used to call a forerib of beef in Yorkshire, and inlift is topisde. She also used to call fillet steak 'undercut'.
