Here's what I was looking for:
Australian Term: Scotch Fillet
U.S.A. Term: Ribeye Fillet (Ribeye steak without bone)
Thank you Haggis and Foodaholic for distilling the answer I was looking for. Everyone else, thanks for your input!
The problem with searching an Aussie website for recipes (if you live in Texas) is that you need to translate the terms used in some cases.
