In Australia porterhouse bone-in is the sirloin on the bone.
Porterhouse steaks are T-bones, but a T-bone isn’t a porterhouse. Both cuts both come from the short lion region of the cow and feature the distinctively shaped bone. The difference? It all comes down to the width of the filet.
A porterhouse on the bone has a big juicy sirloin on one side, and a filet on the other side that is at least 1.25 inches (3.2cm) wide. If that filet is smaller than 1.25 inches, it is just a regular T-bone.
