The strip steak, also called a New York strip or a Kansas City strip steak (USA), or a sirloin steak (AU/NZ), is a cut of beef steaks from the short loin.

History of sirloin steak
The word Sirloin derives from the French term “surlonge” — sur for 'above' and longe for 'loin'.
The rib eye steak is one of the most beloved, flavourful, and tender cuts of beef both here in Australia and around the world. It is also known as the rib fillet or the scotch fillet steak, depending on where you go.
The top sirloin is the most prized of these and is specifically marked for sale under that name. The bottom sirloin, which is less tender and much larger, is typically marked for sale simply as "sirloin steak". The bottom sirloin, in turn, connects to the sirloin tip roast.
A sirloin is a piece of beef which is cut from the bottom and side parts of a cow's back.
Porterhouse steak is expensive because it requires a large portion of the cow to be dedicated to a single steak, thus you typically only have one porterhouse steak per animal.
The scotch fillet and sirloin (aka porterhouse), coming from the region near the backbone, fit the bill here perfectly. Even more tender is the eye fillet (or tenderloin). The rump, from the inside of the leg, is more active, but while it might not be quite as tender, it is often well priced.

In British usage, followed in the Commonwealth countries, "porterhouse" often means a British sirloin steak (i.e. US strip steak) on the bone, i.e. without the tenderloin on the other side of T-bone. Some British on-line butchers also offer American style porterhouse steaks.
The most generally accepted tale about how the porterhouse steak got its name is that the proprietor of a New York porter (dark-brown beer) and ale house in the 1800s satisfied an overflow crowd by cutting through a sirloin roast to produce steaks.
"Sirloin steaks are a great budget-friendly option chock-full of flavor," said Jerome, who also suggests cutting sirloin steaks into smaller pieces for another budget-stretching, grill preparation: kabobs. "Top sirloin steaks are a great option to have something lean but also tender and flavorful for your beef kabobs."
As far as taste and texture, top sirloin has a reputation for being tough and chewy. But that's often down to errors in prep and cooking. Because top sirloin is comparatively lean and tends to be sold as a thicker cut, it needs a little extra TLC.
The rib eye is a cut from the rib section and is the most flavorful cut of meat and typically comes with very deep marbling. Because of the deep marbling on the rib eye, it is a great cut for grilling and slow roasting.
