Where Was I Again?

Harry Hutton asks: "Which state is Newcastle in?"

I'm glad you asked, Harry. Last time I checked, Newcastle was in NSW, Australia, and will remain that way for some time, bar revolution, civil war, or peaceful succession from the rest of Australia.
It is therefore easily distinguishable from Newcastle (Western Australia), Newcastle (Wyoming, America), Newcastle (Pennsylvania, America), Newcastle (Washington, America), Newcastle (Delaware, America), Newcastle (New Brunswick, Canada) and Newcastle (Alberta, Canada).

Not to mention Newcastle, England, in whatever Province/ County/ Barony/ Satrap/ Emirate/ Sultanata/ Whatever-it-is-you-call-it-over-there.
