It's known as gyproc up here... and since we have the gypsum mines

Mate, Gyproc is a trademark of an Australian sheetrock manufacturer.

Yes, and Sheetrock is the trademark of a US manufacturer of gypsum

It's one of those trademarks that has slipped into general usage.

I had a 1939 book on how to drive tunnels. It referred to the common
90 pound vertical drilling hammer as a JackHammerTM [Ingersoll Rand],
