I think it is under heritage order now. I looked for it last time I was there; maybe it's covered up ready for restoration?

It's actually a topographical map of the whole Sydney basin.

Awesome local history, thanks. I vaguely recall seeing it myself.

Another page on that site mentions Eben Gowrie Waterhouse OBE CMG (1881–1977) ... while he is known for Camellia cultivation my research suggests he met with Mussolini and the Japanese government around war time and was a bit of a fascist. They don't mention that bit.

Huh, your mention of camellias immediately (to me) suggested Eryldene.

And sure enough: https://www.eryldene.org.au/
