Interesting about the St Ives showground map. Where is it exactly? They have a nice orchid show. Usually it seems to be mostly a bunch of HK dudes playing with RC cars.
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.
It's actually a topographical map of the whole Sydney basin.

[edit: Seems to be where the RC cars race!]
