We saw this at Lawrence when we were going to buy fruit, taking much the same route as the goldminers and pioneers of old took. This is the way we travel up to our caravan.
Our first stop is at a little place called Lawrence, not far from where Gabriel Read first discovered gold and started one of the biggest gold rushes in the southern hemisphere in the early 1860's. It lured men from all over the Australian and Californian goldfields.
I don't know but am guessing that the water cannon was used to sluice the hillsides when mining for gold.
A&T Burt were the manufaturers and were established in 1862. but sadly not still operating.
