Doesn't look like a bad pond mate from what I can see (Google Earth doesn't quite go there). Went down to Cronulla from Gladesville in Sydney (when I was working in NSW around 1972) to drop something off to the aunty of a girl in NZ . Remember going down a main road and it ended in a loop round a shopping center. Found the house but got a bit lost on the way back as it was getting dark, and ended up going back over a big high causeway over the water (maybe Princess Highway) never been able to figure it out. It seemed to be really long and following a bay on the coast? may have just seemed that way at night.
You guys have a much better modelling scene in Oz than we have here, seems to be dying a slow death here, (probably lack of area)
