Marion Bay relies on the local desalination plant for town water, other areas just seem to have tank water. Bores are everywhere but many are salty and unsuitable for drinking. The soils are supposedly quite fertile, but are littered with rocks. Virtually every paddock has a pile of rocks along the fence line, under trees or in a low lying area. I am not sure how they are collected, but it looks like there is a machine that picks them up and dumps them.
