Just a bunch of farmers of whom happen to be in the CFA using what power they have to stop the government/utility company putting above ground power poles and wires through their property to carry solar power. As I understand it, they have no objection to solar/renewables, but putting ugly high-tension towers through their beautiful countryside is a pole too far. So really nothing to do with renewables and everything to do about destruction of farmland, forests (prime koala habitat) and of course a depreciation of farm property values.
