I feel your pain Craig, my wife & I built over on Kangaroo Island 8 years ago around this time of year and the trucks were constantly getting bogged in the driveway, the concrete guys had to wheel barrow 90mtrs down to our stables over wooden planks (12m3) of concrete because the pump broke down etc etc etc.. But we had no choice because we had sold our house on the mainland and had to move over by a given dead line - never again if I can help it though..
