Deeply corrugated and slippery surface very dangerous

Diamond Fields Road Mittagong is off Old South Road Mittagong. The road is deeply corrugated and slippery almost impossible to drive on, even at very low speeds i.e. less than 10 kph. Council and the mayor are aware of the dangerous situation and seem to unwilling to attend to this road.The road has never been so seriously corrugated and almost impossible to drive on. There are approx.30 properties along the road. Most of us have to use /have purchased old vehicles to save the alarming damage and wear and tear to our vehicles. The mayor has seen the road at a meeting and refuses to expedite any serious repairs to the road. it is only a matter of time before someone is injured.We have had to close our cellar door as the road is basically impassable and we are not prepared to compromise visitors safety. Over the past 15 years the road has been occasionally graded, however now it is so corrugated and has deep sided culverts which make passing an on coming vehicle a serious threat to rolling our vehicle. Urgent attention is required and not small patch ups. The mayor and council have been aware of these ever worsening and more dangerous road conditions for over 15 years.
