Korringal is private and has not been maintained for a number of years. It is only really suitable for helicopters which use the place for emergency search operations etc.
Last landed there about 10 years ago and it was soft, soft, soft. You would not get a 172 off the ground from this strip.... in fact when we were last there several Jabiru aircraft could not take off with 2 people on board, they have to go back to just the pilot only to have any chance of getting off and a couple of hours with more suitable aircraft would then fairy the passengers to Dunwich where they jump back on the Jabiru and flew off to home
