Salt Ash is a rural suburb of the Port Stephens local government areas in the Hunter Region of New South Wales, Australia. It is located on the main road between Newcastle and Nelson Bay but is largely undeveloped, partly because it is the location of the Salt Ash Air Weapons Range which is used by pilots from RAAF Base Williamtown for training purposes. The southern border of Salt Ash is occupied entirely by Stockton Beach. There is a co-ed government primary school called Salt Ash Public School located on 4 Salt Ash Avenue.
