SS Ayrfield (originally launched as SS Corrimal) was a steel-hulled, single screw, steam collier of 1140 tonnes and 79.1m in length. It was built in the UK in 1911 and registered at Sydney in 1912. It was purchased by the Commonwealth Government and used to transport supplies to American troops stationed in the Pacific region during WWII.
In 1950, it was sold to Bitumen and Oil Refineries Australia Pty Ltd and in 1951 sold to the Miller Steamship Company Ltd and renamed Ayrfield. Under the Miller flag, it operated as a collier between Newcastle and Miller’s terminal in Blackwattle Bay.
The registration of Ayrfield was cancelled on 6 October 1972 and the old collier sent to Homebush Bay for breaking-up. The hull is located near the mouth of Haslams Creek with the bow pointing towards the shore.
