The 500-ton Oil Fuel Lighter was a class of oil fuel lighters built for the Royal Australian Navy between 1913 and 1916.
[1] The lighters were 156 feet (48 m) in length, 14 feet (4.3 m) depth and 30 feet (9.1 m) breadth and cost about £18,000 each to build.
[2] The hull included 10 oil tanks, separated by air spaces and cofferdams, which held a capacity of 550 tons of liquid fuel oil.
[2] Sleeping accommodation and a saloon were also provided in the forward portion.
Two sets of diesel engines with centrifugal pumps discharged the fuel oil from the tanks.
