By the early 1920's vehicular traffic across the harbour had increased to such an extent that Sydney Ferries Limited decided to order three big car ferries. These were Koondooloo, Kalang and Kooroongabba. The three vessels were broadly similar and all were built in England and travelled to Australia under their own steam.

Koondooloo had a varied career after the opening of the Sydney Harbour Bridge in 1932 prematurely retired the fleet of vehicular ferries. Like Kalang, Sydney Ferries Ltd used her as a cargo vessel from 1932 until 1937. She was converted into the Showboat in 1937 and operated in this guise until 1942. In that year she was requisitioned by the Australian Army. The army coverted her into a repair ship and she was renamed to "S 181". She was towed to New Guinea in 1942 and remained there until 1946.

After being towed back to Sydney in 1946 she was returned back to Sydney Ferries Ltd. They converted her back into a showboat until she was sold off in 1951 to the  Commissioner for Main Roads. Once agaqin she was converted - this time back to her original form as a vehicular ferry. From 1951 until 1971 she was used in this role at Newcastle.

Along with Kalang, Kooroongaba & Lugurena she was sold to Phillipine interests and set out under two to that country in January of 1972.  She foundered at Trial Bay on the NSW north coast on January 9th. Her remains are still there.
