Falie is a 46-metre (151 ft) ketch that traded for many years in Australian waters. Originally built in 1919 as the motor schooner collier Hollands Trouw, she was purchased by the Spencer's Gulf Transport Company, renamed, and used for coastal trading in South Australia. The vessel was commissioned into the Royal Australian Navy (RAN) as HMAS Falie during World War II, serving first as an inspection vessel primarily patrolling the Port of Sydney, Australia, then as a stores ship.
Returned to her owners in 1946, Falie was used to transport explosives around Australia before resuming the South Australian coastal trade to Kangaroo Island and on occasion carrying bulk gypsum from Stenhouse Bay from 1968. She was retired in 1982, then purchased by the South Australian government for preservation. Although initially used for day and overnight sails, by 2005 the ship had fallen into disrepair.
She was built in Maassluis, Netherlands by W. Richter as a gaff rigged motor schooner in 1919 and named Hollands Trouw. At the time she was built as a speculation by the builder, in the hope of selling her to a prospective buyer. As a result, she sat idle after her launch in 1919 until purchased by Spencer's Gulf Transport Company in 1922.
She was bought by the Spencer's Gulf Transport Company Limited in 1922. In 1923, she sailed to South Australia, where she was renamed Falie and participated in the extensive ketch trade to isolated towns along the coast of South Australia. Later she was converted from her original configuration to a ketch.
During World War II, the Royal Australian Navy requisitioned Falie, renaming her HMAS Falie. Initially she was used as an inspection vessel. On the night of 31 May, she was acting as a watchdog outside Sydney Harbour when she struck a Japanese midget submarine trying to infiltrate the harbour. Falie was converted in 1943 to a stores vessel, and was deployed to Papua New Guinea, where she saw action landing troops in enemy territory by night.
