[2] On 25 October, Swan and Warrego sailed to Port Said to meet a troop transport convoy and their Japanese escort, and accompany them to Salonika.

[4][5] After the end of World War I, Swan was assigned to an Allied fleet responsible for taking over Russian anti-Bolshevik naval units as Sebastapol.

She then sailed in December with the French destroyer Bisson to report on conditions in the eastern Ukraine, although they reached their destination, an advance by Bolshevik forces caused the cancellation of the mission.

[2] Swan and sister ship Parramatta were stripped down, and their hulks were sold to New South Wales Penal Department and towed to Cowan Creek, where they were used to house prisoner labourers working on roads along the Hawkesbury River.

[2] Public outcry opposed this use of prison labour, so the two hulks were sold in 1933 for 12 pounds each to George Rhodes of Cowan, New South Wales, who intended to use them as accommodation for fishers.

[6][7] Rhodes' plan did not gain government approval, and the ships were sold on to a pair of fishermen, who used them to transport blue metal to Milson and Peat Islands.

[6][7] The exact location of Swan's wreck was forgotten until 1994 When Greig Berry, a researcher/diver from the Central Coast claimed to have found it in 19 metres of water near Little Wobbie public wharf.

[7] Diving the wreck is not advised, as while Swan sits in only 20 metres (66 ft) of water, the currents in the area flow at around 4 knots (7.4 km/h; 4.6 mph), and visibility is less than 1 inch (25 mm).
