The West Australian flag was blue with a yellow disc bearing a black swan swimming towards the fly on a representation of water. Lloyds, Reed and Brown show a somewhat smaller disc than Loughran. The Log’s version, W365, has the swan facing the hoist without water lines; Rosanoski doubts this in view of the contemporary Western Australian emblem. The swan originally appeared on the funnel too, its colour unspecified; about 1910 the funnel changed to black with two white bands.
West Australian Steam Navigation Co., also called Western Australia Steam Navigation Co. in some sources, began in 1886 as a steamer service formed by Trinder, Anderson & Co., Charles Bethell & Co. and Australian shipping agents for the Fremantle–Singapore trade. Charles Bethell’s firm became Bethell, Gwyn & Co. in 1892. West Australian continued trading until 1935 or 1936 according to differing accounts.
Rosanoski rejects a claim that Ocean Steamship owned Australind, suggesting confusion with a joint service between Blue Funnel and West Australian Steam Navigation. Charon, built in 1903 for the Singapore–Batavia–Fremantle service, flew both companies’ flags. A second Charon was built in 1936 for the joint venture, from which West Australian withdrew shortly after service began.
