The state flag of Western Australia made of synthetic and wool bunting with a cotton hoist. It is entirely machine-sewn with a cord for hoisting attached. The flag is blue with a Union Flag in the canton. There is a circular cotton badge in the fly with a black swan on a yellow background. A maker's label is attached inscribed: 'TUDALUX. Another flag from TUDOR HOUSE, 286 Albany Highway, Victoria Park. Telephone 361 1620 [pencil] 6 x 3 WA'. The flag was acquired with items for an America's Cup display.

When the colony of Western Australia first adopted the flag in 1870, the swan faced away from the hoist. As this was felt to be heraldically incorrect, its direction was changed in 1953 when the present design was adopted.
