Was Australia one of the colonies of Great Britain in the War of 1812?

Answer 1

Yes, the Crown Colony of New South Wales, according to Arthur Phillip's amended Commission dated 25 April 1787, includes "all the islands adjacent in the Pacific Ocean" and running westward to the 135th meridian east. This included the islands of New Zealand. When drawing up the territorial boundaries of the colony of New South Wales, established in 1788, the British government set its western boundary at the meridian of 135º East of Greenwich, as it appeared on Melchisédech Thévenot's chart, Hollandia Nova‒‒Terre Australe, published in Relations de Divers Voyages Curieux (Paris, 1663).
