I named this region Australia Felix, the better to distinguish it from the parched deserts of the interior country where we had wandered so unprofitably and so long.
1851, Henry Saxelby Melville, The Present State of Australia: Including New South Wales, Western Australia, South Australia and New Zealand, page 59,
Victoria, known as Australia Felix, is bounded on the north and north-east by a straight line drawn from Cape How to the nearest source of the Murray River ; on the west by the eastern boundary of South Australia, or the 141° of east longitude, from the River Murray to the sea coast, and along the coast, including the adjacent islands, to Cape How.
