Cook came westward, across the Pacific, with an expedition in 1769, to observe the Transit of Venus at Tahiti, and then sailed 8 south-west to New Zealand. He sighted land at Poverty Bay and sailed south as far as Cape Turnagain; then he went right round the North Island and through Cook Strait, until the Cape was again sighted, scattering English names and charting the coast as he passed. Next he circumnavigated the South Island, steering outside Stewart Island, which he imagined to be a peninsula; and so to Cape Farewell, in the north-west corner of South Island. He had obtained a fairly accurate idea of the nature of the coast, and had proved that New Zealand was not connected with the supposed Antarctic continent. From Cape Farewell he struck westward, and sighted the mainland of Australia at Point Hicks, on April 19th, 1770, but failed to discover Bass Strait. From Point Hicks Cook sailed along the whole of the east coast to Cape York, giving to the bays and capes as he passed them the names of his crew, of British admirals, officials and politicians of all kinds at home. At various landing places he came into collision with the aborigines, and at Endeavour River he stayed for two months to repair his vessel which had been damaged through striking on the rocks. Finally, before sailing westward through Torres Strait, he landed on Possession Island and formally claimed the whole region discovered for the British Crown. When, in 1798, Flinders and Bass proved that Van Diemen’s Land was an island, the rough work of discovery was complete. Australia, New Zealand and many of the smaller islands were known and charted, and the discoveries of the Spaniards and Dutch were linked up, by the aid of a great deal of miscellaneous exploration carried out by the French navigators who followed us in the South of Australia, in New Zealand, and in the islands of the Pacific. The navigators, French and English, were in the habit of formally annexing the country wherever they landed; but annexation of this kind was of little value without effective occupation. This was to come later, during the course of the next half century. From 1800 onwards, we may say that the different parts of this vast region begin to have a separate and individual history and development, though behind all are the conditions common to most of the area, conditions which distinguish it sharply from the rest of the world even to-day, in spite of minor differences between its separate parts. There is ample room for variation, since the continent of Australia is about three-quarters the size of Europe, or seven times the area of Germany and France together; and it includes nearly every type of temperate and tropical climate.
