that the initial plans for the colony were limited. The settlement was to be a self-sufficient penal colony based on subsistence agriculture. Trade, shipping and ship building were banned in order to keep the convicts isolated and so as not to interfere with the trade monopoly of the British East India Company. There was no plan for economic development apart from investigating the possibility of producing raw materials for Britain. Christopher and Maxwell-Stewart argue that whatever the government's original motives were in establishing the colony, by the 1790s it had at least achieved the imperial objective of providing a harbour where vessels could be careened and resupplied. The colony of New South Wales Establishment of the colony: 1788 to 1792 The territory of New South Wales claimed by Britain included all of Australia eastward of the meridian of 135° East. This included more than half of mainland Australia and reflected the line of division between the claims of Spain and Portugal established in the Treaty of Tordesillas in 1494. Watkin Tench subsequently commented in A Narrative of the Expedition to Botany Bay, "By this partition, it may be fairly presumed, that every source of future litigation between the Dutch and us, will be for ever cut off, as the discoveries of English navigators only are comprized in this territory". The claim also included "all the Islands adjacent in the Pacific" between the latitudes of Cape York and the southern tip of Van Diemen's Land (Tasmania). King argues that an unofficial British map published in 1786 (A General Chart of New Holland) showed the possible extend of this claim. In 1817, the British government withdrew the extensive territorial claim over the South Pacific, passing an act specifying that Tahiti, New Zealand and other islands of the South Pacific were not within His Majesty's dominions. However, it is unclear whether the claim ever extended to the current islands of New Zealand. The colony of New South Wales was established with the arrival of the First Fleet of 11 vessels under the command of Captain Arthur Phillip in January 1788. It consisted of more than a thousand settlers, including 778 convicts (192 women and 586 men). A few days after arrival at Botany Bay the fleet moved to the more suitable Port Jackson where a settlement was established at Sydney Cove on 26 January 1788. This date later became Australia's national day, Australia
