Early life and naval career
Then, in October 1786, Phillip was appointed captain of HMS Sirius and appointed Governor-designate of New South Wales, the proposed British penal colony on the east coast of Australia, by Lord Sydney, the Home Secretary. His choice may have been strongly influenced by George Rose, Under-Secretary of the Treasury and a neighbour of Phillip in Hampshire who would have known of Phillip's farming experience.
Phillip had a very difficult time assembling the fleet which was to make the eight-month sea voyage to Australia. Everything a new colony might need had to be taken, since Phillip had no real idea of what he might find when he got there. There were few funds available for equipping the expedition. His suggestion that people with experience in farming, building and crafts be included was rejected. Most of the 1778 convicts were petty thieves from the London slums. Phillip was accompanied by a contingent of marines and a handful of other officers who were to administer the colony.
The First Fleet, of 11 ships, set sail on 13 May 1787. The leading ship reached Botany Bay on 18 January 1788. Phillip soon decided that this site, chosen on the recommendation of Sir Joseph Banks, who had accompanied James Cook in 1770, was not suitable, since it offered no secure anchorage and had no reliable water source. After some exploration Phillip decided to go on to Port Jackson, and on 26 January the marines and convicts were landed at Sydney Cove, which Phillip named after Lord Sydney.
Shortly after establishing the settlement at Port Jackson, on the 15th February 1788, Phillip sent Lieutenant Philip Gidley King with 8 free men and a number of convicts to establish the second British colony in the Pacific at Norfolk Island. This was partly in response to a perceived threat of losing Norfolk Island to the French and partly to establish an alternative food source for the new colony.
The early days of the settlement were chaotic and difficult. With limited supplies, the cultivation of food was imperative, but the soils around Sydney were poor, the climate was unfamiliar, and moreover very few of the convicts had any knowledge of agriculture. Farming tools were scarce and the convicts were unwilling farm labourers. The colony was on the verge of outright starvation for an extended period. The marines, poorly disciplined themselves in many cases, were not interested in convict discipline. Almost at once, therefore, Phillip had to appoint overseers from among the ranks of the convicts to get the others working. This was the beginning of the process of convict emancipation which was to culminate in the reforms of Lachlan Macquarie after 1811.
Phillip showed in other ways that he recognised that New South Wales could not be run simply as a prison camp. Lord Sydney, often criticised as an ineffectual incompetent, had made one fundamental decision about the settlement that was to influence it from the start. Instead of just establishing it as a military prison, he provided for a civil administration, with courts of law. Two convicts, Henry and Susannah Kable, sought to sue Duncan Sinclair, the captain of Alexander, for stealing their possessions during the voyage. Convicts in Britain had no right to sue, and Sinclair had boasted that he could not be sued by them. Someone in Government obviously had a quiet word in Kable's ear, as when the court met and Sinclair challenged the prosecution on the ground that the Kables were felons, the court required him to prove it. As all the convict records had been left behind in England, he could not do so, and the court ordered the captain to make restitution. Phillip had said before leaving England: "In a new country there will be no slavery and hence no slaves," and he meant what he said. Nevertheless, Phillip believed in discipline, and floggings and hangings were commonplace, although Philip commuted many death sentences.
Phillip also had to adopt a policy towards the Eora Aboriginal people, who lived around the waters of Sydney Harbour. Phillip ordered that they must be well-treated, and that anyone killing Aboriginal people would be hanged. Phillip befriended an Eora man called Bennelong, and later took him to England. On the beach at Manly, a misunderstanding arose and Phillip was speared in the shoulder: but he ordered his men not to retaliate. Phillip went some way towards winning the trust of the Eora, although the settlers were at all times treated extremely warily. Soon, smallpox and other European-introduced epidemics ravaged the Eora population.
The Governor's main problem was with his own military officers, who wanted large grants of land, which Phillip had not been authorised to grant. The officers were expected to grow food, but they considered this beneath them. As a result scurvy broke out, and in October 1788 Phillip had to send Sirius to Cape Town for supplies, and strict rationing was introduced, with thefts of food punished by hanging.

Governor of New South Wales
By 1790 the situation had stabilised. The population of about 2,000 was adequately housed and fresh food was being grown. Phillip assigned a convict, James Ruse, land at Rose Hill (now Parramatta) to establish proper farming, and when Ruse succeeded he received the first land grant in the colony. Other convicts followed his example. Sirius was wrecked in March 1790 at the satellite settlement of Norfolk Island, depriving Phillip of vital supplies. In June 1790 the Second Fleet arrived with hundreds more convicts, most of them too sick to work.
By December 1790 Phillip was ready to return to England, but the colony had largely been forgotten in London and no instructions reached him, so he carried on. In 1791 he was advised that the government would send out two convoys of convicts annually, plus adequate supplies. But July, when the vessels of the Third Fleet began to arrive, with 2,000 more convicts, food again ran short, and he had to send a ship to Calcutta for supplies.
By 1792 the colony was well-established, though Sydney remained an unplanned huddle of wooden huts and tents. The whaling industry was established, ships were visiting Sydney to trade, and convicts whose sentences had expired were taking up farming. John Macarthur and other officers were importing sheep and beginning to grow wool. The colony was still very short of skilled farmers, craftsmen and tradesmen, and the convicts continued to work as little as possible, even though they were working mainly to grow their own food.
In late 1792 Phillip, whose health was suffering from the poor diet, at last received permission to leave, and on 11 December 1792 he sailed in the ship Atlantic, taking with him Bennelong and many specimens of plants and animals. The European population of New South Wales at his departure was 4,221, of whom 3,099 were convicts. The early years of the colony had been years of struggle and hardship, but the worst was over, and there were no further famines in New South Wales. Phillip arrived in London in May 1793. He tendered his formal resignation and was granted a pension of £500 a year.

Stabilising the colony
Phillip's wife, Margaret, had died in 1792. In 1794 he married Isabella Whitehead, and lived for a time at Bath. His health gradually recovered and in 1796 he went back to sea, holding a series of commands and responsible posts in the wars against the French. In January 1799 he became a Rear-Admiral. In 1805, aged 67, he retired from the Navy with the rank of Admiral of the Blue, and spent most of the rest of his life at Bath. He continued to correspond with friends in New South Wales and to promote the colony's interests with government officials. He died in Bath in 1814.
Phillip was buried in St Nicholas's Church, Bathampton. Forgotten for many years, the grave was discovered in 1897 and the Premier of New South Wales, Sir Henry Parkes, had it restored. A monument to Phillip in Bath Abbey Church was unveiled in 1937. Another was unveiled at St Mildred's Church, Bread St, London, in 1932; that church was destroyed in the London Blitz in 1940, but the principal elements of the monument were re-erected at the west end of Watling Street, near Saint Paul's Cathedral, in 1968. There is a statue of him in the Botanic Gardens, Sydney. There is an excellent portrait in the National Portrait Gallery, London. His name is commemorated in Australia by Port Phillip, Phillip Island (Victoria), Phillip Island (Norfolk Island) and many streets, parks and schools.
Percival Alan Serle wrote of Phillip in the Dictionary of Australian Biography: "Steadfast in mind, modest, without self seeking, Phillip had imagination enough to conceive what the settlement might become, and the common sense to realize what at the moment was possible and expedient. When almost everyone was complaining he never himself complained, when all feared disaster he could still hopefully go on with his work. He was sent out to found a convict settlement, he laid the foundations of a great dominion."

Later life
In 2007, Geoffrey Robertson QC revealed that Phillip's remains are no longer in in St Nicholas Church, Bathampton and have been lost: "...Captain Arthur Phillip is not where the ledger stone says he is: it may be that he is buried somewhere outside, it may simply be that he is simply lost. But he is not where Australians have been led to believe that he now lies." Robertson also believes it was a "disgraceful slur" on Phillip's legacy that he wasn't buried in one of England's great cathedrals and was relegated to a small village church. Robertson is campaigning for a rigorous search for the remains, which he believes should be re-interred in Australia.
"The moral of this story is that we can't trust the English, the Church of England, the British, to look after our national treasures. If we're going to treasure them and remember them properly, we have to do it ourselves."
