In 1859 Queensland was severed from New South Wales by Letters Patent issued to Sir George Bowen, the boundaries being given as follows:--"So much of the said colony of New South Wales as lies northward of a line commencing on the sea coast at Point Danger, in latitude about 28 degrees 8 minutes south, and following the range thence which divides the waters of the Tweed, Richmond, and Clarence Rivers from those of the Logan and Brisbane Rivers, westerly, to the Great Dividing Range between the waters falling to the east coast and those of the River Murray; following the Great Dividing Range southerly to the range dividing the waters of Tenterfield Creek from those of the main head of the Dumaresq River; following that range westerly to the Dumaresq River; and following that river (which is locally known as the Severn) downward to its confluence with the Macintyre River; thence following the Macintyre River (which lower down becomes the Barwan) downward to the 29th parallel of south latitude; and following that parallel westerly to the 141st meridian of east longitude, which is the eastern boundary of South Australia; together with all and every the adjacent islands, their members and appurtenances, in the Pacific Ocean; and do by these presents separate from our said colony of New South Wales and erect the said territory so described into a separate colony to be called the 'Colony of Queensland.'" ANNEXATION TO QUEENSLAND, 1862 (MAP 10). On 12th April, 1862, the Duke of Newcastle advised Governor Bowen that Letters Patent, of which a copy was enclosed, had been issued annexing to Queensland the following territory--namely, "so much of our colony of New South Wales as lies to the northward of the 21st parallel of south latitude, and between the 141st and 138th meridians of east longitude, together with all and every the adjacent islands, their members and appurtenances in the Gulf of Carpentaria." The area thus annexed added to Queensland about 120,000 square miles of territory, which now comprises such centres as Birdsville, Boulia, Cloncurry, Camooweal, and Burketown. ANNEXATION TO SOUTH AUSTRALIA (MAP 11). An Imperial Act of 1861 enacted that "so much of the colony of New South Wales, being to the south of the 26th degree of south latitude, as lies between the western boundary of South Australia and 129 degrees east longitude, shall be and the same is hereby detached from the colony of New South Wales and annexed to the colony of South Australia, and shall for all purposes whatever be deemed to be part of the last-mentioned colony from the day in which the Act of Parliament is proclaimed."
