Australia Act 1986 in the context of "Commonwealth Parliament"

The governor of New South Wales is the representative of the monarch, King Charles III, in the state of New South Wales. In an analogous way to the Governor-General of Australia at the national level, the Governors of the Australian States perform constitutional and ceremonial functions at the state level. The governor is appointed by the monarch on the advice of the Premier of New South Wales, and serves in office for an unfixed period of time—known as serving At His Majesty's pleasure—though five years is the general standard of office term. The current governor is retired judge Margaret Beazley, who succeeded David Hurley on 2 May 2019.

The office has its origin in the 18th-century colonial governors of New South Wales upon its settlement in 1788, and is the oldest continuous institution in Australia. The present incarnation of the position emerged with the Federation of Australia and the New South Wales Constitution Act 1902, which defined the viceregal office as the governor acting by and with the advice of the Executive Council of New South Wales. However, the post still ultimately represented the Government of the United Kingdom until, after continually decreasing involvement by the British government, the passage in 1942 of the Statute of Westminster Adoption Act 1942 (see Statute of Westminster) and the Australia Act 1986, after which the governor became the direct, personal representative of the sovereign.

The monarchy of Australia is a central component of Australia's system of government, by which a hereditary monarch serves as the country's sovereign and head of state. It is a constitutional monarchy, modelled on the Westminster system of parliamentary democracy and responsible government, while incorporating features unique to the Constitution of Australia.

The present monarch is King Charles III, who has reigned since 8 September 2022. The monarch is represented at the federal level by the governor-general (currently Samantha Mostyn), in accordance with the Australian Constitution and letters patent from his mother and predecessor, Queen Elizabeth II. Similarly, in each of the Australian states the monarch is represented by a governor (assisted by a lieutenant-governor; generally the chief justice of the state's supreme court), according to the Australia Act and respective letters patent and state constitutions. In the Northern Territory (which is legally subordinate to the federal government), the monarch is represented by an administrator appointed by the governor-general. The monarch appoints the governor-general on the advice of the prime minister, and appoints the state governors on the advice of the respective premiers. These are the only mandatory constitutional functions of the monarch of Australia.
