Rear Admiral Sir David James Martin, was a senior officer of the Royal Australian Navy and later Governor of New South Wales. He also established the Sir David Martin Foundation to assist young Australians in crisis.

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.
