The Chief of the Australian Defence Force, David Hurley, was named the new NSW Governor on Thursday.
The Wollongong-born defence chief will replace current Governor Marie Bashir in the position, taking the oldest public office in Australia.
The Premier, Mike Baird, made the announcement at 11.30am.
General Hurley, 61, graduated from the Royal Military College at Duntroon in 1975 and was swiftly promoted through the force's ranks, becoming Chief of the Defence Force in 2011.
In 2010 he became a Companion of the Order of Australia for eminent service to the defence force. He has also been also awarded the Distinguished Service Cross for service in Somalia.
General Hurley will step down from the defence force in July.
