Prime Minister Scott Morrison had only one man in mind for the job of Australia's next governor-general.
That man, former NSW Governor David Hurley, will be sworn in at a ceremony in Canberra on Monday.
The former defence force chief assumes the post after the end of Sir Peter Cosgrove's five-year commission.
Mr Hurley became the NSW governor in 2014 after 42 years of service in the Australian Army, the last three of which he spent as chief of the defence force.
Mr Morrison will meet Mr Hurley and wife Linda outside Parliament House before the retired general receives the general salute.
In the Senate chamber, Australia's Chief Justice Susan Kiefel will swear in Mr Hurley, reading and signing the oaths of allegiance and office.
The prime minister and the governor-general will sign the proclamation to complete the ceremony.
In the Members' Hall, the national anthem and a welcome to the country ceremony will be followed by speeches from Mr Morrison, Opposition Leader Anthony Albanese and Mr Hurley.
Mr Hurley will receive a royal salute after being farewelled from parliament by Mr Morrison and wife Jenny, while the prime minister will be given a general salute.
Earlier in the year, Mr Hurley used an Australia Day speech to call for indigenous languages to be taught more widely in schools.
In December, he urged people to look beyond his military background after criticism that three of the last four appointments of governor-general have been retired army generals.

Mr Morrison gave some insight into his choice after appointing him late last year.
"General Hurley is known for looking people straight in the eye. Not up and not down. He was that way with those he led in the military and he's been that way as a governor and throughout his life," Mr Morrison said in December.
"Looking eye-to-eye, face-to-face, understanding people's challenges and issues one-on-one, in a very direct and very humble and a very humane way."
Facing questions about why he did not consider a woman to fill the role, Mr Morrison said Mr Hurley's selection was a "package deal" with his wife of more than 40 years.
The governor-general is appointed by the Queen in Commonwealth countries, on the advice of the prime minister, to be the representative of the Crown.
Mr Hurley was awarded the Distinguished Service Cross for his leadership during Operation SOLACE in Somalia in 1993.
He was also appointed a Companion of the Order of Australia in 2010 for eminent service to the army.
