Sir Robert was appointed Governor of South Australia in August 1952. He and Lady George arrived in Adelaide early the following year. The Premier, Sir Thomas Playford, noted in his welcome address to Sir Robert that governors were expected to be "an inspiration in times of danger." Playford's words turned out to be portentous – South Australia would suffer through earthquake, fire and flood in consecutive years during Sir Robert's tenure. In March 1954, the worst earthquake in Adelaide's history damaged Government House, along with many other buildings in the city. Less than a year later, the Governor's summer residence at Marble Hill was destroyed in the Black Sunday bushfires of January 1955. He and his wife and staff sheltered under wet blankets in the driveway, and were lucky to escape with their lives. In a particularly cruel twist of fate, all Sir Robert and Lady George's possessions were lost in the fire, having been relocated to Marble Hill while Government House was undergoing repairs for the damage suffered in the earthquake. Finally, the 1956 Murray River flood was the largest in recorded history. On 20 August, Sir Robert surveyed the flood-hit areas in a light aircraft, and said he was "appalled at the tremendous area underwater and the terrific damage which had resulted." Sir Robert was a colourful governor, once demanding a personal helicopter from Premier Playford. Although admired for his bravery, Sir Robert was considered old-fashioned by the masses, particularly due to his impatience, polo-playing, and his habit of carrying a fly-whisk and a cane. Lady George was an ardent supporter of many charities, but her support for traditional family roles was not popular with the emerging feminists; once, while officiating at the opening of new laboratories at a girls' college, she claimed: "The most important thing for a girl is to learn how to run a home well." Despite their frequent clashes, Playford supported George and the dignity of the Vice-Regal post in a 1956 court case regarding the cook's wages. The prosecuting lawyer was future Labor premier Don Dunstan. Playford negotiated an out-of-court settlement on condition that Dunstan and his Labor colleagues in the House would not debate the budget item. Labor maverick Samuel Lawn did not honour the agreement, and tried to raise a public scandal. Playford responded by extending George's term.

Retirement and accidental death
George and his family retired to England in 1959 after which he held no further government appointments. He died in a London Hospital on 13 September 1967, after being accidentally hit by a car and not regaining consciousness.
