Robinson served as the governor of
South Australia, beginning in February 1883; the song "Unfurl the Flag", which he had composed, was played during his inauguration in
Adelaide. He had composed multiple songs previously in his life, including "Imperfectus", "I love thee so", "Remember me no more", "Severed", and "Thou art my Soul", Also in 1887, he turned down a request for his governorship of
Hong Kong, as he did not want to undergo its harsh climate. During 1889, from 9 March to November, while
Henry Brougham Loch was away, his return was praised enthusiastically by the citizens. According to the Australian Dictionary of National Biography, "he knew and understood more about Western Australia than any other imperial officer." Robinson chose
John Forrest to be the first Premier of Western Australia. Robinson had little to do involving politics as governor, due to the fact that Forrest was dominant over the cabinet and parliament, as well as because of constitutional conventions. His time as governor included the transition of the colony to self-governance in 1890. Robinson was offered the position of the colony's first agent general by Forrest 1891; however, he declined the offer. == Retirement and death ==
