, 26 March 1925. , 17 March 1925. De Chair had been interested in serving in a viceregal role as early as 1922, when he put his name forward to the
Colonial Office for the position of
Governor of South Australia. This position however, went to
Sir Tom Bridges instead and the First Lord of the Admiralty,
Leo Amery, put de Chair's name forward for the
Governor of New South Wales. This position, which had been vacant since the death of
Sir Walter Davidson in September 1923, was the same one his uncle,
Sir Harry Rawson, had held twenty years earlier, and to which he was appointed on 8 November 1923. Arriving in Sydney on 28 February 1924, de Chair became governor in relatively calm political times and was warmly received in the city with great fanfare. On de Chair's appointment, the President of the
Royal Australian Historical Society, Aubrey Halloran, compared Admiral de Chair to the first Governor, Captain
Arthur Phillip: "Our new Governor's reputation as an intrepid sailor and ruler of men evokes from us a hearty welcome and inspires us to place in him the same confidence that [Arthur] Phillip received from his gallant band of fellow-sailors and the English statesmen who sent him." The political makeup of the State changed shortly after his arrival. The conservative
Nationalist/
Progressive coalition government of
Sir George Fuller, with whom de Chair was sympathetic, was defeated at the
May 1925 state election by the
Labor Party under
Jack Lang. De Chair recorded that their position comprised "radical and far-reaching legislation, which had not been foreshadowed in their election speeches". He also later wrote that Lang's "lack of scruple gave me a great and unpleasant surprise". With the
Labor government only holding a single seat majority in the
Legislative Assembly and only a handful of members in the upper
Legislative Council, one of Lang's main targets was electoral reform. The Legislative Council, comprising members appointed by the Governor for
life terms, had long been seen by Lang and the Labor Party as an outdated bastion of conservative privilege holding back their reform agenda. Although previous Labor premiers had managed to work with the status quo, such as requesting appointments from the Governor sufficient to pass certain bills, Lang's more radical political agenda required more drastic action to ensure its passage. Consequently, Lang and his government sought to abolish the council, along the same lines that their Queensland Labor colleagues had done in 1922 to their
Legislative Council, by requesting from de Chair enough appointments to establish a Labor majority in the council that would then vote for abolition. While Lang's attempts ultimately failed, de Chair failed to gain the support of an indifferent
Dominions Office. With Lang's departure in 1927, the
Nationalist government of
Thomas Bavin invited him in 1929 to stay on as Governor for a further term. De Chair agreed only to a year's extension and retired on 8 April 1930. ==Later life==
