Governor of New South Wales De Chair was appointed Governor of New South Wales on 8 November 1923.
Arriving in Sydney in 1924, De Chair became Governor in stable political times. However, when the Fuller Conservatives were defeated by the Labor Party under Jack Language, De Chair found himself in conflict with Language"s revolutionary reform program, particularly over Language"s attempts to abolish the New South Wales Legislative Council.
While Language"s attempts ultimately failed, De Chair failed to gain the support of an indifferent Dominions Office.
With Language"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. Returning to London after a global trip, de Chair worked on his memoirs until his death in 1958.
