Allardyce first posting was Fiji, where, just two years after his arrival, he was named acting Resident Commissioner for the island of Rotuma. The following year as magistrate and seven years later he was appointed to the Native Regulation Board and made the commissioner of the Supreme Court. In 1894, he was made Commissioner for Native Lands and given a seat in the Legislative Council. In 1895, he was appointed Native Commissioner, the chief liaison between the Fijian natives and the British. The following year he was appointed Receiver-General. He subsequently became Colonial Secretary and a member of the Executive Council in 1898. In 1904, Allardyce was appointed as Governor of the Falkland Islands. After 10 years at the Falklands, he was then transferred to the Bahamas to become its governor, a position he held for six years. Allardyce then became governor of Tasmania but retired after only two years—taking the last three months as leave—as a result of his failure to obtain an increase in his salary of £2750. In fact, a statement made to the Parliament of Tasmania on his salary and allowances was followed by a vote by the Legislative Assembly to abolish his office, although the same motion was defeated in the Legislative Council. Nevertheless, when he left office he was widely praised for his performance of the office. Allardyce was subsequently ordered to Newfoundland where he was to succeed Sir Charles Alexander Harris as Governor of Newfoundland, where he was invited to become patron of the Great War Veterans Association. He was the official Crown representative of the unveiling of the National War Memorial by Field Marshal the Earl Haig on 1 July 1924. He officiated at the opening of the other national war memorial, Memorial University College, on 15 September 1925. Allardyce as governor was a key promoter in the decision awarding jurisdiction over most of the Labrador Peninsula to Newfoundland by the British Privy Council. In 1916, Allardyce was made a Knight Commander of the Order of St Michael St George by King George V. He was advanced to Knight Grand Cross of the Order of St Michael and St George in 1927. Allardyce married twice. First, in 1895, to Constance Angel Greene of Melbourne, Australia, daughter of Molesworth Richard Greene. She died in 1918; then, in 1920, he married Elsie Elizabeth Stewart, widow of A.C. Goodfellow. In 1923, Lady Allardyce helped start the Girl Guide movement in Newfoundland, and then in 1924, she established the Newfoundland Outport Nursing and Industrial Association. Allardyce was noted as one of the most competent administrators ever appointed by the Colonial Office to serve as the official representative of the British Crown in Newfoundland and Labrador. His brother Kenneth was also a colonial administrator, serving as Secretary for Native Affairs in Fiji.
