Serving until 1956, Walker's next posting was to New York as Australia’s Permanent Representative to the United Nations. On 12 January 1956 he presented his credentials to UN Secretary-General Dag Hammarskjöld. During his time at the UN, Australia held a non-permanent seat on the United Nations Security Council (1956–1957) and during Australia's term the council dealt with such matters as the Suez Crisis and the Soviet invasion of Hungary. Walker himself served as President of the Council twice, in June 1956 and June 1957. Walker also served as Australia's representative on the United Nations Trusteeship Council (1956–1958).

With the end of the war, Walker's government position was abolished, and was sent by the Commonwealth to be chief of the country programs branch of the United Nations Relief and Rehabilitation Administration in Washington, DC. With the abolition of that body however in 1947, Walker joined the Department of External Affairs and was sent to be a counsellor at the Australian legation in Paris, with special responsibility for economic matters at the Paris Peace Conference. While in Paris, Walker was involved in the establishment of the United Nations Educational, Scientific and Cultural Organization (UNESCO), serving as Chairman on the first executive board (1948–1950) and was elected to serve as chairman of the UNESCO finance committee in 1949–1950. In 1948 he was also appointed as Australia's representative on the United Nations Economic and Social Council until 1950. He remained in Paris until 1950, when he returned to Australia to take up an appointment as an Executive member of the National Security Resources Board, which had been established following the outbreak of the Korean War.

He served the NSW Treasury in this capacity until in March 1939, he was appointed to succeed Frank Mauldon as Professor of Economics at the University of Tasmania and also as an economic adviser to the Tasmanian Government. With the outbreak of war, Walker studied many aspects of Australia's economy under wartime conditions and regulation. In December 1941 he was appointed chief economic adviser and later deputy director-general of the newly established Department of War Organization of Industry in Melbourne. Walker was also appointed a member of the Commonwealth Advisory Committee on Finance and Economic Policy. In office as Professor of Economics until 1946, in 1949 Walker was awarded the degree of Doctor of Letters (Litt.D) by Cambridge University in recognition of his prolific publications on the Australian war economy.

After graduating with first class honours from his master's degree, Walker worked with Robert Madgwick to publish an economics textbook "An Outline of Australian Economics" (published 1932). On account of his academic success, Walker was also awarded a Rockefeller Foundation scholarship in 1931 and entered St John’s College, Cambridge, studying for a doctorate in economics. While at Cambridge Walker joined the Political Economy Club, which included amongst its founders John Maynard Keynes, and he became a firm adherent to Keynes' ideas on economics throughout his life. His doctoral dissertation, entitled "Australia in the World Depression", was supervised by Dennis Robertson and Arthur Cecil Pigou and at award in 1933 was the second PhD in economics at Cambridge. On 8 April 1933, at Beaumont, Belgium, Walker married Louise Clementine Donckers, a schoolteacher.

On his return to Australia, Walker resumed his position as a lecturer in economics at the University of Sydney from 1933. Walker later made an appearance before the 1936-37 Royal Commission on Monetary and Banking Systems, which was established by the Federal Government of Joseph Lyons to examine potential changes to the banking sector. At the royal commission, Walker argued that monetary policy should have two objectives: "the avoidance or mitigation of depressions" and "the stabilization of the purchasing power of money". Impressed by his submissions, the Commonwealth Government sent Walker to Geneva as a delegate to the League of Nations in 1937 and on his return to Australia in 1938 he was appointed an economic adviser to the New South Wales Treasury.
