Australia, as a member of the Security Council for 1947, was
represented on the Commission of Investigation set up by that body in response to a complaint from Greece on 3 December 1946 about
violations of her northern frontiers. 

The Commission's report led, on 21 October 1947, to the establishment by the UN General Assembly of the Special Committee on the Balkans (UNSCOB) on which Australia was also represented. UNSCOB's functions were to observe the compliance of Greece, Albania, Bulgaria and Yugoslavia with the General Assembly's Resolution (109 (II)) calling for the restoration of normal conditions on their frontiers, the negotiated voluntary transfer of minority groups and the cessation of military and other assistance to armed groups aiming at the overthrow of lawful government.
 
Its terms of reference authorised UNSCOB to set up such 
sub-committees as it deemed necessary. Australian delegates participated in some of the sub-committees but took no active part in the Observation Groups set up to report on frontier situations. Their function was soon extended to include the investigation of incidents, a role which Australia considered not to be in accordance with the spirit of the 1947 Resolution. Although subsequent resolutions confirmed this role, Australia did not provide personnel for the Observation Groups, which represented the United Nation's first attempt at maintaining a peace-keeping force.
 
The first Australian delegate was B C Ballard, then attached to the Australian Embassy, Paris, who was in Salonika by 4 December 1947. He was joined on 19 December by A H Body who served as deputy/alternate delegate until recalled to Canberra in early March. Ballard was succeeded on 27 January 1948 by T G Glasheen, who was there
until October. From late April to late May 1948, Colonel W R Hodgson headed the delegation. Glasheen was replaced on 30 December 1948 by S L Atyeo who was joined on 28 February 1949 by Hugh Gilchrist (Ambassador to Greece 1968-1972) as deputy/alternate.
 
The only other staff of the delegation was a secretary (notably E F  Grimwade from December 1948-1952) who attended sessions and ran the delegation in the absence of accredited delegates. The Australian delegation moved from Salonika to Athens in mid-1948.
 
Throughout the existence of UNSCOB, Albania, Bulgaria and Yugoslavia declined to cooperate with it. On 23 January 1952, UNSCOB was abolished and replaced by a Balkan Sub-Commission of the Peace Observation Commission which carried on the Observation function until it was discontinued, at the request of Greece, on 1 August 1954.
