On 30 August 1933 the Minister for Commerce, Frederick Stewart, secured Cabinet approval for the establishment of several Trade Commissions in the East, with Batavia in the Netherlands East Indies being one of the most likely locations.
However a decision to appoint a commissioner was delayed pending the report of Attorney General and Minister for External Affairs John Latham's fact-finding mission to the Far East, which found a dire need for Australian trade representative to improve mercantile connections in the region.
Following Latham's return the Australian Government agreed to appoint a new Trade Commissioner, and the appointment of Charles Edward Critchley to Batavia, alongside appointments to Tokyo and Shanghai, was announced on 7 June 1935 by acting Prime Minister Earl Page.
Arriving in September, Critchley met with Governor-General Bonifacius Cornelis de Jonge and set up offices in the Chartered Bank Building in Tambora, Old Batavia.
In January 1938, Critchley was succeeded by Herbert Anton Peterson, who was given the new title of "Australian Government Commissioner", which was changed to remove confusion that the "Trade Commissioner" was merely a commercial representative.
Commissioner Peterson served until escaping to Australia a few days after the Japanese invasion of Java in 1942.

Early Australian arrangements to establish diplomatic relations with Indonesia after the Indonesian proclamation of Independence on 17 August 1945 were complicated by the British and Dutch involvement in military activities in Indonesia in the next few years.
Australia was dissuaded from establishing a consulate-general in Batavia in 1945 and instead sent a political representative to be attached to the Allied Forces, Netherlands East Indies (AFNEI), the command controlling areas of the Dutch East Indies liberated from Japanese forces.
William Macmahon Ball, the Australian Political Representative to the AFNEI, arrived in Batavia on 7 November 1945 and returned to Australia in December 1945.
In March 1946 the Department of External Affairs appointed Alfred Deakin Brookes as the new Political Representative.
However, his departure in early June, owing to ill health, coincided with the arrival of Justice Richard Kirby, who acted as Political Representative in his absence before returning to Australia on 28 July 1946.
Bertram Ballard was appointed as Australian Political Representative with AFNEI on 16 August 1946, as political representative Ballard was advised by Minister for External Affairs, Herbert Evatt directed him to establish informal relations with the Indonesians and to act as Australia's de facto representative to the republican government in Jogjakarta.

The post of Consul-General was created following the departure of AFNEI in late 1946 following the Indonesia-Dutch settlement, and Ballard was formally appointed Consul-General on 5 December 1946 and accredited by the Netherlands East Indies Government on 12 February 1947.
He held this appointment until September 1947 when Charles Eaton, the former Consul to Portuguese Timor, replaced him.
In April 1950, the Consulate-General in Jakarta was raised to the status of an embassy, with the first Australian Ambassador to Indonesia, John Hood, appointed by External Affairs Minister Percy Spender.
