With reference to my memorandum of 27th March, 1947, and your reply of 8th May, 1947, the question of the annexation by Australia of Heard Island has been carefully considered in the light of the views you have expressed and of those of other Departments concerned.
2. While it is appreciated that the value of Heard Island from a strategical point of view would not warrant its annexation, other considerations have influenced a decision to take the necessary steps to send a mission there as part of Antarctic Exploration plans. The Executive Planning Committee for the Australian Antarctic Expedition considers that from a scientific point of view, it is important for Australia to have available a possible site for the establishment of a meteorological station in this region.  In addition, it is felt that, while Heard Island does not at present appear capable of use as a staging point for air navigation, technical developments in the future may make its employment practicable. 
3. At a recent meeting  in Canberra, the Executive Planning Committee has therefore decided, as part of the programme of scientific work to be carried out during the Summer, to send small scientific parties to Macquarie and Heard Islands to cover as wide a range of meteorological observation as possible. Winter parties, consisting of about six men, are to be left at each island base.
Hitherto, a proper survey of Heard Island has been lacking and it will now be possible to undertake this work. At the time of landing at Heard Island, a formal act of annexation may be executed.
