Australia

07-06-1971

In considering the 'Statement by the Government of the Commonwealth of Australia Concerning Acceptance by the Government of the Commonwealth of Australia of the Obligations of Membership in the Organisation' it is felt that the Council would find it useful to have before it the following information about certain matters relating to such membership.
The Government of Australia wishes to inform the Council of the fact that 'the Commonwealth of Australia' comprises the six component States of the Australian Federation, together with mainland federal territories, the Australian Capital Territory and the Northern Territory. The Government is also responsible for the international relations of the Territory of Papua and New Guinea and of certain other small island territories, which are collectively known as the External Territories, and which do not form part of the Commonwealth of Australia. It is the understanding of the Government of Australia that the obligations of Members of the Organisation are not applicable in their overseas territories, except where, and to the extent that, it is so stated.
The Government of Australia also wishes to inform the Council that the States of Australia, and not the Commonwealth of Australia itself, may have constitutional authority to act with respect to some of the matters which are within the scope of the obligations resting on Members of the Organisation. The Commonwealth of Australia undertakes, however, to discharge the obligations of a Member of the Organisation to the fullest extent compatible with the constitutional system of Australia.

New Zealand

29-05-1973

The Government of New Zealand declares that its accession to the Convention shall not extend to the island territories for whose international relations it is responsible.
