A treaty is an international agreement concluded in written form between two or more States (or international organisations) and is governed by international law. A treaty gives rise to international legal rights and obligations.

The power to enter into treaties is an Executive power within section 61 of the Australian Constitution. Given that any treaty necessarily involves an element of Australia's foreign relations, the Minister for Foreign Affairs and the Department of Foreign Affairs and Trade (DFAT) have responsibility for treaties. DFAT’s International Law: Advising and Treaties Section (Treaties Section) is responsible for, and should be consulted on, all aspects of the treaty-making process.

Australia’s treaty-making process

General guidance on the steps in Australia’s treaty-making process is available in this Guidance note on Australia’s treaty-making process.

These steps include:

  • seeking a mandate to negotiate from the Minister for Foreign Affairs
  • negotiating and finalising the text of the treaty;
  • seeking the approval of relevant Ministers and the Executive Council for Australia to enter into the treaty;
  • arranging for signature of the treaty;
  • tabling the treaty in Parliament for scrutiny by the Joint Standing Committee on Treaties (JSCOT); and
  • any other steps, such as passage of any implementing legislation, required to enable entry into force of the treaty.
  • Any Commonwealth Government agencies considering a treaty action should consult DFAT’s Treaty Section at an early stage. This includes negotiating or entering into a new treaty, as well as amending, terminating or withdrawing from an existing treaty.

Instruments of less-than-treaty status

Treaties must be distinguished from instruments of less-than-treaty status, often referred to as memoranda of understanding. These instruments embody political commitments by the participants, but are not legally binding. As they are not binding under international law, instruments of less-than-treaty status are not subject to Australia’s treaty-making process.

To avoid any misunderstandings over the status of an instrument, it is important that the intention of the participants is clear and that this is reflected in the language used to draft the instrument.

General guidance on Australia’s practice for concluding less-than-treaty status instruments can be found in this Guidance note on Australia’s practice with respect to less-than-treaty status instruments.
