The Australia’s Foreign Relations Act and Australia’s Relationship with International Law

This article examines the consequences of the Australia’s Foreign Relations (State and Territory Arrangements) Act 2020 (Cth) (‘Foreign Relations Act’) for international law. It argues that the arrangements entered into by state, territory and local governments to which the Foreign Relations Act applies can be relevant to international law in three ways. First, they may relate indirectly to Australia’s international legal obligations. Second, they may be a means by which Australian subnational governments claim a role for themselves in governance on global issues. Third, as an exercise of diplomacy, they influence the relations Australia maintains with other nations and the way in which it participates in the international system. As the states and territories in particular become more assertive, including on international issues such as climate change, giving the Commonwealth complete control over such arrangements may impact Australia’s relationship with international law.
