Treaties are agreements entered into between States, either bilaterally or multilaterally. The Commonwealth, and not the States, is Australia’s international representative. It is within executive power to negotiate and execute such treaties but international treaties are not self-executing, requiring incorporation by legislation into domestic law (Encyclopaedic Australian Legal Dictionary).
Most treaties do not come into force when signed. They have a clause which specifies the requirements of the treaty entering into force. The clause may include a ratification date and a requirement that a certain number of parties have ratified before it can become law.
The Australian Treaty Database (DFAT) and the Australian Treaties Library (AustLII), which contains the Australian Treaty Series, are good resources when looking for Australian treaties. These resources contains all multilateral and bilateral treaties to which Australia is a signatory.
Hein Online Treaties and Agreements Library has United States treaties and the WorldLII International Treaties Collection is a good starting point to locate a range of treaties from other jurisdictions such as the United Kingdom, Canada and New Zealand.
