Australia has signed and ratified many international conventions, declarations and treaties on human rights. The Australian Human Rights Commission oversees Australia’s responsibilities under some of these agreements. You can find the full list of treaties Australia has signed and are currently negotiating on the Australian Treaties Library (search by subject).
When a treaty is signed, it does not automatically become Australian law. The Australian Government negotiates and signs treaties but only the Australian Parliament can make laws. Sometimes, new laws aren’t required for Australia to meet its obligations under a treaty; existing laws will ensure Australia meets its treaty obligations. If new laws are required, bills will be introduced and passed by Parliament before the treaty will come into force.
More information on the treaty making process can be found at the Department of Foreign Affairs and Trade website.
