state constitutions in Australia

{{no sources section|date=October 2024}}

Australia operates as a federal parliamentary democratic constitutional monarchy, with the monarch, currently King Charles III, as the head of state. The state governments function within the framework of a federal system, where powers are divided between the federal government and state governments. While there are some similarities among the state constitutions, each state has its unique provisions and structures. Generally, state constitutions establish a system of responsible government, where the executive is accountable to the legislative branch.

In Australia, State constitutions do not meaningfully limit the power of State parliaments. Each of Australia's State parliaments is understood to have been vested with plenary power; additionally, their constitutions can be altered by simple acts of the State legislature. In this respect, they may be understood as sovereign legislatures exclusively at the State level. They are not truly sovereign legislatures however, as laws passed by Australia's state parliaments are subject to the federal constitution. (see for example Section 92 and 109)

This situation may be contrasted with the constitutional arrangements of other state-level governments in other federalist jurisdictions; like that of Texas, a jurisdiction where the constitutional arrangements only provide the legislature with powers explicitly granted to it within the state's constitutional document.

The process for amending state constitutions in Australia varies by state. Generally, amendments require a majority vote in both houses of parliament, and sometimes approval through a state-wide referendum. However, some states have different amendment procedures, and not all changes require a referendum. However, in theory, procedural restrictions can be removed by the State parliaments through simple legislative acts. They therefore do not bind State parliaments to the same degree that the Commonwealth constitution binds the Australian Government.

Constitutional reform and amendments at the State level have been a source of discussion for legal scholars, politicians, and the general public. Issues discussed in debates about reform have included the role of the monarchy, rights and recognition for Indigenous Australians, and human rights.
