Australian labour law sets the rights of working people, the role of trade unions, and democracy at work, and the duties of employers, across the Commonwealth and in states. Under the Fair Work Act 2009, the Fair Work Commission creates a national minimum wage and oversees National Employment Standards for fair hours, holidays, parental leave and job security. The FWC also creates modern awards that apply to most sectors of work, numbering 150 in 2024, with minimum pay scales, and better rights for overtime, holidays, paid leave, and superannuation for a pension in retirement. Beyond this floor of rights, trade unions and employers often create enterprise bargaining agreements for better wages and conditions in their workplaces. In 2024, collective agreements covered 15% of employees, while 22% of employees were classified as "casual", meaning that they lose many protections other workers have. Australia's laws on the right to take collective action are among the most restrictive in the developed world, and Australia does not have a general law protecting workers' rights to vote and elect worker directors on corporation boards as do most other wealthy OECD countries.
Australian constitutional law is the area of the law of Australia relating to the interpretation and application of the Constitution of Australia. Legal cases regarding Australian constitutional law are often handled by the High Court of Australia, the highest court in the Australian judicial system. Several major doctrines of Australian constitutional law have developed.
Amalgamated Society of Engineers v Adelaide Steamship Co Ltd, commonly known as the Engineers case, was a landmark decision by the High Court of Australia on 31 August 1920. The immediate issue concerned the Commonwealth's power under s 51(xxxv) of the Constitution but the court did not confine itself to that question, using the opportunity to roam broadly over constitutional interpretation.
Melbourne Corporation v Commonwealth, also known as the Melbourne Corporation case or the State banking case, is an important case in Australian constitutional law. It stands for the proposition that there are limits on the scope of express Commonwealth legislative powers which can be implied from the federal character of the Constitution.
The separation of powers in Australia is the division of the institutions of the Australian government into legislative, executive and judicial branches. This concept is where legislature makes the laws, the executive put the laws into operation, and the judiciary interprets the laws; all independently of each other. The term, and its occurrence in Australia, is due to the text and structure of the Australian Constitution, which derives its influences from democratic concepts embedded in the Westminster system, the doctrine of "responsible government" and the United States version of the separation of powers. However, due to the conventions of the Westminster system, a strict separation of powers is not always evident in the Australian political system, with little separation between the executive and the legislature, with the executive required to be drawn from, and maintain the confidence of, the legislature; a fusion.
Section 51(xx) of the Australian Constitution is a subsection of Section 51 of the Australian Constitution that gives the Commonwealth Parliament the power to legislate with respect to "foreign corporations, and trading or financial corporations formed within the limits of the Commonwealth". This power has become known as "the corporations power", the extent of which has been the subject of numerous judicial cases.
In Australian constitutional law, chapter III courts are courts of law which are a part of the Australian federal judiciary and thus are able to discharge Commonwealth judicial power. They are so named because the prescribed features of these courts are contained in chapter III of the Australian Constitution.
R v Barger is a 1908 High Court of Australia case where the majority held that the taxation power could not be used by the Australian Parliament to indirectly regulate the working conditions of workers. In this case, an excise tariff was imposed on manufacturers, with an exemption being available for those who paid "fair and reasonable" wages to their employees.
Coleman v Power was a High Court of Australia case that dealt with the implied freedom of political communication found in the Australian Constitution.
Victoria v Commonwealth (1971) 122 CLR 353, commonly referred to as the Payroll Tax Case, was a case decided in the High Court of Australia regarding the scope of the Commonwealth's taxation power and the extent to which it can burden a state's structural integrity.
Re Australian Education Union & Australian Nursing Federation; ex parte Victoria is a High Court of Australia constitutional law case that involves the scope of the intergovernmental immunity doctrine in Australian constitutional law.
The persona designata doctrine is a doctrine in law, particularly in Canadian and Australian constitutional law which states that, although it is generally impermissible for a federal judge to exercise non-judicial power, it is permissible for a judge to do so if the power has been conferred on the judge personally, as opposed to powers having been conferred on the court. The doctrine in the more general sense has been recognised throughout the common law countries. Persona designata, according to Black's Law Dictionary, means "A person considered as an individual rather than as a member of a class"; thus it may be a person specifically named or identified in a lawsuit, as opposed to the one belonging to an identified category or group. While it has its origin in Montesquieu's doctrine of the separation of powers, it can be traced back as far as Aristotle's Politics.
Australian corporations law has historically borrowed heavily from UK company law. Its legal structure now consists of a single, national statute, the Corporations Act 2001. The statute is administered by a single national regulatory authority, the Australian Securities & Investments Commission (ASIC).
New South Wales v Commonwealth, commonly known as the Wheat case, or more recently as the Inter-State Commission case, is a landmark Australian judgment of the High Court made in 1915 regarding judicial separation of power. It was also a leading case on the freedom of interstate trade and commerce that is guaranteed by section 92 of the Constitution.
Section 92 of the Constitution of Australia, as far as is still relevant today is:
... trade, commerce, and intercourse among the States, whether by means of internal carriage or ocean navigation, shall be absolutely free.
In Australia, the doctrine of intergovernmental immunity defines the circumstances in which Commonwealth laws can bind the States, and where State laws can bind the Commonwealth. This is distinct from the doctrine of crown immunity, as well as the rule expressed in Section 109 of the Australian Constitution which governs conflicts between Commonwealth and State laws.
Section 99 of the Constitution of Australia, is one of several important non-discrimination provisions that govern actions of the Commonwealth and the various States.
Section 90 of the Constitution of Australia prohibits the States from imposing customs duties and excise duties. The section bars the States from imposing any tax that would be considered to be of a customs or excise nature. While customs duties are easy to determine, the status of excise, as summarised in Ha v New South Wales, is that it consists of "taxes on the production, manufacture, sale or distribution of goods, whether of foreign or domestic origin." This effectively means that States are unable to impose sales taxes.
Deakin v Webb was one of a series of cases concerning whether the States could tax the income of a Commonwealth officer. The High Court of Australia overruled a decision of the Supreme Court of Victoria, holding that the States could not tax the income of a Commonwealth officer. This resulted in conflict with the Privy Council that was ultimately resolved by the passage of Commonwealth law in 1907 to permit the States to tax the income of a Commonwealth officer. The constitutional foundation of the decision was overturned by the subsequent decision of the High Court in the 1920 Engineers' Case.
Judicial independence is regarded as one of the foundation values of the Australian legal system, such that the High Court held in 2004 that a court capable of exercising federal judicial power must be, and must appear to be, an independent and impartial tribunal. Former Chief Justice Gerard Brennan described judicial independence as existing "to serve and protect not the governors but the governed", albeit one that "rests on the calibre and the character of the judges themselves". Despite general agreement as to its importance and common acceptance of some elements, there is no agreement as to each of the elements of judicial independence.
