Welcome to your third lesson. In our previous session, you learned to distinguish between the four key types of law-making power: specific, exclusive, concurrent, and residual. These are the essential building blocks for understanding Australia's federal system.
Today, we will assemble those blocks to explain how the Australian Constitution systematically divides law-making power between the Commonwealth and state parliaments. This is a central principle of Australian government and a frequent topic in SACs and exams. By the end of this lesson, you will be able to explain the complete mechanism for this division of power.
The Federal Compromise
To understand how the Constitution divides power, it's useful to first understand why. At Federation in 1901, the six self-governing colonies had to decide which powers they were willing to give up to form a new national government and which they wanted to keep. This agreement is often called the 'federal compromise' or 'federal bargain'.
The following video from Aussie Law provides excellent context on this arrangement. It explains that the Commonwealth was created by the states to handle national issues, while the states intended to remain autonomous bodies responsible for their own affairs.
Australian FEDERALISM EXPLAINED (Structure, Institutions and Powers of States and Cth) | AUSSIE LAW
Watch the video "Australian FEDERALISM EXPLAINED" to understand the foundational agreement between the states and the new Commonwealth.
Please watch two segments. First, the section on the Federal Entity, which explains the creation of the Commonwealth. Then, skip ahead to the section explaining the states' role, focusing on the idea that they surrendered only necessary powers.
As the video highlights, the states agreed to surrender "only so much of their powers as is necessary" to the new Commonwealth government. This principle is directly reflected in the structure of the Constitution.
The Constitutional Blueprint for Dividing Power
The Constitution achieves this division through a clear and deliberate blueprint:
- It grants a specific list of powers to the Commonwealth Parliament. These are the specific powers we covered previously, found mainly in sections 51 and 52. These powers were considered necessary for the "peace, order, and good government" of the new nation, covering areas like defence, immigration, and currency.
- It allows the state parliaments to retain all their original law-making powers, except for those made exclusive to the Commonwealth. These retained powers are the residual powers. The Constitution doesn't list them because they are simply everything that was 'left over' after the specific powers were handed to the Commonwealth. Sections 106 and 107 of the Constitution confirm the continuation of state constitutions and powers.
This creates a fundamental split: the Commonwealth has limited, enumerated powers, while the states have broad, non-specific powers.
The following resource from the Parliamentary Education Office (PEO) clearly explains this structure.

This reading details the constitutional basis for the powers of the Commonwealth and state parliaments.
Please read two short sections. First, read the paragraphs under the heading Commonwealth Legislative Powers. This summarises the basis for federal power. Second, read the paragraphs under The States and their Legislative Powers. This explains the source and scope of state power.
To summarise the relationship between the power types:

Managing the Overlap: The Tie-Breaker Rule
As the diagram shows, the area of concurrent powers is shared. Both the Commonwealth and the states can make laws on these subjects. This naturally leads to a crucial question: what happens if their laws conflict?
The drafters of the Constitution foresaw this and included a mechanism to resolve it: Section 109.
Section 109 of the Australian Constitution states:
When a law of a State is inconsistent with a law of the Commonwealth, the latter shall prevail, and the former shall, to the extent of the inconsistency, be invalid.
This section acts as a constitutional tie-breaker. If a valid Commonwealth law and a state law clash in a concurrent area, the Commonwealth law overrides the state law. The state law is not struck out permanently; it just becomes inoperative as long as the conflicting Commonwealth law exists. This rule is a key reason why the Commonwealth is often seen as the more powerful partner in the federation.
The Division of Powers in Practice
The division of powers has a direct impact on the services and laws that affect daily life. The table in the following resource provides excellent, concrete examples of the responsibilities of each level of government.
This resource includes a practical table showing the typical responsibilities of Federal, State, and Local governments.
Scroll down to the table under the heading What Does Each Level of Government Do?. As you review it, connect the responsibilities back to the types of powers. For example, 'Defence' is an exclusive Commonwealth power, while 'Schools' and 'Hospitals' fall under the states' residual powers.
A Dynamic Balance
While the Constitution sets out the rules, the actual balance of power between the Commonwealth and the states is not static. Two key factors have allowed the Commonwealth to extend its influence, even into areas of residual state power:
-
Financial Dominance (Section 96): The Commonwealth raises the vast majority of taxes in Australia (especially income tax). Section 96 of the Constitution allows it to grant money to states and, crucially, to attach conditions to those grants. For example, the Commonwealth has no specific power over education, but by providing funding for universities on the condition they meet certain requirements, it can effectively influence policy in that area.
-
High Court Interpretation: The High Court of Australia interprets the Constitution. Over time, its interpretations of the Commonwealth's specific powers (like the 'external affairs' power) have often been broad, allowing federal laws to cover subjects not explicitly listed in section 51.
The PEO resource you read earlier also has an excellent summary of these factors. It is worthwhile to review this, as it provides depth for an evaluative SAC response.

This final reading summarises how Section 109 and financial power have shaped the relationship between the Commonwealth and states.
Return to the "Overview" page from the PEO. Under the heading The Relationship between Commonwealth and State Powers, read the paragraphs that explain the impact of Section 109 and Section 96 grants.
Key Takeaways
- The Constitution divides power by granting a list of specific powers to the Commonwealth and leaving all remaining residual powers with the states.
- Specific powers can be exclusive (Commonwealth only) or concurrent (shared with states).
- Section 109 is the constitutional tie-breaker: where valid Commonwealth and state laws conflict in a concurrent area, the Commonwealth law prevails.
- The balance of power is not fixed; it shifts due to factors like the Commonwealth's financial dominance (s96 grants) and High Court interpretation.
This lesson has provided the complete model for how law-making power is divided. In our next lesson, we will focus specifically on Section 109 and work through a practical example of how to apply it to resolve a conflict between laws—a classic SAC scenario.
