Origins of Australian law (SACE Stage 2 Legal Studies)
“Explain the origins of the Australian legal system, including the reception of English law and the place of Aboriginal and Torres Strait Islander customary law.”
The Australian legal system grew out of English law, which was received when British colonies were established. Australia inherited the common law tradition, the doctrine of precedent and the Westminster parliamentary system. For most of its history the law ignored the legal systems of Aboriginal and Torres Strait Islander peoples, treating the land as terra nullius, until the High Court in Mabo rejected that idea and recognised native title.

What this dot point is asking
You must explain how Australian law originated in English law, what was inherited, and how the law has dealt with Aboriginal and Torres Strait Islander legal traditions.
Reception of English law
When Britain established colonies in Australia from 1788, it brought English law with it. This is called the reception of English law. The colonies were treated as settled rather than conquered, which meant English law applied automatically as the law of the colony.
Reception is the process by which a colony takes on the law of the colonising country. In Australia, English common law and relevant English statutes were received as the foundation of the colonial legal system.
Australia inherited several enduring features from this English foundation.
- The common law tradition, where judges develop law through decided cases.
- The doctrine of precedent, under which courts follow earlier decisions of higher courts.
- The Westminster system of responsible parliamentary government.
- The adversarial system of trial.
- Core legal concepts such as the presumption of innocence and trial by jury.
Growing independence
Over time Australian law became independent of England. Federation in 1901 created a national parliament and the High Court. Appeals to the Privy Council in London were gradually abolished, and the Australia Acts 1986 ended the remaining legal links, confirming that Australian courts and parliaments are the final source of Australian law.
The Australia Acts 1986, passed by both the Australian and United Kingdom parliaments, severed the last legal ties to Britain. After 1986 no British law could apply to Australia and no Australian case could be appealed to London, making Australian law fully autonomous.
Aboriginal and Torres Strait Islander law
Aboriginal and Torres Strait Islander peoples had complex systems of law and custom long before 1788, governing land, kinship and obligations. For most of Australian legal history these systems were not recognised. The land was treated as terra nullius, meaning land belonging to no one, which was used to justify the assertion that English law applied to empty territory.
Terra nullius means land belonging to no one. It was the legal fiction used to treat Australia as unowned at settlement, which denied the existence of pre-existing Aboriginal and Torres Strait Islander systems of law and land ownership.
This changed with the High Court decision in Mabo v Queensland (No 2) (1992), which rejected terra nullius and recognised that native title could survive where a connection to land had been maintained. The Native Title Act 1993 (Cth) then created a national framework for claiming and recognising native title.
Do not say Mabo gave Aboriginal people ownership of all land or overturned all property rights. Mabo recognised that native title can exist where a continuing connection to land is shown and where it has not been extinguished by valid government grants. It corrected a legal fiction rather than redistributing land generally.
Why origins matter
Understanding origins explains why the Australian system looks the way it does. The common law and precedent come from England, which is why courts make law as well as parliament. The recognition of native title shows that the law can correct its own historical wrongs through the courts, an example of the legal system responding to changing community values. It also shows the tension between certainty, the inherited tradition, and the need for the law to reflect justice for all groups.
If a question asks about the dynamic nature of the legal system or how the law responds to social change, the move from terra nullius to native title is a powerful example. Pair the inherited English foundation with the Mabo correction to show both tradition and change in one answer.
Connection to the rest of the course
These origins underpin sources of law, the doctrine of precedent and the constitutional structure created at Federation. The recognition of native title connects directly to rights protection, law reform and the role of the High Court in shaping the rights of groups within the Australian community.
A SACE extended response rewards a structured, evaluative argument grounded in authority.
Step 1: State a contention
Argue that recognition has been limited and late, with most change coming through the courts rather than parliament.
Step 2: Establish the period of non-recognition
Explain the reception of English law, the fiction of terra nullius and the treatment of the colonies as settled.
Step 3: Establish the change
Explain Mabo (1992) rejecting terra nullius and the Native Title Act 1993 (Cth) creating a national framework.
Step 4: Evaluate the extent
Weigh the limited and conditional scope of native title against the significance of correcting a legal fiction.
Step 5: Reach a judgement
Conclude that recognition is real but partial, balancing inherited tradition against the law's capacity to reform.

SACE 2021-style4 marksExplain the doctrine of terra nullius and how it affected the recognition of Aboriginal and Torres Strait Islander law.Show worked answer →
A short-answer question worth 4 marks wants a clear definition and a linked consequence, not a long narrative.
Definition. Terra nullius means land belonging to no one; it treated Australia as unowned at settlement.
Effect. It denied the existence of pre-existing Aboriginal and Torres Strait Islander systems of law and land ownership, so English law was applied as if to empty territory and customary law went unrecognised.
Correction. Note that Mabo (1992) rejected terra nullius and recognised native title.
Markers reward an accurate definition tied to its concrete legal effect.
SACE 2022-style15 marksEvaluate the extent to which the Australian legal system has recognised Aboriginal and Torres Strait Islander law since 1788.Show worked answer →
An extended-response question wants a sustained, evaluative argument with a judgement, not a description.
Contention. Argue that recognition has been limited and late: customary law was ignored for over two centuries before partial recognition through the courts.
Evidence of non-recognition. The reception of English law, the fiction of terra nullius, and the treatment of the colonies as settled.
Evidence of change. Mabo (1992) rejecting terra nullius, the Native Title Act 1993 (Cth), and the limited scope of native title where connection is maintained and not extinguished.
Judgement. Conclude that recognition is real but partial and conditional, weighing tradition against the law's capacity to correct historical wrongs.
Markers reward a clear contention, accurate authority and a reasoned evaluation.
