How to Do Legal Research in Australia 2026

Legal research in Australia involves locating, interpreting, and applying legislation, case law, and secondary sources to address a legal problem. It typically involves identifying the legal issue, finding binding authorities, verifying their status, and synthesising legal doctrine. In Australian law schools, legal research is foundational for exams, legal reasoning, and clinical legal work.

This blog will introduce you to the basics of Australian legal research and how you can achieve all your academic goals at the very beginning of the semester.

Quick Summary: How to Do Legal Research in Australia

What Legal Research Really Means (And Why It’s More Than Finding Cases)

Of course, legal research is one of the main tasks of a law student, as it serves as a foundation for higher legal education and practice. However, aside from this, learning how to do legal research serves the following purposes as well:

1. Supports Legal Arguments

Lawyering is not all about answering exams, writing papers, or class discussions, as law schools tend to emphasise. The main job is to create legal arguments in favour of our clients, and to strengthen these, good legal research must be conducted to ensure the arguments are credible.

2. Builds Skills in Legal Application

Conducting legal research is not all about just typing keywords into a search engine. Legal research is also about identifying related keywords and phrases to explore concepts more deeply and meaningfully. Knowing how to conduct legal research builds our skills in relating what we know to what we seek to know.

3. Ensures Accurate Legal Application

Aside from building legal application skills, knowing how to conduct legal research ensures you engage deeply with your material. This means that you are capable of looking for the latest amendment or jurisprudence to the law or case you seek to cite. Practising good legal research can help you build this skill set.

Law students in Australia typically conduct research using AustLII, JADE, or library databases, and cite using the Australian Guide to Legal Citation (AGLC).

Why Legal Research Matters for Law Students and Legal Exams

Legal research matters for law students because it provides a good foundation for when they become full-fledged lawyers. As mentioned above, legal research is a very important and handy skill for a lawyer, and learning to conduct legal research early can help you do so.

Another reason why legal research matters for law students is that they use their research repository as their review materials for their upcoming law exams. The materials they have collected, whether they were used in research papers or not, are essential to ensuring that your answers to exams are accurate, updated, and credible.

The Authority Hierarchy in Australian Law (What Actually Counts)

Another essential skill to learn while exploring legal research is knowing the legal hierarchy in Australian law. This legal hierarchy helps law students discern which sources must be followed and applied, and which are merely persuasive. Even Courts use this legal hierarchy to decide pending cases more consistently:

Binding Authority: Those that Must be Followed

1. Legislation

Legislation is in the form of Acts passed by the Parliament, the legislative body of Australia, as well as regulations, rules, and bylaws. An example of this is the Native Title Act 1993, which seeks to recognise and protect a community’s native title and its co-existence with the national land management system.

2. Case Law from Higher Courts

Case law, on the other hand, is decisions promulgated by the Australian Courts, but specifically the High Court of Australia. More prominent case laws are Mabo v. Queensland (1991) which is notable for being the first Australian case to recognise the Native Titles of Indigenous Australians and Moorilla Estate Pty. Ltd. v. Lau (2024) which held as non-discriminatory the Lounge which only allowed women to enter because 'providing women with a space where they are advantaged countered the general societal disadvantage they experience'.

Persuasive Authority Only

1. Decisions from Lower Courts

Decisions from lower courts such as the Intermediate/Appellate Courts, Supreme Courts (Trial Division) of States/Territories, District/County Courts, and Magistrates/Local Courts are merely persuasive in nature, meaning they may merely guide the decisions of the higher courts but not dictate their outcomes.

2. Decisions from Other Jurisdictions

Each Australian State’s High Court may consider the decisions promulgated by another State’s High Court, but again, this cannot be binding but may only serve as a guide to their own promulgation. For instance, Tasmania’s High Court may consider decisions from the Intermediate Appellate Court of Queensland.

3. Secondary Sources

Secondary sources are books, articles, or clips made by credible legal authorities that explain, interpret, or comment on the law or the cases. Meagher, Gummow & Lehane, who wrote a commentary book on Equity Law, is one example of a credible legal author or commentary that Courts may use to inform but not bind their decisions.

Step-by-Step: How to do Legal Research in Australia

Now that you’ve identified the importance of conducting legal research in law school, it is time to learn how to do it well, step by step.

Identify the Legal Issue (The Start of Effective Legal Research)

Before inputting keywords for legal research in your preferred database, you have to understand what you want to research thoroughly. Read the legal issue or hypothetical presented to you & identify the legal concepts involved. Make a checklist of which ones you know something about, and start researching about knowledge gaps.

Setting up the correct legal issue is essential because it is the foundation for good legal research. It lays down the framework you are to follow for the rest of your legal research work.

Using Right Primary Authority and Legal Research Tools in Australia

The next step after identifying the legal issue you want to tackle is finding and sticking with a primary binding legal authority. As discussed above, these are either legislation created by the Parliament or decisions promulgated by the Australian Courts.

The main difference between the two is that legislation is written in general rules for everyone to follow, while cases are interpretations and applications of these general rules. With this distinction in mind, you can use legislation when there is no ambiguity involved in applying the law. At the same time, cases are helpful when the parties are in conflict over the interpretation of such legislation.

Another thing to take note of when finding research materials is how relevant they are to your central issue. A quick tip to help you with this is to map out your legal resources and determine how well they answer your legal research issue and its sub-issues. In that way, you can already eliminate material that you don’t really need to read up on.

Read With Purpose (Not Everything Matters)

Now that you’ve collected all the materials you need, next comes the most time-consuming part: reading & taking notes. Important tips to do this are highlighting and underlining the most pertinent parts so that you can eliminate further portions of the text that are not relevant to the question you want to answer. A very important thing to keep in mind is the legal issues and their sub-issues so that you prevent yourself from straying away from the topic you are conducting research on.

What Matters in a Case (And What You Can Ignore)

Mainly, there are 5 central portions of a case: facts, legal issue, ratio decidendi, obiter dicta, and concurring and dissenting opinions. Only 3 out of 5, mainly the facts, legal issues, and the ratio decidendi, are important to remember for purposes of conducting legal research.

Facts

Facts, or sometimes labelled as 'background' in Australian cases, contain the names of the parties, their pertinent information, and the situation which gave rise to the case at hand. This sets up the legal issue’s context, and as such, it is essential to take note of this because it helps you understand how the case came to be.

Legal Issue

The legal issue is the central problem the Court seeks to resolve for the parties involved. This is sometimes the most difficult to identify in cases because it is not readily apparent from the facts or background.

To help you determine the legal issue, you have to read the full text and choose the questions the Court answered through its ruling. That question is the legal issue involved in a particular case.

Ratio Decidendi

Arguably, the most essential part is the ratio decidendi or the legal principle or rationale that forms the binding legal basis for a court's decision. This is easily identified, especially when you already identified the legal issue the Court seeks to answer. Key phrases to look out for are 'the Court has established', 'the Court holds', or any other iterations of these phrases.

Obiter Dicta

Obiter Dicta or comments by the judges that are not related to the central issue the case/Court seeks to resolve are not binding. As such, although they are nice to note for class purposes, they are usually not relevant for legal research purposes and may even cause you to stray away from your central legal research question.

Concurring and Dissenting Opinions

Another portion of the case that does not matter most of the time is the separate opinions or concurring and dissenting opinions that other Judges have penned. In Mabo v. Queensland (1991), for instance, almost all the judges wrote separate concurring or dissenting opinions, as the case was highly controversial at the time.

Since these separate opinions do not form binding precedent, they can be read but not cited for legal research purposes.

How to Extract Legal Doctrine and Remember It Later

As can be seen above, the different portions of a case make it difficult to extract the ratio decidendi or the legal doctrine needed to summarise your legal research findings. As such, the following are just some tips to determine the legal doctrine of each case and remember them for purposes of the upcoming law school exams:

Start with the Legal Issue

Determine first the main issue the Court seeks to resolve. This is essential because it serves as the main framework that your research and legal doctrine will answer.

Take Note of the Court’s Resolution

After identifying the legal issue, take note of the Court’s decision answering such issue. The usual format of this resolution is 1) the Court’s identification of the legal resources (i.e. legislation, case, secondary sources) that justify their decision and 2) the application of such legal resources to the facts at hand.

Write the Doctrine in 1-2 Sentences

Now that you’ve got a question-answer format from the above steps, you can formulate the legal doctrine in an if-then format. For instance, in the case of Ferguson v. Kazakoff (2000), you can formulate the legal doctrine in the following manner:

IF a claimant alleges to have suffered from a 'mental or nervous shock,'

THEN prevailing jurisprudence requires proof of an abnormal condition of mind or body amounting to an injury, and not merely normal emotional responses or unpleasant memories.

Common Thinking Gaps Law Students Struggle With (But Aren’t Taught)

Law schools usually teach legislation and cases under a particular legal concept separately, leaving the analysis to their students. While this promotes independence, some students may get lost in the why and how of applying these legal resources to a particular case. Some other common thinking gaps include the following:

Missing other relevant legal resources
Failing to check whether a case or law is still 'good law'
Confusing ratio decidendi with obiter dicta

As such, it is essential to learn how to properly use legislation and cases to aid you in legal research and not as outcomes you just apply to your study without any other higher-level thinking involved.

Key Takeaways: How to Do Legal Research the Right Way

Legal research is a process that requires identifying legal issues, selecting the proper legal authority, and extracting legal doctrines.
A law student has to understand the legal authority hierarchy in Australia, where legislation and High Court decisions bind, while decisions of lower courts or courts of different jurisdictions, and secondary sources, merely persuade.
After collecting your legal materials, know which portions to focus on, such as the facts, legal issues, and ratio decidendi.
Legal AI tools can enhance (but not replace) legal reasoning by filling in thinking gaps by summarising cases, extracting doctrine, checking authority status, and saving time.
