The task is narrower than it first looks. You already know a Commonwealth Act or regulation exists, and you want to know what has changed inside it since it started: which provisions were altered, when the change took effect, and which version of the text you should be quoting today.
This guide covers how to do that with the Federal Register of Legislation, what the Register can and cannot tell you, and the questions worth taking back to an official source before you rely on what you found.
Start with the authorised source
The Federal Register of Legislation describes itself as the authorised whole-of-government website for Commonwealth legislation and related documents. That word "authorised" is the reason to begin there rather than with a summary, a news article or a secondary legal site. An authorised register is the government's own published record of what the law says, and it is the version other people will expect you to have used.
Practical interpretation: treat any other source as a lead, not an answer. If a summary and the Register disagree, the Register is the one to quote, and the disagreement is itself worth noting.
What the Register actually gives you
According to legislation.gov.au, the Register contains the full text and details of the lifecycle of individual laws and the relationships between them. It also offers email notification of updates or changes to Commonwealth law based on your preferences, custom searches, and the ability to save items to your profile so you can reference them quickly later.
That maps neatly onto the two halves of tracking amendments:
- Reading the record — the full text, plus the lifecycle and relationship information that shows what has touched a law.
- Keeping up to date — email alerts and saved items, so you are notified rather than having to re-check manually.
Most people do the first and skip the second, which is why they discover a change months after it started.
A workflow that works
1. Find the law by its exact title. Search the Register for the Act or regulation using its formal short title. Precision matters: amending laws usually carry their own titles and years, so searching loosely returns a mix of the original law, the amending laws and unrelated material.
2. Note which version you are looking at. Before reading anything else, record the date you accessed the Register and how the site identifies the text you are viewing. If you later need to show what the law said on a particular day, that record is the difference between a citation and a guess.
3. Use the lifecycle and relationship information to find what has touched it. The Register states it holds details of the lifecycle of individual laws and the relationships between them. This is where an amending Act becomes visible: an amendment is typically a separate law that stands in a relationship to the one it changes. Work outward from the law you care about to the laws connected to it.
4. Read the amending law, not just the entry about it. The amending law is where the actual operative text sits, and its own provisions govern when the change takes effect. A change can be made on one date and start on another, so "Parliament changed it" and "the change applies now" are separate questions.
5. Set an alert and save the item. Create a profile, save the law to it, and set email notification preferences for it. This converts a one-off lookup into ongoing monitoring without you having to remember to check.
Why "the Act" is usually two documents
A common source of confusion: an amendment to an Act is generally made by a different, later Act. The original Act may still carry its original name and year, while the change lives in a separate law with a different name and year.
Practical interpretation: when someone says "the law was amended", ask which law did the amending. Then check three things separately — what the amending law changed, when it received assent or was registered, and when it commenced. Those are different dates and they answer different questions.
The same applies in reverse. If a provision seems to have disappeared, it may have been repealed, replaced or renumbered rather than removed silently. The relationship information on the Register is the place to confirm which of those happened.
Regulations are not the same tracking job
If the law you are following is a regulation or other legislative instrument, track it separately. The Register covers Commonwealth legislation and related documents, so instruments sit within reach of the same search — but an amendment to an Act does not automatically amend the regulations made under it.
Practical interpretation: if your question is about an obligation in practice rather than in principle — a form, a threshold, a reporting requirement — the regulation may be the more important document to monitor, and it may change on its own schedule.
Limits worth knowing before you rely on a result
| What you are checking | Where to look | What to verify |
|---|---|---|
| Current wording of an Act | Full text on the Register | The date you accessed it and how the version is identified |
| What changed it | Lifecycle and relationship details | Whether the change has commenced, and from when |
| Whether regulations changed too | The related regulations on the Register | Whether the Act amendment flowed through to the instrument |
| Staying informed | Email notification preferences and saved items | That your alert covers the specific law, not a broad category |
Two further limits matter. First, the Register covers Commonwealth legislation. If the law is made by a state or territory, it sits on that jurisdiction's own register, and you should confirm which level of government made the law before you search. Second, if your question is genuinely historical — "what did section X say on 1 July last year?" — the current text will not answer it, and you should confirm how to obtain the version that applied at that time.
Next steps
- Go to legislation.gov.au and search for the Act or regulation by its exact title.
- Open the current text and write down the date you accessed it and how the site identifies that version.
- Follow the lifecycle and relationship information to identify any amending laws, then open the amending law itself.
- Check when each change takes effect, not just when it was made.
- Create a profile, save the law, and set email notifications for it so future changes reach you.
- Re-check the Register before you quote, cite or act on any provision.
If a decision with legal, financial or regulatory consequences depends on the answer, confirm it with the agency that administers the law or with a qualified legal practitioner before acting.
