Short answer
Check the licence first — concreters need a licence for some work and not other work. Then check that the business is who it says it is: of the 734 Australian concreters in this directory, only 13.6% publish an ABN you can confirm, and 6.3% list a phone number that contradicts the one on their own website.
Concreters handle slabs, driveways, paths, footings, exposed aggregate, polished concrete and retaining work. This is what to check before you let one into your house, and what the evidence says about the category as a whole.
Concreters are licensed for some work and not others
Concreting is building work, and in most states it needs a trade licence or registration above a dollar threshold that differs by state — Queensland licenses concreting as its own class, New South Wales treats it as residential building work above its threshold, and structural slabs need engineering wherever you are. The regulator for your state is listed at the bottom of this guide.
There is no national licence register in Australia — each state and territory runs its own. The regulator for your state is listed at the bottom of this guide, and checking a number takes about a minute.
What 734 Australian concreters actually publish
We check every business in this directory the same way, and publish the result whether it flatters the trade or not. For concreters:
| What we checked | Concreters | All trades |
|---|---|---|
| Publish an ABN we could confirm | 13.6% | 21.2% |
| Listed phone matches their own website | 76.3% | 59.2% |
| Listed phone contradicts their own website | 6.3% | 7.7% |
| Website responded when we checked | 80.7% | 81% |
| Corroborated by two or more sources | 87.6% | 81.1% |
| Median number of Google reviews | 10 | 39 |
What goes wrong with concreters
- A slab poured without the engineering or the council approval the job required
- No written quote covering excavation, reinforcement and finish, so the extras arrive later
- Drainage left unaddressed, so water sits against the house
What to ask before the work starts
- What licence or registration do you hold for this work in this state?
- Does this job need engineering or council approval, and who arranges it?
- What reinforcement and thickness are you quoting, and is drainage included?
A concreter who answers all three of those without hesitating is telling you something useful. One who is vague about a licence number is telling you something too.
The median matters more than the average
The median concreter in this directory has 10 Google reviews. That is the number to hold in your head when you see a perfect five-star rating: five stars from four reviews and 4.6 from three hundred are not comparable, and the second is almost always the safer hire.
It is also why the ranking here weights review volume more heavily than review score. A business cannot buy its position, and a handful of glowing reviews does not move it far.
Where the concreters are
Brisbane (25), Melbourne (21), Sydney (20), Perth (18), Craigieburn (17), Joondalup (16). A shortlist for your own area is more useful than a national ranking — the best concreter in the country is no help if they are four states away.
Where to check a licence, by state
There is no national register. Search the licence number with the regulator for the state where the work is happening.

Common questions
- Do concreters need a licence in Australia?
- Sometimes. Concreting is building work, and in most states it needs a trade licence or registration above a dollar threshold that differs by state — Queensland licenses concreting as its own class, New South Wales treats it as residential building work above its threshold, and structural slabs need engineering wherever you are. The regulator for your state is listed at the bottom of this guide.
- How do I check a concreter's licence?
- There is no national register. Each state and territory has its own regulator — NSW Fair Trading, the Building and Plumbing Commission and Energy Safe Victoria in Victoria, QBCC in Queensland, Building and Energy in WA, Consumer and Business Services in SA, CBOS in Tasmania, Access Canberra in the ACT, and the NT Government. Search the licence number the business gives you on the regulator for the state the work is happening in.
- What percentage of Australian concreters have a verifiable ABN?
- 13.6% of the 734 concreters in this directory publish an ABN we could confirm against the national register, against 21.2% across all trades.
- How many reviews should a concreter have?
- The median concreter here has 10. Treat a five-star rating from a handful of reviews with more caution than a slightly lower rating from hundreds.
