Short answer: In NSW, covering asbestos with plasterboard isn’t automatically a criminal offence on its own — but it’s the wrong first move, and doing it can quickly put you on the wrong side of the law. SafeWork NSW’s clear position is that if you’re renovating a home in Sydney, asbestos should be removed before the work starts, because removal is almost always “reasonably practicable.” Boarding over it is only meant to happen in exceptional cases. And if you disturb the asbestos while fixing plasterboard to it, or you hide it and create a future hazard, you can breach the Work Health and Safety Regulation 2017 and face serious penalties.
Let’s unpack what that really means for your Sydney property — in plain English.
TL;DR
- Covering asbestos with plasterboard is not the recommended or default legal approach in NSW.
- Under the WHS Regulation 2017 (Clause 457), asbestos likely to be disturbed during residential refurbishment must, so far as is reasonably practicable, be removed before work starts.
- SafeWork NSW’s official position: removal is “reasonably practicable” on most occasions, so covering over it usually won’t fly.
- Installing external cladding over asbestos is illegal in NSW — the asbestos must be professionally removed first.
- Screwing or nailing plasterboard into asbestos sheeting can disturb fibres and cause an offence, plus a genuine health risk.
- The safe, compliant path is testing, then licensed removal by a professional such as X-Asbestos Removalist Sydney.
What Does NSW Law Actually Say About Covering Asbestos?
Here’s the part that trips people up. There isn’t a single line in NSW law that says “thou shalt not put plasterboard over asbestos.” So people assume it’s fine. It isn’t that simple.
The rules live in the Work Health and Safety Regulation 2017. Clause 457 deals with refurbishing homes. It says that when you renovate, any asbestos that’s likely to be disturbed must be identified, and — so far as is “reasonably practicable” — removed before the work begins.
That phrase “reasonably practicable” is doing a lot of heavy lifting. SafeWork NSW has stated plainly that it considers removal to be reasonably practicable on most occasions. In other words, the default expectation is: take the asbestos out first. Covering it up is treated as the exception, not the rule.
So while boarding over asbestos isn’t spelled out as a crime by itself, choosing to cover instead of remove — when removal was practical — can put you in breach of your duties under the regulation.
Is It Illegal to Cover Asbestos With Plasterboard, Then? A Straight Answer
Let me give you the honest, non-lawyer version (and yes, this is general information, not legal advice — always check with SafeWork NSW or a licensed professional for your specific job).
Internally, covering non-friable asbestos sheeting with plasterboard sits in a grey zone. It isn’t automatically banned, but:
- If you disturb the asbestos to fit the board — drilling, screwing, nailing, cutting — you can release fibres and breach the regulation.
- If removal was reasonably practicable and you covered instead, you’ve likely gone against SafeWork NSW’s stated position.
- You’re hiding a hazard. The next owner, tradie, or renovator may drill into it years later with no idea it’s there.
Externally, it’s clearer: it is illegal to install cladding over any exterior material containing asbestos in NSW. All asbestos must be removed and disposed of by a licensed removalist first.
So “is it illegal to cover asbestos with plasterboard in NSW?” The safest and most accurate answer is: it’s strongly discouraged, often non-compliant, and the law expects you to remove it first. Treating “cover it up” as your Plan A is asking for trouble.
Why Covering Over Asbestos Is Usually a Bad Idea
A quick real-world picture. A Sydney homeowner in a fibro house from the 1970s decides to “freshen up” a hallway. Rather than pay for removal, they screw plasterboard straight over the old asbestos-cement wall sheets. Job done, right?
Not quite. Here’s what actually happens:
- Every screw hole disturbs the sheet. Drilling into asbestos-cement releases invisible fibres — exactly the ones linked to mesothelioma, asbestosis and lung cancer.
- The asbestos is now hidden. It’s off the asbestos register (if there even is one), out of sight, and forgotten.
- The next renovation is a landmine. A future tradesperson cuts into that wall expecting normal plasterboard and gets a face full of asbestos dust.
SafeWork NSW specifically warns that over-cladding creates a risk of breakage and contamination, and of the material being hidden and disturbed during future works. Those aren’t hypothetical worries — they’re the exact reasons the regulator pushes removal-first.
When Is Covering or Sealing Asbestos Allowed?
There are limited situations where not removing asbestos is the safer choice. If asbestos is in good, stable condition and removing it would actually create more disturbance and risk than leaving it, then controlling it in place — through proper encapsulation or enclosure by qualified professionals — can be the compliant option.
The order of preference under the rules is essentially:
- Remove the asbestos (the default expectation).
- If removal genuinely isn’t reasonably practicable, enclose it.
- If that’s not practicable either, seal (encapsulate) it.
Note what this list is: a professional risk-control hierarchy, documented in the building’s asbestos register and done to the SafeWork NSW Code of Practice. It is not the same as a weekend DIY job screwing plasterboard over a wall to save money. The distinction matters a lot legally.
Do You Need a Licence to Remove Asbestos in NSW?
This is where the numbers come in.
- You can legally remove up to 10 square metres of non-friable (bonded) asbestos yourself without a licence — but you must follow strict safety precautions.
- Removing more than 10 square metres of non-friable asbestos must be done by a licensed asbestos removalist.
- Friable asbestos (the crumbly, higher-risk type) must always be removed by a specially licensed removalist under a permit.
For most Sydney renovations, walls and ceilings add up to well over 10 square metres fast. That’s why so many homeowners end up needing a licensed professional anyway — and why “just board over it” is rarely the shortcut it appears to be.
If you’re weighing this up, our guide to asbestos removal cost in NSW breaks down the real numbers, and bonded (non-friable) asbestos removal explains what a compliant job looks like.
How Do You Even Know If It’s Asbestos?
You often can’t tell by looking. Asbestos was extremely common in Sydney homes built or renovated before 2003, when its manufacture and supply were banned in Australia. It hides in fibro wall sheeting, ceilings, eaves, splashbacks, vinyl floor tiles, and the backing behind electrical meter boards.
The only reliable way to confirm it is laboratory testing of a sample by a NATA-accredited lab. That’s step one before any renovation decision — including any decision about covering versus removing. You can arrange asbestos testing and inspection before you touch a single wall.
What About Disposal? (Because Covering Doesn’t Make It Disappear)
Even if you were tempted to cover asbestos, remember: it’s still there, and one day it has to go. NSW disposal rules are strict:
- Asbestos waste must be double-wrapped in heavy-duty plastic and clearly labelled.
- It must go to a facility licensed to accept asbestos — never your household bin.
- Illegal dumping carries enormous penalties, running into the hundreds of thousands and beyond.
Covering it up just delays this problem and often makes the eventual removal messier and more expensive. Doing it properly the first time is cheaper than doing it twice.

Frequently Asked Questions
Is it illegal to cover asbestos with plasterboard in NSW?
It’s not a standalone crime, but it goes against SafeWork NSW’s removal-first position and can breach the WHS Regulation 2017 if the asbestos is disturbed or if removal was reasonably practicable. External cladding over asbestos is illegal.
Can I just paint or seal asbestos instead of removing it?
Encapsulation is a recognised control method, but it’s a regulated, documented process done by professionals — not a DIY alternative to removal, and not the default option.
How much does asbestos removal cost in Sydney?
It depends on the type, quantity, and access. See our detailed asbestos removal cost guide for realistic figures.
Do I need a licensed removalist?
For more than 10 square metres of non-friable asbestos, yes. For friable asbestos, always.
The Bottom Line
Covering asbestos with plasterboard in NSW might feel like the quick, cheap option — but the law leans hard toward removing asbestos first, and covering it can create legal exposure, health risks, and a hidden problem for the future. When in doubt, test it, then let a licensed professional handle it properly.
