Why is demolition licensing different depending on where your business works?
Demolition licensing in Australia is not one national system, it is set state by state, so a demolition contractor who has their compliance sorted in one state can find a different rule waiting the moment they bid a job across the border. Most owners only discover this gap once a quote is already on the table and the structural and machinery requirements for that site do not match what their licence currently covers.
A demolition contractor working out of Perth, Sydney, Brisbane, Melbourne, Hobart or Darwin sits under a different regulator with a different definition of what counts as licensed work, a different class system, and different conditions tied to the height or loadbearing nature of the structure and the kind of machinery involved, such as excavators, cranes or skid steer loaders. None of that is a formality. In the states that license demolition work, doing that work without the right licence is treated as an offence, not an oversight.
What licence does a demolition contractor need in Western Australia?
In Western Australia, WorkSafe sets two types of demolition licence, Class 1 and Class 2, each valid for a period of three years and endorsed with conditions tied to how the work must be carried out. If your business works on a structure above a certain height that is not a simple single storey dwelling, or a fence or wall above a certain height, you are likely to need one of these before you put a price on the job.
According to Demolition - WorkSafe, it is an offence to carry out Class 1 or Class 2 demolition work without holding the matching licence. The page sets out the current height thresholds and conditions, and those details are worth checking directly rather than relying on what was true the last time your business applied.
What about New South Wales, Queensland, the Northern Territory and other states?
Outside WA, the pattern repeats with different names. New South Wales runs a restricted and an unrestricted demolition licence, Queensland requires a demolition work licence for most structural work involving machinery such as excavators or cranes, Victoria registers demolishers across three classes tied to building height, and Tasmania ties responsibility to a licensed builder. The Northern Territory does not license demolition work at all, but it still requires the regulator to be notified before the job starts.
According to SafeWork NSW, the unrestricted licence is needed where the work involves loadbearing structure, tower or heavy mobile cranes, pre or post-tensioned components, floor propping or explosives, and eligibility includes holding an ABN or ACN and naming a supervisor with the relevant demolition qualifications. The ABLIS NSW demolition licence page sets out the restricted licence that sits below it. In Queensland, WorkSafe QLD's demolition work licence page explains that a domestic house and its ancillary structures can be carved out of the licensing requirement where none of the higher risk methods or load shifting machinery are involved. In the Northern Territory, the NT WorkSafe demolition notification guide confirms there is no licence requirement, only a duty to notify the regulator before the job starts where the demolition involves a loadbearing structure above a set height. Victoria's registration is covered on the ABLIS Victoria demolisher registration page, and Tasmania's responsible person rule sits in the Building Act 2016, alongside the WorkSafe Tasmania Demolition Code of Practice which says a licence is required for some demolition work and that a principal contractor or demolition contractor should seek advice from the local regulator if unsure.
If your demolition business works in South Australia or the ACT, those details are not covered by the pages above, so check directly with that state or territory's work health and safety regulator before you quote.
Does a demolition licence also cover asbestos removal, salvage and other specialist work?
The pages above are about the demolition licence itself, not asbestos removal, salvage recovery or waste and recycling obligations, which generally sit under their own separate licensing and handling rules in each state. A demolition contractor pulling hazardous material such as asbestos out of a strip-out, or running a soft strip ahead of structural demolition, should treat that as a separate question from the demolition licence covered here.
This is general information, not legal, tax or employment advice. Check your own situation with the body named here or a qualified adviser.
What should a demolition contractor's own numbers say about licensing and compliance, instead of memory?
The number that tells the truth here is not the licence itself, it is the record behind it: which licence class covered which job, when it expires, which permits and neighbour notices were lodged, and which tipping dockets and waste and recycling records tie back to which site. Memory fades fast when a business is running several jobs with different councils, different neighbours and different machinery on site at once.
AI agents can carry that paperwork the way you would do it yourself. An AI agent is software that does a job your way, using your own wording, your own job numbers and your own rules, rather than a generic form filled in from memory weeks after the job wrapped up. A data first view of your licensing, permits and site safety records means the business always knows where it stands, instead of finding out at renewal time that a record was missed. AI agents can also flag when a job's scope, height or machinery needs a different class of licence before the quote goes out, not after the excavator is already on site.
Where can you check the current rules?

- Unrestricted demolition licence (NSW) - when the unrestricted licence is needed and eligibility to apply.
- ABLIS Demolition Licence (NSW) - the restricted demolition licence and the relevant Act and Regulation.
- Demolition work licence (QLD) - what demolition work requires a licence and the domestic house exemption.
- Guide Demolition notifications (NT) - confirms no licence requirement in the NT and the notification duty.
- ABLIS Registration of Building Practitioners - Demolisher (VIC) - the three classes of demolisher registration.
- Building Act 2016 (TAS) - responsible person for demolition work and licensed builder requirement.
- Demolition work Code of Practice (TAS) - guidance on when a licence is required and who to ask.
How does Data First Coaching approach this?
Data First Coaching, built by Greg Allan, starts from the demolition contractor's own job and compliance records before talking about licensing at all. It looks at which jobs carried which licence class, where permits and neighbour notices sat against the actual schedule, and where tipping, waste and recycling records tie back cleanly to the site they came from. Working through the Trade Business Intelligence, that picture usually shows whether a licensing gap is really about the licence, or about how records get captured on site in the first place. The how, including how agents are shaped for a particular demolition business, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member for every member.
