Demolition looks simple from the street. An excavator arrives, a house comes down, and a block gets cleared in a day or two. Behind that machine sits a stack of paperwork, permits and safety obligations that decide whether a project runs on schedule or lands the builder in front of a regulator.
The pressure is rising. SafeWork agencies have put demolition businesses on notice following incidents like the Burwood partial building collapse in NSW. From March 2025, demolition licence holders in NSW must ensure workers complete prescribed training before starting licenced demolition work. Because individual licence classes carry distinct unit requirements, contractors should verify the current competency standards directly with SafeWork NSW. The regulatory direction is clear: more documentation, more removal, and stricter enforcement. For builders, developers and trades professionals, the projects that finish on time follow one pattern. Compliance work happens before the machinery arrives.
Start With Asbestos, Every Time
Homes built before the late 1980s and into the 1990s often contain asbestos in walls, eaves, roofing, floor coverings and fencing. As a result, a licenced assessor must inspect the property and a licenced removalist must clear any asbestos before major work begins. The numbers explain why regulators take this seriously. Asbestos-related diseases still claim roughly 4,000 Australian lives every year, which is more than double the national road toll. An estimated one in three commercial buildings in Australia still contains asbestos.
Furthermore, the Asbestos National Strategic Plan 2024–2030 is shifting the industry from managing asbestos in place toward proactive removal. Every demolition and renovation is now a compliance flashpoint. Disturbing suspect material without a licenced inspection exposes workers, neighbours and the principal contractor to serious health and legal risk. Accordingly, booking the inspection before any other work is organised should be standard practice on every project.
Abolish Utilities, Keep the Water On
Disconnection is a temporary state. Demolition, however, requires formal service abolishment, which means electricity, gas and telecommunications are completely cut off and sealed at the source by the relevant providers. This step is commonly overlooked, and it causes real delays. Abolishments can take weeks to schedule, so experienced operators lodge the requests as soon as the demolition decision is made. Water is the exception. Crews need it for dust suppression on site and for occupational health compliance throughout the job, so the water service should remain connected.
Permits: Apply Early, Budget Accurately
Local councils control demolition approval, and the requirements vary by jurisdiction. A standard permit package covers three key areas. First, a demolition permit is required from the local council or a private certifier. Second, building permits are needed where the demolition connects to a new build. Third, tree and asset protection approvals are required, covering street trees, footpaths, kerbs and council infrastructure. Costs vary widely. Residential demolition permits typically run $350 to $700 in Sydney and $200 to $300 in Brisbane, while complex projects in major cities can reach $500 to $2,000 depending on location and scope. Builders pricing a knockdown-rebuild need these figures in the quote from day one.
The 5-Day Rule: Notify the Regulator
Under harmonised Work Health and Safety laws, the contractor must notify the state WHS regulator, such as SafeWork, at least five days before demolition work starts. The rule applies when the structure is at least six metres high and load-bearing, or when load-shifting machinery operates on suspended floors. Industry compliance specialists describe this as one of the most commonly missed steps in the entire demolition process. Missing it triggers improvement notices, project delays and personal liability under WHS legislation. The notification takes only minutes to lodge, so skipping it is an unnecessary risk that puts the whole programme at risk.
Execution: Standards, Contractors and Paperwork
Once approvals are in place, execution needs to follow the national benchmark. AS 2601 (The demolition of structures) sets out controlled demolition methods for planners, engineers and contractors, prioritising the safety of site personnel, the public and adjoining properties. The 2001 edition served as the reference for over two decades, and AS 2601:2025 has now superseded it. Contractors should therefore confirm they are working to the current version. Beyond the standard, contractor selection matters significantly.
A licenced demolition specialist supplies a detailed Safe Work Method Statement (SWMS) for all high-risk work, a comprehensive demolition plan covering sequencing, exclusion zones and protection of neighbouring structures, and a waste disposal and recycling strategy with documented disposal points. The recycling component carries real weight. Australia’s construction and demolition sector achieves a 78 to 81 per cent recovery rate for building materials. Even so, around 6.4 million tonnes of concrete, asbestos, metals and timber still reach landfill each year. Councils and clients increasingly ask for recovery documentation, so a contractor who tracks waste streams protects the builder’s reputation as well as the environment.
The Step Nobody Talks About: Pest Control
Rodents and other pests scatter into neighbouring properties when a structure comes down. For that reason, many local councils require rodent and pest baiting before demolition begins, along with a pest clearance certificate as a condition of the permit. The baiting programme should be booked two to three weeks ahead of the scheduled demolition date. The treatment needs time to work, and the certificate must be in hand before the excavator moves in.
The Bottom Line
Demolition compliance in Australia follows a clear sequence. First, inspect and remove asbestos through licenced professionals. Next, abolish electricity, gas and telecommunications while keeping water connected. Then secure council permits and protection approvals early. After that, notify the WHS regulator at least five days out. Finally, engage a licenced contractor working to AS 2601, complete with a full SWMS, demolition plan and waste strategy, and arrange pest baiting before holding the clearance certificate.
Regulators are enforcing harder, asbestos rules are tightening and documentation expectations keep growing. Builders who treat compliance as the first phase of the project, rather than an administrative afterthought, clear their sites faster, protect their licences and keep their crews safe. In the current enforcement climate, that discipline is the real competitive advantage.
