Managing Workers Compensation in Your Construction Business
Construction has one of the highest workplace injury rates of any Australian industry. That makes workers compensation not just a legal requirement but a genuine financial risk — one that small construction compliance businesses need to manage proactively.
Workers compensation in Australia is administered at the state and territory level, meaning your obligations depend on where your workers are based and where they work. Despite the variation, the core framework is consistent: you must have insurance, report injuries promptly, and support workers' return to work.
Getting any of these wrong creates legal exposure and, more importantly, can significantly worsen outcomes for injured workers — and increase your long-term premium costs.
Who Must Have Workers Compensation Insurance?
Workers compensation insurance is mandatory for employers in every Australian state and territory. You must hold a valid policy if you employ:
- Full-time or part-time employees
- Casual employees — including casuals who work infrequently
- Apprentices and trainees
- In some states, contractors who are deemed workers for workers compensation purposes (this varies significantly by state)
The contractor trap: In several states — including NSW, VIC, and QLD — certain contractors are deemed to be "workers" for workers compensation purposes even if they have an ABN and are genuinely running their own business. This typically applies where the contractor is engaged primarily for their labour and doesn't employ their own workers.
For construction businesses that engage sole trader subbies, this can mean you are required to cover those subbies under your workers compensation policy — even if they have their own public liability insurance. Check the deemed worker rules for your state and consult your workers compensation insurer.
State Workers Compensation Schemes
Workers compensation is managed through separate state schemes:
| State | Scheme / Regulator | | ----- | ------------------------------ | | NSW | icare (Insurance and Care NSW) | | VIC | WorkSafe Victoria | | QLD | WorkCover Queensland | | WA | WorkCover WA | | SA | ReturnToWorkSA | | TAS | WorkSafe Tasmania | | ACT | WorkSafe ACT | | NT | NT WorkSafe |
Some states have a single state insurer (QLD, VIC, WA); others allow private licensed insurers (NSW, SA). Your policy is issued by the insurer in the state where your workers are based.
If you work across state borders: You may need separate policies in each state, or a national policy that covers workers in all relevant states. Check with your broker.
How Premiums Are Calculated
Workers compensation premiums are calculated based on:
- Wages paid — your premium is a percentage of your total wages liability
- Industry classification — construction is a higher-risk industry, so base rates are higher than office-based businesses
- Claim history — businesses with a history of injury claims typically pay higher premiums (experience rating)
- Workplace size — larger businesses may have more complex premium calculations
Key implication: Your claims history directly affects your future premiums. A single serious injury claim can increase your premium for several years. This is why proactive injury prevention — through strong WHS practices — is not just an ethical obligation but a direct financial interest.
Your Obligations When a Worker Is Injured
When a worker is injured at work, you have a series of obligations that must be met promptly:
1. Immediate Response
- Ensure the worker receives appropriate first aid
- Call emergency services if required
- Do not disturb the scene of a serious incident (unless necessary to prevent further injury) — the WHS regulator must be notified of notifiable incidents before the scene is disturbed
2. Notify Your Insurer
You must notify your workers compensation insurer of any workplace injury. The timeframe for notification varies by state — check your policy, but in most states, you should notify as soon as reasonably practicable.
Do not delay notification — late notification can affect your obligations and the worker's access to benefits.
3. Complete the Incident Report
Document what happened, when, where, how, and who was involved. This record is important for:
- Your WHS incident investigation
- Your workers compensation claim
- WHS regulator notification (if the injury is notifiable)
4. Notify the WHS Regulator (if Notifiable)
Under the model WHS Act, you must immediately notify the WHS regulator if a workplace incident involves:
- Death of a person
- Serious injury or illness (defined to include: amputation, fractures, burns, loss of consciousness, damage to sight or hearing, hospitalisation, etc.)
- Dangerous incident (an incident that exposed persons to a serious risk, even if no injury occurred — e.g., collapse of scaffolding, uncontrolled release of hazardous substance)
"Immediately" means as soon as you know — this is a phone call, not a form. Written notification follows within 48 hours.
You must also preserve the site of a serious incident (to the extent reasonably practicable) until an inspector has attended or authorised disturbance.
Failure to notify a notifiable incident is itself an offence with significant penalties.
5. Develop and Implement a Return-to-Work Plan
Return to work is a key component of the workers compensation framework. As soon as the worker has a medical certificate and is recovering, you are expected to work with them and their treating practitioner to develop a return-to-work plan.
The plan identifies:
- The worker's current work capacity (hours, types of duties they can perform)
- Suitable modified or alternative duties available within the business
- How the plan will be monitored and adjusted over time
Why this matters: Early return to work — even in a modified capacity — significantly improves injury recovery outcomes. It also reduces the duration of your workers compensation claim, which directly affects your premium.
Large employers (typically 20+ employees in most states) must have a formal Return to Work Coordinator. Small businesses have less prescriptive requirements but still have duties to facilitate return to work.
Portable Long Service Leave in Construction
Most states with significant construction industries have portable long service leave schemes specifically for construction workers. These operate separately from the standard long service leave framework under state long service leave legislation.
| State | Scheme | | ----- | ------------------------------------------------------------------------ | | VIC | CoINVEST | | NSW | Long Service Corporation (Construction Industry) | | QLD | Building & Construction Industry (Portable Long Service Leave) Authority | | ACT | ACT Long Service Leave Authority (Construction) |
Under these schemes:
- Employers pay levies to the scheme fund based on wages paid to construction workers
- Workers accrue long service leave entitlements through the scheme, not through individual employers
- When a worker takes long service leave, they claim from the scheme — not from their individual employer
This means that when a construction worker moves from one employer to another (as is common in the industry), they don't lose their long service leave entitlements.
Registration obligation: You must register as an employer with the applicable portable LSL scheme in each state where your construction workers are based. Levy payments are typically quarterly.
Failure to register and pay levies is a significant and often overlooked compliance risk for small construction businesses.
Keeping Your Premium Under Control
Beyond complying with the legal framework, proactive management of your workers compensation obligations can reduce your premium:
- Strong WHS practices reduce injuries, which reduces claims, which reduces your experience-rated premium
- Prompt incident reporting ensures claims are managed efficiently, reducing claim duration
- Active return-to-work support gets workers back sooner, reducing compensation payments
- Accurate payroll reporting ensures your premium reflects your actual wages, not overstated estimates
- Review your industry classification — if your business has changed and your work now falls into a different risk classification, your premium category may be wrong
