Regulatory framework and who is responsible
Construction businesses in Brisbane operate under the Work Health and Safety Act 2011 (Qld) and the associated regulations, which implement the national model WHS laws. These set out the primary duties for persons conducting a business or undertaking (PCBUs), officers, workers and others at a workplace. In practice this means every party on a site — principal contractors, subcontractors, designers and specialists — has a defined role to prevent harm and must act so far as is reasonably practicable.
Principal contractor obligations in Queensland
The principal contractor (PC) carries a central coordinating obligation on multi-employer sites. That duty includes preparing and maintaining a site-specific WHS management plan, ensuring appropriate inductions and supervision, coordinating the management of hazards where multiple contractors interact, and providing site services such as first aid, emergency response arrangements and access controls. The PC must also ensure that high risk construction work is planned and controlled through Safe Work Method Statements (SWMS) and that permits, licences and plant registrations are current.
WHS responsibilities for businesses and officers
Under the Act, PCBUs must eliminate risks to health and safety where reasonably practicable, or if elimination is not possible, minimise risks using the hierarchy of control. Officers — including company directors and senior managers — have a duty to exercise due diligence to ensure the business complies with its WHS obligations. That includes having appropriate systems for monitoring compliance, allocating resources for safety, and ensuring staff have competency-based training.
Contractor compliance and managing subcontractors
Contractors must understand that compliance is not optional; they are PCBUs in their own right for the parts of the work they control. Practical compliance steps include providing competent personnel, maintaining plant and equipment, preparing SWMS for high risk activities (such as working at heights, crane operations, excavation and traffic management), and cooperating with the principal contractor’s site rules. Subcontractor selection should assess WHS performance, licences and insurance before engagement, and contractual arrangements should make clear WHS expectations and consequences for non-compliance.
Risk assessment and control: a step-by-step approach
Effective risk management begins during pre-construction planning and continues through project close-out. First, identify hazards through site surveys, design reviews and pre-start meetings. Second, assess the likelihood and consequence of each hazard to prioritise controls. Third, apply the hierarchy of control: eliminate the hazard if possible; substitute or isolate it; use engineering controls; implement administrative controls; and use PPE as a last resort. Document these decisions in the WHS management plan and in SWMS for specific tasks.
Practical tools: SWMS, pre-starts and toolbox talks
SWMS remain a cornerstone for high risk construction activities. They should be prepared before work starts, signed by the workers who will carry out the task and reviewed if conditions change. Daily pre-start briefings and toolbox talks reinforce expectations, surface emerging hazards and ensure everyone is aware of their responsibilities. Regular site inspections and audits verify that controls are working and create a record that can support continuous improvement.
Worker consultation and safety culture
Engaging workers and their health and safety representatives (HSRs) is not just a regulatory obligation — it is a practical way to reduce incidents. Consultation must be genuine: involve workers in risk assessments, method statement development and change management. A positive safety culture is fostered through visible leadership, accountability for safety outcomes, timely reporting and non-punitive handling of near misses so lessons can be shared across the workforce.
Specific Queensland considerations: notifications and enforcement
In Queensland, notifiable incidents (serious injuries, illnesses or dangerous incidents) must be reported promptly to Workplace Health and Safety Queensland and appropriate agencies. Inspectors have powers to issue improvement and prohibition notices, and prosecutions can result where duty holders fail in their obligations. Principal contractors should ensure incident investigation processes are thorough, that corrective actions are tracked to completion and that learnings are integrated into site procedures.
Training, competency and licensing
Competency requirements in construction are specific and often mandatory. Workers undertaking high risk roles must hold the correct tickets and licences, such as high risk licences for rigging, dogging and crane operation, or licences for electrical work. Ongoing training should include on-the-job mentoring, refresher courses and verification of competencies after periods away from critical tasks. Maintaining a training matrix and evidence of competencies simplifies compliance checks and audits.
Environmental and seasonal risks in Brisbane
Brisbane’s climate and urban environment create specific hazards — heat stress during summer, storm-related risks and traffic interactions in constrained inner-city sites. Principal contractors must consider these factors in rostering, hydration and rest facilities, stormwater and erosion controls, as well as traffic management plans that protect both workers and the public. Emergency plans should be tested for heat and severe weather scenarios.
Practical checklist for improving on-site compliance
To drive consistent compliance, use a short, targeted checklist: ensure the WHS management plan and SWMS are current; confirm licences and insurance for all contractors; complete site inductions for everyone on site; run daily pre-starts; conduct regular audits and toolbox talks; report and investigate all incidents and near misses; and maintain open consultation channels with workers and HSRs. Documentation and evidence of these activities are critical for demonstrating that steps were taken to manage risk.
Where to get specialist support
Many projects benefit from engaging external WHS advisors or consultants who understand Queensland legislation and the practicalities of construction. A local expert can help develop site-specific SWMS, conduct competent person reviews, train workers and assist with audits or incident investigations. For example, engaging a trusted Brisbane WHS Consultant can streamline compliance and provide practical recommendations that align with local regulator expectations.
Conclusion: embedding safety into delivery
Safety in Brisbane’s construction sector is achieved through clear allocation of duties, rigorous risk assessment, consistent contractor compliance and proactive principal contractor coordination. Rather than treating WHS as an administrative burden, embedding practical controls into everyday processes reduces incidents, protects workers and improves productivity. Consistent documentation, worker engagement and ongoing training ensure projects proceed with fewer interruptions and with confidence that legal and moral obligations are being met.
