Construction remains one of Brisbane’s most dynamic sectors, but it also carries significant health and safety risks. Meeting legal obligations under Queensland’s Work Health and Safety framework is non-negotiable for every business and worker on a site. This article outlines practical, actionable measures that principal contractors, subcontractors and PCBUs can adopt to maintain compliance, reduce incidents and protect people and projects.
Queensland’s regulatory framework and what it means on site
Queensland operates under the Work Health and Safety Act and associated regulations aligned with the model WHS laws. Workplace Health and Safety Queensland (WHSQ) enforces those obligations locally and issues codes of practice and guidance that are relevant to construction activities. The regime assigns duties to PCBUs (persons conducting a business or undertaking), officers, workers and other persons at a workplace. Understanding where responsibilities sit — and how regulators expect those duties to be discharged — is the first step to practical compliance on any Brisbane site.
WHS responsibilities: PCBUs, officers and workers
PCBUs must ensure, so far as is reasonably practicable, the health and safety of their workers and others affected by their work. Officers (e.g. directors or senior managers) must exercise due diligence to ensure the PCBU complies with its duties. Workers must take reasonable care for their own health and safety and cooperate with reasonable safety directions. On a construction site this translates to active supervision, competent planning, appropriate resourcing and a documented approach to identifying and controlling hazards.
Principal contractor obligations on Queensland construction projects
When projects involve multiple contractors, the principal contractor has a coordinating role and specific obligations. The principal contractor must set up and maintain an effective site safety management plan, ensure appropriate site inductions, coordinate safe work method statements (SWMS) for high-risk construction work, and establish emergency procedures. They must also ensure selection and supervision of subcontractors, maintain records of compliance, and provide workers with access to welfare facilities and first aid. If a project triggers high risk construction work categories — e.g. work at heights, underground work, or near live electrical conductors — the principal contractor must ensure written SWMS are prepared, followed and regularly reviewed.
Contractor compliance and subcontractor management
Contractors must demonstrate competency, hold required licences and comply with site rules and SWMS. Good practice starts at procurement: pre-qualification checks should confirm licences, insurances and a recent safety performance record. Once engaged, subcontractors must be integrated into the site’s safety systems via inductions, tool-box talks and routine supervisor engagement. The principal contractor should monitor subcontractor performance through inspections and audits and maintain a clear escalation process for non-compliance.
Conducting effective risk assessments on site
Risk assessment is not a one-off paperwork exercise. Effective risk management uses a staged approach: identify hazards, assess the level of risk, select controls based on the hierarchy (elimination, substitution, engineering, administrative controls, and PPE), implement controls, then review their effectiveness. Typical high-risk issues in Brisbane projects include falls from heights, moving plant interactions, electrical hazards, manual handling and asbestos. Focused, documented risk assessments tailored to each activity and revisited after incidents or changes to the work are essential to maintain safer outcomes.
Practical controls and systems that work in Brisbane projects
Implementing control measures that actually work day-to-day requires clear systems and leadership. Examples include a robust site induction that covers local risks, daily pre-starts and toolbox talks that address immediate hazards, permit systems for hot work or confined spaces, exclusion zones around plant, and documented handover procedures for shift changes. Regular maintenance and testing of plant and edge protection, plus clear asbestos management plans where relevant, are vital. Integrating digital tools for registering SWMS, recording inspections and tracking training can increase consistency and visibility of compliance across large sites.
Worker engagement, training and consultation
Regulators expect active consultation with workers about health and safety. This can be achieved through consultative mechanisms such as meetings, toolbox talks and appointing Health and Safety Representatives where requested. Competency-based training should be delivered before workers commence high-risk tasks and refreshed periodically. Practical mentoring and site supervision help translate training into safe behaviours. Where workers raise concerns, the PCBU must address them promptly and transparently to maintain trust and participation.
Incident reporting, investigation and continuous improvement
All incidents, near misses and injuries must be reported and, where required, notified to Workplace Health and Safety Queensland. Investigations should focus on root causes and systemic changes rather than blame. Documented corrective actions, follow-up audits and sharing lessons across projects are the mechanisms that turn incidents into long-term improvements. Regular safety performance reviews — including audits against the site safety plan and SWMS compliance checks — support an evidence-based approach to reducing risk.
When to use external support
Smaller contractors or complex projects often benefit from specialist advice to ensure systems meet regulatory expectations. Engaging an experienced advisor can speed up compliance, provide independent audits and help embed practical controls. For local projects, a competent Brisbane WHS Consultant can provide tailored guidance on SWMS, site safety plans and regulator engagement, ensuring you meet both the letter and spirit of Queensland WHS requirements.
Maintaining compliance in Brisbane’s construction sector is both a legal obligation and a business imperative. Clear allocation of responsibilities, robust risk assessments, active contractor management and ongoing worker consultation create safer sites and reduce the likelihood of costly incidents. By embedding practical systems and continually reviewing outcomes, principal contractors and PCBUs can deliver projects that protect people, timelines and reputations.
