Silica Dust Regulations in Queensland: What Every Employer Must Know in 2026

Queensland has some of the most active silica enforcement in Australia — making it essential that businesses understand their silica dust monitoring obligations in Queensland — and for good reason. The state’s construction boom and dominant mining sector mean more workers face silica exposure risk here than almost anywhere else in the country. If your business operates in Queensland, here is exactly what the law requires and what you must do to stay compliant.

The Legislative Framework in Queensland

Queensland operates under two distinct regulatory frameworks for silica dust, depending on the industry:

General workplaces (construction, manufacturing, civil works, stone fabrication) are governed by the Work Health and Safety Act 2011 (QLD) and the Work Health and Safety Regulation 2011 (QLD), as amended by the Work Health and Safety Amendment Regulation 2024 — which adopted the national Chapter 8A crystalline silica provisions effective 1 September 2024.

Mining and quarrying operations fall under the Mining and Quarrying Safety and Health Act 1999 (QLD) and the Coal Mining Safety and Health Act 1999 (QLD), overseen not by WorkSafe QLD but by Resources Safety & Health Queensland (RSHQ) — which also sets requirements for silica monitoring for Queensland mining operations beyond the general WHS framework. Mining employers have a separate and in some respects more stringent set of obligations.

This dual-framework structure is unique to Queensland and a common source of compliance confusion, particularly for contractors who work across both general construction and mine sites.


WorkSafe Queensland: Chapter 8A Requirements

Under Chapter 8A of the WHS Regulation 2011 (as amended), Queensland PCBUs who direct workers to process crystalline silica substances (any material containing ≥1% crystalline silica by weight) must:

Risk Assessment

Conduct a risk assessment before processing begins and whenever work conditions, materials or processes change materially. The assessment must determine whether the work is high-risk silica processing — a specific classification under the regulations with additional obligations attached.

Silica Risk Control Plan

If processing is assessed as high-risk, the PCBU must prepare a written silica risk control plan before work commences. The plan must document identified risks, selected control measures, how those controls will be monitored and maintained, and the arrangements for air monitoring and health monitoring.

Accredited Training

Workers who perform or directly supervise high-risk silica processing in Queensland must hold a nationally recognised crystalline silica training credential. This training must be conducted by an accredited RTO and is mandatory — not optional — under the amended regulation.

Air Monitoring

Queensland employers must conduct air monitoring for respirable crystalline silica where they cannot confirm with certainty that worker exposures remain below the WES of 0.05 mg/m³. Where monitoring reveals exceedances, results must be reported to WorkSafe Queensland.

WorkSafe QLD has published guidance confirming that air monitoring should be conducted by a competent person — in practice, a certified occupational hygienist using equipment calibrated to Australian Standard AS 2985 and a NATA-accredited laboratory for analysis.

Health Monitoring

Workers engaged in ongoing high-risk silica processing must be provided with health monitoring — covering baseline chest X-rays, lung function tests, and periodic respiratory reviews — at the employer’s cost.

QLD Code of Practice — Construction and Manufacturing

The Managing Respirable Crystalline Silica Dust Exposure in Construction and Manufacturing of Construction Elements Code of Practice 2022 is Queensland’s primary practical guidance document for construction employers. Compliance with this Code of Practice is the accepted way to demonstrate compliance with the legislative requirements. Key provisions include:

  • Hierarchy of controls with specific engineering control requirements for each high-risk task (cutting, grinding, drilling, jackhammering)
  • Mandatory use of on-tool water suppression or on-tool extraction for dry cutting and grinding
  • Monitoring trigger points — when air monitoring is needed and how frequently

RSHQ: Mining and Quarrying Requirements

For Queensland mines and quarries, Resources Safety & Health Queensland (RSHQ) is the primary regulator. Mining operations have obligations under the Mining and Quarrying Safety and Health Act 1999 that exist in parallel — and sometimes exceed — the general WHS requirements.

QGL02 Guideline

Queensland’s QGL02 Guideline for Management of Respirable Dust in Queensland Mineral Mines and Quarries is the key technical document for mining operations. From 1 September 2020, the occupational exposure limits under this guideline are:
– Respirable dust: 1.5 mg/m³ (8-hour TWA)
– Respirable crystalline silica: 0.05 mg/m³ (8-hour TWA)

The QGL02 specifies monitoring methodology, frequency, competency requirements, reporting obligations, and the action levels that trigger escalating responses from site management.

Mine Record Entry and Reporting

Mining site senior executives (SSEs) in Queensland have specific obligations to record dust monitoring results in the Mine Record and to notify RSHQ when exposures exceed prescribed limits. These obligations are enforced independently of the general WHS Act.


The December 2026 WEL: Queensland Implications

From December 2026, Australia’s WES for respirable crystalline silica becomes a WEL — carrying stronger enforcement provisions and, potentially, a tighter numerical limit. For Queensland mining operations, this may also affect QGL02 thresholds, pending guidance from RSHQ.

Queensland employers in both general industry and mining should treat the period between now and December 2026 as a compliance preparation window: establish your baseline through air monitoring, confirm your controls are working, and document everything.

Frequently Asked Questions

Who regulates silica dust in Queensland construction?

WorkSafe Queensland (also known as Workplace Health and Safety Queensland) regulates silica under the Work Health and Safety Act 2011 (QLD) and the amended Chapter 8A regulations. For construction sites, the relevant guidance document is the Silica Code of Practice for Construction and Manufacturing.

Who regulates silica in Queensland mines and quarries?

Resources Safety & Health Queensland (RSHQ) regulates silica in mines and quarries under the Mining and Quarrying Safety and Health Act 1999 (QLD). RSHQ has its own monitoring guidelines (QGL02), reporting requirements, and enforcement powers that apply in addition to — and sometimes instead of — general WHS provisions.

Is the silica Worker Register required in Queensland?

As of 2026, Queensland has not implemented the same Silica Worker Register as NSW (which requires employer notification from October 2025). However, health monitoring records must be maintained for 40 years (Regulation 426Q) and made available to workers; air monitoring records are retained for 30 years (Regulation 426K). Requirements may change — monitor WorkSafe QLD guidance regularly.

What happens if I don’t comply with Queensland silica regulations?

Non-compliance with Chapter 8A can result in WHS infringement notices, improvement notices, prohibition notices, and prosecution. For mining operations, RSHQ has separate enforcement powers. Penalties under Queensland WHS legislation can reach hundreds of thousands of dollars per breach, with personal liability for officers.
