| Article Type | Clinical & Legal Guide |
| Target Audience | Occupational physicians, health surveillance coordinators, HR managers, WHS managers, affected workers |
| Key Entities | Safe Work Australia, Comcare, state workers’ compensation schemes, state WHS regulators, Lung Foundation Australia |
| Regulations & Standards | Model WHS Act Part 3 — notifiable incidents; state workers’ compensation legislation; model WHS Regulations health monitoring notification requirements |
| Key Fact 1 | Occupational asthma claims must be lodged with the relevant workers’ compensation insurer within statutory time limits — typically within 6 months of diagnosis or 3 years of last exposure, depending on the state scheme. |
| Key Fact 2 | A confirmed silicosis diagnosis is both a notifiable WHS incident under state regulations and a trigger for comprehensive review of the employer’s silica monitoring and health surveillance programme. |
| Key Fact 3 | Occupational lung diseases are frequently missed or misattributed in clinical practice — workers presenting with respiratory symptoms should be asked about their occupational history by treating clinicians. |
| What This Covers | Disease types and their workplace causes, notification pathways (WHS regulators vs workers’ compensation), workers’ rights upon diagnosis, employer review obligations, ongoing surveillance of co-exposed workers |
| What This Does Not Cover | Social security and disability support pathways for workers unable to work, specialist respiratory medicine referral pathways |

Work-Related Respiratory Diseases: Recognition, Reporting and Compensation in Australia
Work-related respiratory diseases represent some of the most serious and preventable occupational health outcomes in Australia. From silicosis among stonecutters to occupational asthma in bakers, from mesothelioma among asbestos workers to coal workers’ pneumoconiosis in miners — these conditions cause permanent disability and premature death in workers whose exposures were knowable and whose diseases were preventable. Understanding how to recognise these conditions, fulfil notification obligations, and support affected workers through the compensation system is an obligation for every occupational health practitioner and WHS professional.
Major Work-Related Respiratory Diseases in Australia
Silicosis
Caused by inhalation of respirable crystalline silica (RCS). Three forms: simple silicosis (chronic, >10 years exposure), accelerated silicosis (5–10 years, heavier exposure, progressive massive fibrosis risk), and acute silicosis/silicoproteinosis (1–3 years, very high exposure — alveoli fill with protein-rich fluid, often rapidly fatal). All forms are irreversible. Diagnosis by chest X-ray (ILO B-reader classification) and clinical history. Notifiable under WHS regulations in all states and territories.
Coal Workers’ Pneumoconiosis (CWP)
Caused by inhalation of coal mine dust including crystalline silica. Simple CWP (coal macules/nodules) to progressive massive fibrosis. Re-emerged in Australia since 2015 — Queensland and NSW have specific CWP notification requirements. Managed through state mining regulator notification and the Coal Workers’ Health Scheme (Queensland).
Mesothelioma
Malignant pleural or peritoneal mesothelioma caused by asbestos fibre inhalation. Latency 20–50 years. Currently killing ~700 Australians annually. No effective curative treatment. Australia has one of the world’s highest rates due to historical asbestos use. All diagnoses are notifiable under WHS legislation and trigger investigation by relevant asbestos/WHS regulator.
Occupational Asthma
Work-induced asthma with sensitisation (occupational asthma) or exacerbation (work-aggravated asthma). Common causes: isocyanates, flour dust, wood dust, latex, laboratory animal allergens, hairdressing chemicals. Diagnosis requires objective evidence of reversible airway obstruction and temporal relationship with work (serial peak flow monitoring, specific bronchoprovocation challenge). Management requires removal from further sensitiser exposure.
Occupational COPD
Accelerated decline in FEV₁ from cumulative dust, fume and chemical exposure contributing to chronic obstructive pulmonary disease. Underdiagnosed as occupational component — many cases attributed entirely to smoking history. Significant contributory causes include mineral dust, welding fume, grain dust and coal mine dust.
Notification Obligations for Employers
WHS Regulator Notification
Under the model WHS Act and Regulations, and more specifically under the health monitoring requirements of Part 7.1, a PCBU must notify the relevant WHS regulator when health monitoring results reveal a work-related disease or condition. For respiratory diseases, this includes confirmed silicosis, confirmed CWP, confirmed mesothelioma and asbestosis. Notification timeframes are typically immediate to 48 hours for serious diagnoses. The PCBU must also notify the worker within a prescribed timeframe.
Workers’ Compensation Notification
Employers also have obligations under state workers’ compensation legislation to notify insurers and provide claim documentation when a worker claims compensation for a work-related disease. Workers’ compensation and WHS regulator notifications are separate processes through different agencies.
Workers’ Rights Upon Diagnosis
Workers diagnosed with a work-related respiratory disease have rights including:
- Right to receive a copy of their health monitoring results and have them explained
- Right to be referred to an occupational physician for specialist assessment and management advice
- Right to apply for workers’ compensation for medical expenses, lost earnings and impairment lump sum
- Right to remain in the workplace in a suitable role where medically possible (redeployment from further silica/asbestos exposure)
- Right to ongoing health surveillance to monitor disease progression, particularly for silicosis and CWP
Employer Review Obligations Following Diagnosis
When a worker is diagnosed with a work-related respiratory disease, the PCBU must not treat it as an isolated case. Obligatory actions:
- Review the relevant exposure controls and monitoring programme immediately — if one worker has silicosis, others in the same SEG are at risk
- Offer health surveillance to all workers in the affected SEG
- Review the adequacy of the current WES monitoring programme and control hierarchy
- Document all actions taken and report to the WHS regulator as required
- Review training and information provided to workers about the hazard
