What silicosis is
Silicosis is an irreversible fibrotic lung disease caused by inhaling respirable crystalline silica (RCS) dust. Three clinical patterns:
- Chronic / simple silicosis — develops 10 to 30+ years after exposure to relatively low silica concentrations
- Accelerated silicosis — develops 5 to 10 years after intense silica exposure (typical of engineered stone benchtop work)
- Acute silicosis — develops within months to a few years of extreme exposure; often rapidly fatal
Silicosis is associated with elevated risks of lung cancer, autoimmune diseases (scleroderma, rheumatoid arthritis, lupus), kidney disease, and tuberculosis.
The engineered stone crisis
From the early 2000s, engineered (artificial / reconstituted) stone became widely used for kitchen and bathroom benchtops in Australia. The product contains very high crystalline silica content — often 90%+, vs around 30% in natural granite.
Workers fabricating, cutting, grinding and polishing engineered stone — usually in small-shop stonemasonry businesses — were exposed to extremely high silica concentrations. Cases of accelerated and acute silicosis emerged from around 2015, often in workers in their 20s and 30s.
On 1 July 2024 Australia became the first country to ban the use, supply, manufacture and processing of engineered stone, in response to the public health emergency. The ban is prospective — it doesn't affect compensation rights for past exposure. Workers exposed before the ban retain full claim entitlements.
Who is at risk
Occupations with documented silicosis risk in Australia:
- Stonemasons, particularly those who worked with engineered stone benchtops
- Tunnellers (rail and road tunnel construction)
- Quarry workers and rock-crushing operators
- Sandblasters and abrasive blasting operators
- Foundry workers (sand moulds)
- Concrete cutters, concrete drillers, demolition workers
- Kitchen and bathroom installers who cut benchtops on-site
- Mine workers in silica-bearing rock
- Pottery and ceramic workers
Compensation pathways
Silicosis compensation in Australia draws from multiple systems:
- State workers compensation schemes — statutory benefits for diagnosed workers (icare Dust Diseases Care in NSW, WorkSafe Victoria, WorkCover QLD, etc.)
- Common-law damages claims against employers and occupiers who failed to provide safe systems of work
- Product liability claims against engineered stone suppliers and importers
- Dust Diseases Tribunal (NSW) for fast-tracked claims
- TPD insurance through super where the worker is permanently incapacitated — see TPD claim guide
Indicative compensation ranges:
| Disease severity | Indicative range |
|---|---|
| Simple chronic silicosis (early) | $80,000 – $200,000 |
| Simple chronic silicosis (advanced) | $200,000 – $400,000 |
| Accelerated silicosis | $300,000 – $700,000 |
| Progressive massive fibrosis | $500,000 – $1,200,000 |
| Silicosis with lung cancer | $700,000 – $1,500,000+ |
Claims involving young engineered stone workers commonly recover at the higher end of these ranges due to substantial future economic loss.
Claim process
- Diagnosis by respiratory physician with HRCT, pulmonary function testing, occupational exposure history
- Specialist silicosis lawyer engaged (no-win-no-fee)
- Statutory workers compensation claim lodged with the relevant state insurer (immediate medical and weekly benefits)
- Common-law / product liability claim prepared in parallel where appropriate
- Settlement negotiations with employers' insurers and product suppliers
- Tribunal or court resolution if settlement isn't reached
Time limits
Time limits run from the date of diagnosis or knowledge of disease causation, not from the date of exposure. Common limits:
- Workers compensation lodgement — 6 months from awareness of injury (most states), with extensions
- Common-law damages — 3 years from date of damage / discovery (varies by state)
- Product liability — 6 years from date of damage (Australian Consumer Law / state equivalents)
Late lodgement is often allowed for silicosis given the long latency. Don't assume you've missed deadlines without specialist advice.
