What is asbestosis
Asbestosis is a chronic, progressive fibrotic lung disease caused by inhaling asbestos fibres over a sustained period. Asbestos fibres lodged in lung tissue trigger an immune response that scars the alveoli (air sacs), progressively reducing the lungs' ability to transfer oxygen.
Symptoms typically include:
- Shortness of breath, initially on exertion, progressively at rest
- Persistent dry cough
- Chest tightness or pain
- Finger clubbing in advanced cases
- Reduced exercise tolerance
Most cases develop 20 to 40 years after the initial exposure period. Many claimants are first diagnosed in their 60s, 70s or 80s following exposures from the 1960s through 1980s.
Diagnosis pathway
- GP referral to a respiratory physician based on symptoms and exposure history
- High-resolution CT scan (HRCT) — the gold standard imaging for early asbestosis
- Pulmonary function tests (PFTs) — spirometry, lung volumes, gas transfer to quantify functional impairment
- Occupational history documenting periods, employers, and tasks involving asbestos exposure
- Specialist diagnosis report linking imaging findings, function results, and exposure history
The diagnosis report is the foundation of the claim. A respiratory physician with experience in dust disease cases will produce a report addressing not just the clinical findings but also the causation linkage required for the claim.
Who is most at risk
Sustained heavy exposure characterises asbestosis cases. Common occupational backgrounds:
- Asbestos mining, milling, and manufacturing (Wittenoom, Baryulgil, James Hardie facilities)
- Insulation work (pipe lagging, boiler insulation)
- Shipbuilding and ship repair
- Power station construction and maintenance
- Building trades — particularly demolition, asbestos cement (fibro) sheeting work
- Vehicle brake and clutch maintenance (asbestos-containing friction products)
- Railway workshop and locomotive trades
- Defence Force personnel exposed during shipbuilding, base maintenance, equipment repair
Compensation available
| Severity | Indicative range |
|---|---|
| Mild asbestosis (early imaging changes, FEV1 80%+) | $50,000 – $120,000 |
| Moderate asbestosis (clear functional impairment, FEV1 60–80%) | $120,000 – $280,000 |
| Severe asbestosis (FEV1 below 60%, oxygen dependent) | $280,000 – $500,000 |
Compensation typically includes general damages, past and future care, treatment costs, economic loss (where claimant is still of working age), and a separate component for tinnitus and complications where present.
Asbestosis claimants often have separate entitlements:
- icare Dust Diseases Care (NSW) — weekly payments and treatment
- Common-law claims against responsible employers or asbestos product manufacturers
- James Hardie AICF claims for former Hardie subsidiary exposures
- TPD insurance through super — see TPD claim guide
Disease progression and additional claims
Asbestosis is progressive in most cases. The compensation system recognises this — a claim resolved at one severity level can typically be revisited if the disease materially worsens. A specialist asbestos lawyer will structure the settlement to preserve the right to bring a fresh claim on deterioration.
Where asbestosis progresses to:
- Lung cancer — separate cancer claim, with substantially higher compensation
- Mesothelioma — separate mesothelioma claim, expedited procedures, urgent
New diagnoses do not merge with prior asbestosis claims. They are separately compensable.
Claim process
- Get a diagnosis confirmed by a respiratory physician with dust-disease experience
- Document occupational exposure history — employers, dates, specific tasks involving asbestos
- Engage an asbestos lawyer (typically no-win-no-fee for these claims)
- Lawyer identifies the appropriate forum (Dust Diseases Tribunal, state common-law, AICF, etc.)
- Statement of Claim filed; matter progresses through the relevant tribunal
- Most cases settle without trial; expedited procedures apply for terminal cases
