Mould exposure compensation claims in Queensland

When mould exposure becomes a compensation claim

Living or working in a building with a mould problem is not by itself a claim. A claim for mould exposure compensation generally needs three elements:

• Someone responsible for the building knew or ought to have known about the problem.
• They failed to take reasonable steps to deal with it.
• That failure caused a diagnosed illness or condition.

Depending on the setting, the responsible party may be a landlord or property manager, an employer, a body corporate, a builder, or the owner or manager of a commercial or public building.

Where these claims arise

• Rental homes with persistent damp, roof or plumbing leaks, or flood damage that was never properly remediated
• Workplaces with water damage, contaminated air conditioning or poor ventilation
• Schools, hospitals, offices and other public or commercial buildings with known problems left untreated
• Apartments where a body corporate did not fix a leak from common property

Asbestos and silica are dealt with separately on the asbestos and mesothelioma and silica disease pages. Those claims run differently, and they are the centre of the firm’s dust disease specialty.

Mould illness: what the medical evidence supports

This is the central issue in almost every mould claim, so it is worth being direct.

Mould exposure can be associated with some conditions. The evidence is generally strongest for:

• Allergic reactions, including allergic rhinitis and eye irritation
• New or worsening asthma, including in children
• Hypersensitivity pneumonitis, an inflammatory lung reaction to inhaled organic particles, which can become chronic
• Allergic bronchopulmonary aspergillosis (ABPA), an allergic reaction to Aspergillus mould in the airways, most often in people who already have asthma or cystic fibrosis
• Fungal infections, such as aspergillosis, in people with weakened immune systems or existing lung disease

Beyond those, the picture is more contested. Fatigue, headaches, brain fog, joint pain and other systemic symptoms are real to the people who have them. They are also non-specific, and defendants routinely point to other explanations.

CIRS and “biotoxin illness”

Some practitioners diagnose chronic inflammatory response syndrome (CIRS), sometimes called biotoxin illness, and link it to mould in water-damaged buildings. Many specialists in Australia do not accept it as a distinct condition. In 2018, a federal parliamentary committee inquired into biotoxin-related illnesses. It heard from many affected people, and recommended further research and clinical guidelines for doctors rather than endorsing the diagnosis.

In a court claim, that matters. A claim resting only on a CIRS diagnosis is likely to be strongly disputed by the defendant’s specialists. It is not automatically hopeless, but it is expensive and uncertain to prove.

What makes a mould illness claim viable

A viable claim usually has medical evidence connecting a specific exposure to a specific, recognised condition, supported by a clear and documented timeline. Symptoms that began or worsened during the exposure, and improved when you left the building, are often important. So are treating doctors’ notes made at the time.

The evidence a mould illness claim needs

The notification trail. Written complaints and the responses to them are the backbone of a claim, because they show what the responsible party knew and when. Emails, text messages and maintenance portal requests all count. If a complaint was only made verbally, record it in writing afterwards, even late.

Building evidence. Entry condition reports, inspection reports, remediation quotes and invoices, maintenance records, dated photographs and any air or surface testing. Testing by a qualified occupational hygienist or building biologist carries more weight than a home test kit.

Medical evidence. GP and specialist records made during the period of exposure, and independent specialist opinion connecting the condition to the exposure rather than to another cause. Respiratory physicians, immunologists and occupational physicians are the usual specialists.

Loss evidence. Time off work, reduced hours, medical expenses and the practical effect on daily life. These are what a damages claim is ultimately measured by.

If that evidence is not there, an honest early assessment saves time and money. If it is, the claim is assessed like any other negligence claim.

Who may be responsible for mould

The right defendant depends on who controlled the building and who knew about the problem.

• Landlords and property managers. A landlord has obligations under Queensland tenancy law and a general duty to take reasonable care for the safety of tenants. A property manager who received complaints and did not pass them on or act on them may also be relevant.
• Bodies corporate. Where water came from common property, such as a roof, balcony membrane or shared plumbing, the body corporate is usually responsible for the repair.
• Employers. An employer must provide a safe workplace, including safe air, under work health and safety laws and the common law.
• Occupiers of public and commercial buildings. Schools, hospitals, shopping centres and offices are generally expected to deal with known hazards to the people who use them.
• Builders and designers. Defective waterproofing, drainage or ventilation can be the root cause. Claims against builders raise separate questions about building contracts, statutory warranties and time limits, and they are often about property damage rather than health.

More than one party can share responsibility. A property manager may blame the owner, and an owner may blame a builder. Working out who should answer the claim is part of the early work.

What mould exposure compensation can cover

A successful damages claim is measured by the effect of the diagnosed condition on your life. Depending on the evidence, it can include:

• Pain and suffering, including the effect of the condition on your daily activities. In Queensland this is assessed on a statutory scale under the Civil Liability Act 2003 (Qld).
• Past and future loss of earnings, where the condition kept you off work or reduced your capacity.
• Medical and treatment costs, including specialist appointments, medication and ongoing care.
• Care and assistance provided by others, where it meets the thresholds that apply.

Some losses belong elsewhere. Damaged furniture, clothing and belongings, relocation costs and rent reductions are usually pursued through the tenancy dispute or against the building owner as property claims, not as part of the compensation claim for illness.

Where the condition resolves once you leave the building, the claim is usually modest. Where it becomes chronic, such as long-term asthma or hypersensitivity pneumonitis, it can be more significant.

Mould in Queensland rental housing

Queensland’s minimum housing standards require a rental property to be free of vermin, damp and mould, except where the tenant caused the problem. The standards have applied to all Queensland tenancies since 1 September 2024. They sit alongside the general obligation to keep premises fit to live in and in good repair.

Responsibility can depend on the cause. A roof leak, rising damp, a failed shower seal inside a wall or poor drainage points to the building. Condensation from day-to-day living without ventilation is usually treated as the tenant’s responsibility.

A landlord’s failure can support two separate things:

• A tenancy dispute through the Residential Tenancies Authority and, if needed, QCAT, about repairs, rent reduction, damaged belongings or ending the lease.
• A compensation claim for damages, where the failure caused a diagnosed condition. This is a public liability style claim, and it runs through Queensland’s pre-court procedures.

The two run separately and on different timelines. Neither prevents the other.

Mould exposure at work

Mould at work takes several forms: a water-damaged office or school, a contaminated air conditioning system, or a building where a leak was reported and left unrepaired. The same causation questions apply as anywhere else. The evidence needs to show what the exposure was, roughly how much of it there was, and how it caused the diagnosed condition. Incident reports, air monitoring, remediation records and complaints to management are often useful.

A workplace exposure may support a statutory workers’ compensation claim with WorkCover Queensland. That pathway is no-fault, and it is usually the faster one to start. Where the employer’s negligence contributed, a separate common law damages claim may also be available. Our guide to lodging a WorkCover claim in Queensland explains the early steps.

If the condition means you can no longer work, a TPD claim through superannuation may also be worth checking.

Time limits for mould exposure compensation

In Queensland, the general time limit for a damages claim is three years, under the Limitation of Actions Act 1974 (Qld). Queensland’s pre-court procedures also require notice steps to be taken well before that deadline. Where exposure was ongoing over months or years, working out when time began to run can itself be a question.

WorkCover claims generally need to be lodged within six months of the condition being assessed by a doctor. Tenancy disputes have their own time limits too. There is more in our guide to time limits for compensation claims.

What to do now if mould is affecting your health

• Look after your health first. See a doctor, describe the building and your symptoms, and ask that both be recorded.
• Notify in writing. Tell the landlord, property manager, employer or body corporate in writing, and keep copies of everything sent and received.
• Photograph the problem. Take dated photographs before any cleaning or remediation, and keep damaged items where you can.
• Keep a simple timeline. When the problem started, when you complained, what was done and when your symptoms changed.
• Avoid unqualified conclusions. Home test kits and online symptom lists rarely help a claim. Qualified testing and specialist opinion do.

How the firm approaches a mould enquiry

These claims are run for people across Queensland. The first step is an honest look at the evidence, particularly the medical evidence and the paper trail.

Mould claims can vary in value, and the medical evidence they need can be expensive. The firm does not generally pursue claims likely to be worth less than about $10,000, because disbursements can consume most of the benefit. Where that is the likely position, you will be told at the outset, and pointed to the tenancy or workers’ compensation pathway that suits the problem.

Where a claim goes ahead, it is run no win, no fee*, and the firm does not use litigation funders. Legal costs can often be claimed in addition to compensation recovered, and interest is charged only on legal costs that remain unpaid. Disbursements are separate, and they are explained in writing before they are incurred.
