Is Mould Dangerous? Health Risks in Brisbane Homes

Mould is more than an eyesore — it can pose real health risks, especially in Brisbane's humid subtropical climate where mould thrives year-round.

How Mould Affects Your Health

Mould produces tiny spores that become airborne and are easily inhaled. When mould grows indoors, these spores accumulate and can trigger a range of health problems, particularly for vulnerable individuals.

🫁

Respiratory Issues

Coughing, wheezing, shortness of breath, and aggravated asthma symptoms.

🤧

Allergic Reactions

Sneezing, runny nose, itchy eyes, and skin rashes from mould spore exposure.

🛡️

Immune Suppression

Long-term exposure may weaken immune response, especially in children and elderly.

🧠

Neurological Effects

Some toxic moulds produce mycotoxins linked to headaches, fatigue, and brain fog.

Who Is Most at Risk?

While anyone can be affected by mould exposure, certain groups face higher risks:

  • Children and infants
  • Elderly individuals
  • People with asthma or respiratory conditions
  • Those with compromised immune systems
  • Pregnant women

When Should You Be Concerned?

According to QLD Health guidelines, you should take action if you can see or smell mould in your home. Visible mould growth larger than a 10-cent piece warrants professional assessment, especially if occupants are experiencing unexplained health symptoms.

Important: Get Professional Help

If you suspect mould in your Brisbane home, don't attempt to remove large areas yourself. Disturbing mould can release massive quantities of spores. A professional mould inspection identifies the full extent of the problem and the safest removal approach.

Brisbane's Climate and Mould Risk

Brisbane's average humidity sits above 60% for most of the year, with summer months regularly exceeding 75%. This creates perfect conditions for mould growth, particularly during the wet season from November to March. Older homes, homes affected by flooding, and properties with poor ventilation are especially vulnerable.

Frequently Asked Questions

Mould exposure is a recognised trigger for asthma symptoms and can worsen existing asthma. According to health guidelines, inhaling mould spores can cause airway inflammation, leading to coughing, wheezing, chest tightness, and shortness of breath in people with asthma. Research also suggests that early and prolonged exposure to mould in damp indoor environments may contribute to the development of asthma, particularly in children. If asthma symptoms are worse at home and improve elsewhere, a mould inspection is recommended.
The term “black mould” typically refers to Stachybotrys chartarum, which is known for producing mycotoxins. However, not all dark-coloured mould is Stachybotrys, and not all Stachybotrys produces mycotoxins in every environment. Health authorities generally advise that all significant mould growth should be addressed regardless of colour, as any mould can cause health effects in sensitive individuals. Visual identification is unreliable for determining mould species — laboratory testing is needed for accurate identification.
Prolonged exposure to mould can contribute to health effects, particularly for sensitive individuals. According to Queensland Health, these may include respiratory symptoms (coughing, wheezing, nasal congestion), allergic reactions (sneezing, runny nose, itchy eyes), skin irritation, and aggravation of existing asthma. People most at risk include those with respiratory conditions, allergies, compromised immune systems, the elderly, and young children. If you’re experiencing persistent symptoms that improve when you leave the home, mould exposure should be investigated.
