All drying appliances should vent externally, in addition to ensuring a window is open during use.


After a shower or bath, properly ventilate the room via dispersing the steam outside of the house and not allowing it to migrate to other rooms. Open a window and close the bathroom door to ensure proper ventilation. If you have an extractor fan, this needs to be switched on during showering/bathing and left on after. Ensure you clean up puddles of water as they can cause more moisture.


When cooking, keep windows open and if you have an internal door to your kitchen, keep that closed. Always ensure your range-hood fan is on.


Purchasing a dehumidifier (capsule box) from Bunnings is inexpensive and an effective way to reduce moisture in a small space like a wardrobe. Alternatively, you can purchase an electric dehumidifier unit which is effective for bigger spaces. Click the link below for more info

If mould is found outside of these boundaries, the strata scheme may be responsible for these repairs and the mould remediation costs. If the cause of the mould is within the lot boundaries, the lot owner may be responsible for repairs and the costs associated with that.
