The weather has been a lot wetter than expected lately, and with increased moisture in the air comes an increased risk of mould.
The humidity doesn't look like going anywhere soon, especially in the country's south east, with higher than average rainfall forecast to continue through February and March.
So how do we reduce dampness and the potential for the development of mould that is unsightly and hazardous to our health?
Ensure your home is well ventilated
"Keeping air flowing through your home will help prevent humidity and minimise moisture and mould growing," Mr Barnes said.
If the weather is mild and dry outside, opening up some windows and doors can provide some much needed airflow.
Line dry your clothes
Mr Barnes said drying clothes indoors adds to the humidity in the air, while using a clothes dryer also contributes to electrical costs.
"Line drying your clothes will significantly reduce moisture build-up in your home.
"Take the opportunity on a sunny day to hang your clothes outside," he said.
If you do have to use a dryer, buying a condenser dryer can make a big difference. Vented clothes dryers pump humid air back into the room, whereas condenser dryers condense moisture and collect it in a reservoir. Unfortunately, these dryers are more expensive. If buying one isn't an option, you may be able to fit your dryer with a venting/ ducting kit to redirect humid air outside.
Keep on top of your cleaning
Regularly dusting and vacuuming can also help you keep on top of mould, which needs organic matter to feed on, Mr Barnes said.
If left untended, dead skin cells, dust or pet hair can help mould thrive.
Minimise moisture entering the home
The more moisture that gets into the home, the higher the chances of mould.
Checking for and repairing broken tiles and roof leaks, clearing out gutters and downpipes to prevent overflow, and assessing the state of windows and external doors can also be helpful.
Installing weather seals might be a good idea, if needed.
Install exhaust fans
Installing an exhaust fan in the bathroom will help minimise humidity in the room.
An exhaust fan in your laundry may also be a good idea, if you are using a vented dryer.
Use appliances that help prevent and manage damp and mould
Having a dehumidifier in the home can be helpful, as it will remove moisture from the air. Refrigerant dehumidifiers are best for hot, humid conditions, while desiccant dehumidifiers are more suitable for cold, damp conditions.
Air conditioners can also help - not only do they cool the air, they dry it at the same time. But don't set your air conditioner too cold when it's very hot outside, this can cause condensation to form. Mr Barnes said many air conditioners have dehumidify or dry modes, so check your unit doesn't have one before buying a dehumidifier.
Ceiling and pedestal fans can also be handy, and are very inexpensive to run. Ceiling fans can help circulate air through the home, while pedestal fans are good for targeting specific areas that need ventilation.
