Toxic black mould has been found behind picture frames and underneath mattresses following the nation’s dampest season on record.
One woman revealed online that she was sleeping with mould above her head following intense headaches and sinus infections.
"Unknowingly, every night we've been sleeping with this mould above our heads – wondering why we have headaches, sinus issues and more," she wrote.
A photo the woman posted revealed black mould was thriving behind her bedhead.
Following the discovery, users flocked to comment how the deadly toxin was "everywhere" at the moment.
Mattresses, bases and wooden frames are hotbeds for mould, with some residents saying they only discovered the infestation after they upgraded their bed.
"We upgraded our bed and turns out the bottom of the mattress was all mouldy!" one user said.
The fungi thrives in damp or water-damaged environments and can cause serious health issues if inhaled.
Symptoms of mould exposure include increased risk of asthma, allergies, respiratory infections and coughing.
Australian residents are urged to stop mould in its tracks by using a dehumidifier, opening windows and doors when the weather permits and checking leaky roofs and walls for the toxin.
Stores across Brisbane sold out of mould killer last week as flood-ravaged homeowners attempted to detoxify their homes.
One man even revealed the bare supermarket and hardware shop shelves in a social media post, with another user commenting, "In this day and age you have to be one step ahead of the panic buyers."
A Brisbane Bunnings spokesperson told NCA NewsWire that the store had been running low on mould killer concentrate but still had plenty of pre-mixed options.
