Professor Grant McTainsh, from Queensland's Griffith University, said the combination of prolonged drought and the summer storm season could bring dust storms to Queensland, NSW, Victoria and South Australia.
On Sunday night, an estimated 16,000 tonnes of dust - about 4,000 semi-trailer loads - blew across Brisbane and the Gold Coast.
"It appears red dust from western Queensland that has been in the air since last Thursday was flushed out of the air last night during thunderstorms," Prof McTainsh said.
Professor McTainsh said the drought across eastern Australia had left large areas open to wind erosion which in turn resulted in dust storms.
"This erosion produces dust that engulfs rural towns and reaches as far as Brisbane and the south east," he said.
"Later in the season we can expect dust activity to move further south towards NSW and Victoria."
