Dust storms are moving through Brisbane and other parts of south-east Queensland this evening for the second time this week.

Residents in Brisbane say they can taste the dust in the air and it is visible at Robina on the Gold Coast.

Earlier today it caused more health problems in New South Wales.

On Wednesday large parts of both states were choked by thick clouds of red dust, but today's storm is not as bad.

The New South Wales Ambulance Service says there has been an increase in the number of call outs for respiratory problems because of today's dust storm.

Paramedic David Morris says it was a busy morning in Sydney with many people experience breathing problems.

"Thankfully it's not as busy as it was on Wednesday with the amount of dust that has been around but between 7 and 8 o'clock this morning we still had double our jobs for breathing problems compared to yesterday," he said.

The thick haze is clearing in Sydney as it moves north-east, but health authorities say pollution levels are still hazardous.

Senior forecaster Ben Annals says winds in front of the main part of the storm have been kicking up loose dust as it moves closer to the coast.

He says the dust storms in south-east Queensland will not be too severe because it is dark.

"Basically its going to arrive during the evening and it'll be dark anyway so basically I guess people probably won't notice too much while its dark, but it may have an effect on airports and such," he said.

Carmel Meurant runs the Nardoo Station Tourist Retreat at Cunnamulla in outback Queensland.

She says they had just finished cleaning up from Wednesday's storm when the dust returned overnight

"Luckily I've got two days spare to clean-up and then we're booked out again so everything has to be cleaned again so something to look forward to," she said.

Forecaster Jane Golding says two dust storms in less than a week is extremely unusual.

"[It would be] be pretty unusual if we get another one any time soon," she said
