The photos above show the entrance to Luna Park and the the Sydney Opera House during and before the dust storm.
The storm has forced people indoors and stripped thousands of tonnes of valuable farmland topsoil away.
The dust blacked out the town of Broken Hill in the outback on Tuesday, forcing a zinc mine to shut down. It then swept 725 miles east, to shroud Sydney with red dust.
International flights were diverted from Sydney, ferries on Sydney Harbor were suspended and commuter motorists warned to take care on roads as visibility was dramatically reduced. The dust set off smoke alarms in some buildings in Sydney's central business district and brought construction to a halt.
