Tanya Fulton runs a bathing facility in Tottenham, west of Sydney, which had to close due to the sandstorm.
"I couldn't even see the bottom of the big pool and in the toddler pool it was just mud," Tanya Fulton told Reuters news agency.
On Monday, the sandstorms are expected to reach more densely populated areas near Sydney. At the same time, a hail storm has pulled over the capital Canberra. Pictures show how hail big as golf balls destroy cars and fill a cricket pitch.
Since September 2019, Australia has been hit hard by extensive fires and a total of 29 people have died. In recent days, many fire-stricken areas have received much-needed rainfall, which has reduced the number of fires. But it still burns in several places in the states of New South Wales and Victoria. Several are still out of control.
