Bulldust

Bulldust or bull dust is a fine, soft and powdery red aeolian dust that is common across Australia, especially in the Outback and desert. It is a type of fugitive dust that, when disturbed, can have dangerous effects. It is common on remote roads, especially in the far north of Australia where the wet and dry season can cause the roads to either be boggy or very dry. The term originated in the 1920s.
