Sydney Dust Storm, originally uploaded by tomhide.

Found this awesome photo and entry on Flickr about the dust storms in Australia. This dust storm looks hectic, I can’t believe people braved it to go for a walk, let alone go take photos. I would hate to think what all that dust must do to the camera equipment.

I wonder if it was a fine dust? or perhaps more sandy dust? Sandy dust could do some serious damage if its moving at high speed, it would basically sand blast everything in its path.
