“Dirty” Rain. 08 Nov 1929. “Australia must be blowing away at an appreciable rate.” Another “Unprecedented Event.” that wasn’t. I can’t fathom how not a single journalist thought to go to Trove and type in “dirty rain” Maybe they’re scared of all the results they’d find. This is just the first two, and they’re not even in summer.

“Dirty” Rain.
A resident at Christmas Creek writes: I have read of dirty water descending in the form of rain and may have ridiculed the idea, but although residing on Christmas Creek for many years I had never had such an experience until last Monday morning, when I found the garden foliage
splashed with water and a brick-red dust.
During the previous night we had several light sprinkles of rain, at various intervals as if a shower was commencing, and then would stop, and although I had not noted the fact there must have been some of this red dust driven along probably by the west wind, and as the rain drop descended they collected and brought down the dust mingled with rain water.

Dirty Rain.
A slight thunderstorm on Saturday night brought down the heaviest deposit of dust ever known in Circular Head.
There were heavy dust storms on the mainland at the time. As it is only when a shower falls during a dust storm that we see it and as what falls on Tasmania must be very small compared with what falls in to the sea.
Australia must be blowing away at an appreciable rate.
