I have added the tag landcover=dry_swamp in order to identify them in a 
searchable way.

https://taginfo.geofabrik.de/australia-oceania/australia/tags/landcover=dry_swamp

Some 4,347 now.

99% of them tagged with 'natural=mud'

OSM describes 'mud' as "wet, water saturated fine grained soil without 
significant plant growth." As these areas are dry most of the time and 
have plants.. square pegs in round holes.

Within Australia 'natural=mud' has some 4,550 uses .. deduct 4,330 dry 
swamps with that tag and it leaves 220 mud areas that are not dry swamps...
