These are roo tracks in the mud around a gently overflowing water trough. The marks of their long back legs and toes, flanking those of the paws of their short forearms. A family of roos, a mob of tracks circling the round trough, all quite a way back from its edge.
There are tiny scratch marks on the rim of the trough, where they rested their front claws as they leaned forward to drink. These are just visible on a blown-up version of the picture of this trough on the previous post.
