Hi George, it look as if something went wrong with this post. The location is mapped as Mt Taylor but described as Coombs Peninsula, and the photos may not be the ones you intended. I cant see any sign of fauna in the main photo, which appears to be of the cut-off drain at Mt Taylor. In the other photos there are burrows, but they look more like fox or even rabbit than wombat. The dung nearby looks to be from kangaroos. However the size of the holes is hard to discern (from my end) and maybe you found wombat dung which I have overlooked.
