Falling-apart abandoned nest in Spear Thistle with one empty eggshell (original position of shell shown in photo 4). About 4m from active Superb Fairywren nest in sighting 4369995. Wrens often in this area.
Again, I'm quite confident this is a Fairywren nest, because the egg patterns are identical to Fairywren eggs, and the general structure of the nest and location low to the ground seems to suit Fairywren well, as opposed to other similar species.
