There were a few about, but I only got good photos of one. Note the context: a dense messy thicket composed almost entirely of weeds of every description. I have found, in the course of the past eight years that I have been observing wildlife in suburban Brisbane, that it is places like this that are most likely to contain fairywrens and other little bush birds. If you can walk straight through it without barking your shins or bumping your head; if you can see the ground between the plants; it probably isn't wren territory, even if it is composed of native plants and only native plants. Fairy-wrens seem to be perfectly content to inhabit - and thrive within - a mass of lantana or leucaena well mixed with tall weed grasses.
Female. She seemed to be on her own; I couldn't see her mate anywhere.
There were others about at the time - this wasn't the only one - but this was the only one I saw AND could get a photo of!
