We were staying in Longreach in April 2015 when I saw my first brolga. There were a half a doxzen or so just roaming around the caravan park and some more in the streets. I saw them again later in Sapphire in the Central Queensland Gemfields. There is a mgnificence about them.
Yes yes yes I have seen brolgas in the wild. Sometimes along pumicestone rd going to toorbul there will be a pear of brolgas and if you are really lucky you will see two jabiru with them. It is not close up but you have a clear view. Take binoculars and a good zoom lense camera.
