A couple of weekends ago I did the Conodale Range Great Walk in SE QLD. You can read about it here for a full trip report.
It was the first great walk I've done in Queensland, and although a pretty rough time of year to do it, there was some cool stuff to see along the way (waterfalls, etc).
Lots and lots of leeches though! I would have counted 50 plus around my ankles at one stage and am still dealing with the itchiness from it! A few good pics on the blog.
Cheers
