We done the same trip last August and loved it. The places we loved the most where uluru, devils marbles, kings canyon, Richmond/hughendon, airlie beach (but on heaps of bushmans withe midgies) 1770, southwest rocks. These are the places that stood out but everyday was a great adventure. The east coast was awesome as there was great free water parks for the kids at Townsville and Harvey bay and just so much to do. One thing never become complacent with leaving things out or stuff unlocked. We took two cameras and one was stolen at suffers paradise and we lost about 100 photos and had our kids catching there first barra etc etc so was devastated for a while. We had so much fun and can't wait to do a similar trip. Below is a list we made on the iPad to do before we headed off if it helps. Also we used the free camps Australia volume 6 heaps.
