As part of my planned trip around Australia I want to backpack around all the best bits

Lots of wildlife and great scenery, great sunrises and sunsets, lots of diversity, trying to see things I've never seen before. So where should I go and what should I see. I'm open to all suggestions and will have a go at most trips, adventure sports, sleeping rough is all OK if that's what it takes. Hopefully you can fill me with lots of ideas to help plan the trip.
Thanks
