Where was your favourite Australian holiday and what made it so memorable?

we drove from Sydney- S.A, up to the centre, stopped at Coober Pedy, what a fascinating place, then to Uluru, beautiful, then worked our way up to Darwin, stopping Alice Springs, Tenant Creek,Mataranka, Katherine. So many things to see and do. Spent 5 days in Darwin, the nicest, cleanest place I have ever been to, can't wait to go back. Then back down to 3 ways and across to Townsville, and slowly made our way back down to Sydney. The red centre was the most memorable, camel riding and just the sights, gorges, springs etc. This was actually our 1st time out of nsw, my wife & I drove this trip in 6 weeks with an 8 year old child in the car, & we all survived. Cant wait to do it again, but take 6 months, not weeks.
