Thanks every one for your replies.
We have pegged in 5 weeks in August heading up to the Bungle Bungles, and then up to Keep River National park in the NT. On our way back I have decided to go along the Duncan Hwy taking our time to have good look around, Then back thru to Halls Creek with a stop over at Wolfe Creek Crater.
On our way home, I'm going to camp at Red Bluff (Quobba Station) for few days before getting back to the big smoke!
Both my wife and I are really hanging out for this...30 days of Swagging in this big state of ours WA and the NT!
