I thought it would be easier to go Pacific Hwy to Hexham New England To Singleton Golden Hway to Dubbo and so on.

I would jump on the Oxley Highway turn right at Nevertire and then follow the Mitchell Highway to Nyngan. Turn left onto the Barrier Highway all the way to Adelaide.

There is lots of opportunity for free camps between Nyngan and Cobar. Just keep an eye on which side the rail line is on, the road crosses the railway about halfway, and pull into the bush on the opposite side. There is a large open area on the left just after you cross the rail line but many other places hold promise.

I can recommend the CV Park in Cobar just keep away from the Truck Stop side.

You should be able to get from Cobar to Adelaide in about 10 hours. Grab a nice lunch at the Mulga Inn in Broken Hill and good cakes in Burra for afternoon tea.

A few years ago we travelled from Broken Hill to Ballina in one day basically following the above route. Once you get to Walcha it is very flat and there is virtually no traffic until you get to Adelaide outskirts.

Fastest route is via Sydney, then Hume Highway, turn off to Wagga, Balranald, Ouyen, Pinnaroo, Adelaide. Not really the scenic route but heaps of freeways.

For free camps, look at State Forests - often have free camping if you're self sufficient.Here is a list of NSW state forests that allow free camping.
