Getting There & Away
The Castlereagh Hwy (Rte 55, part of the 'Great Inland Way' linking Sydney and Cairns) forks off the Oxley Hwy at Gilgandra then runs to the Queensland border through Coonamble, Walgett and the rugged opal country of Lightning Ridge.
The Newell Hwy (Rte 39), the through-route from Victoria, passes through stargazing Coonabarabran and the burgeoning Aboriginal art hub of Moree, before hitting the border at Goondiwindi.
NSW TrainLink operates daily XPT trains to Moree, the end of the line, connecting to buses to towns further afield. Beyond Moree, public transport is scarce to non-existent.
Having your own wheels will help with explorations of this far-flung corner of the state.
