The road from Port Disgusting to Darwin is flat as a ****carters hat and bloody monotonous,great surface especiallly over the NT border.
Lotsa stops fer a pee and leg stretch.IMHO there is not a bloody thing worth stopping for enroute to Darwin except possibly to see how the other half live in the Todd River.
Dont be tempted to stop after Alice Springs it will probably depress you so much you wont want to come on to Darwin.
You in for a pleasant surprise when you get here lovely modern city... er..that is just waiting for someone to move in.
Make sure yer cars works good BEFORE you leave.The highway is lined with thieves disguised as service stations.
