Have a look at Coomalie Creek - on the eastern side of the Stuart Highway about 5 Km south of the Batchelor turnoff - power, basic amenities and some pretty ordinary water but its only $20 a night. Berry Creek is closer to Darwin but at $27 a night is one of the lower cost CPs and I don't know if they take big rigs. We've just spent 4 weeks up there and trying to find a campsite with vacancies is pretty difficult. Wikicamps provides the best guidance and info about sites and up to date comments and prices.
Anybody know of cheap or freebies campsite in or around Darwin area for a big rigs.
