In general, unless there is major flooding which will be reported in the media, sealed roads remain open all year round.
Traffic is very light except around major towns.
A typical Road Train on the move, this one entering Mount Isa in North West Queensland Lesser roads may be a single lane sealed section with gravel shoulders. Please refer to the travel articles on 'The Northern Territory' 'Outback Queensland' etc. For overseas visitors, remember that we drive on the LEFT hand side of the road.
