My wife and I are booked to go to Darwin in Sept. We want to rent a
campervan, tour the area and then drive to Cairns. I know from two
previous rentals in Oz that the companies don't allow their vans to be
driven on unsealed roads. My questions is: Will I be able to able to
explore the National parks in a 2WD or will I have to rent a 4WD?

also any suggestions on companies to rent from, places to go, hotels in
Darwin would be welcome.
Thanks in advance.
