I was thinking of spending my mid-semester break on the road between Darwin and Adelaide and one of the spots I definitely would like to see is kakadu national park and/or lichfield NP. I'm not renting a car to travel but I have a bus pass. Therefore, my question is the following one: Kakadu national park being a pretty huge park, I've been wondering whether there would be some shuttles (not an organized tour) that can drive you around the park, like a normal bus with several stops to the main attraction? And same question for Lichfield :)
Thanks for your tips!
