Basically what facilities are there and what it's like and if the main road from Darwin is sealed etc etc.
Yes main road from Darwin is sealed - wet season it gets flooded every now and again but it mostly a pretty good road. About hours to Darwin
Facilities... well they have a primary school (not sure about high school), pre school and I think a childcare centre that is run by the council. There is also a service station a medical clinic, sports oval and I think they have a pool. There is an airport as well.

Weather and all that. Anything!
Dry season is April - September... cooler nights, hot days not alot of humidity - great time to go camping and most of the swimming holes are open - esp in Kakadu (like Gunlom falls)
Wet season - October - March hot, humid, stormy - It's not really that bad, most people get relief from the heat with air cons lots of swimming (but remember Croc's are everywhere - if it's not a swimming pool don't swim in it in the wet season!!)
My DP and I might be going next week for a site visit so I can check it out myself lol.
Cool it is a great time of year to visit the top end.
