Arnehm Land: been invited, any good 4WD treks...

We've been invited in June 2002 by a friend who lives there.

Can anyone recommend
- Good 4WD tracks
- Good camping spots (permitted where no permit required ) & permitted with permit.
- Good fishing spots and areas
- Type of fish
- Specially how do get the FISH BAITS and what type of BAITS ( It got to be legal)
( I have a good cast net to catch live baits)

Arnhem land is large. Pint pointing the exact location is tricky...
This is a land where permits are required to travel inside Arnhem land.
We have the permit, but as mention above it is difficult to obtain accurate information.
Anyone with accurate infos (website - fax numbers specially etc.. we'll be realy appreciated)
[ I serahced the web for 8 hours and found little information - only tourist operator wanted me
to spend hudred$$$$ before to know what I am getting in for.....
