Beer, 4x4 recovery gear, shovel, fishing rod holders (pvc pipe), good camp chair, head lamp, 12 volt light, esky, rod holders for travelling, sharp knives, insect repellant, toilet paper, esky or fridge, bedding and a good tent if camping 

I would aim to go around end of April early May for the weather as it should be pretty pleasant then and good winds for camping. And being that's it's your 50th more beer. 

 Heh ta mate, sadly im whats called on trawlers "an embarresment to fisherman"

Eg i dont drink lol.

But rest of the stuff cheers man noted an added to list.

Anyone can recomend a good 4x4company ? Most of ones ive looked at so far are campers.

 Ok Tassy have you worked out if you are staying in a cabin or hiring a camper for the time?

You mentioned earlier that going to the ocean side, dirk hartog, the cut might be on the cards. If you are staying up near Denham or monkey mia then that is a long drive. Plenty of cabins available up that way if you go out of school holidays. (recomended)

If you hire a camper then you can change spots pretty easily. Try the ocean side, bay sides etc. Not locked into one spot and can get good fishing no mater where the wind is coming from. Wind up there can wreck a good holiday.

Last time i went up there (earlier this year) i stayed at Nanga Bay. Check out my post with the search function. It's kind of centeral to going to Monkey Mia or around to the ocean side. There are cabins available or a caravan park to camp in. There was not a huge amount of people there as we went just after the school holidays in April/may. The facilities are getting a bit run down now as the park is owned by an old chineese lady who was a bit schizafrenic. nice one day and a complete bitch the next. Fuel is also available there.

If you want to get a camper then i recomend Crickey Camper hire in ozzy park. They do a 4x4/camper package that is pretty competative and the 4x4's are well set up. I recomend you go for a fridge also that they hire pretty cheap.

If you are going for a beach/rock rod then i recommend a 10-11ft Ugly Stik. Tough enough to haul a snapper up the rocks and will give you an average cast from the beach. Cheap enough also. Pair that with an 8000 size spinning reel with 30-40lb braid and you cant go wrong.

The drive up there can be done in 1 day but it is a long day. The roads are in good nick and wide enough not to worry about the roadtrains. The roo's can be pretty thick in the mornings/arvo's especially if there has not been much rain during the wet. They will be chasing the verge grass if it has been dry. Goats and sheep everywhere but generally not on the road until night time.

If you plan on getting right off the beaten track then a personal EPERB is pretty important. 1 rule is dont leave your vehicle so with an EPERB you have peace of mind knowing someone is deffinatley coming to get you if you are in trouble. Double the insect repelant count. Thay have been known to get thick.  If you are camping then make up some quick and easy meals and freeze them before hand. Spag bol, curries, stews and some sauces for cooking fish in. Nothing worse than getting back to camp and having to cook for 2 hours. If you have an engel fridge set it to freeze and just have a small esky for your cold foods. Make the ice for the esky and freeze down the fish you are catching.

Hope that helps a bit.

Something you may want to consider while you are there is to do a day charter. I believe Mac Attack is still doing charters, not sure about anyone else. Guarantee you will have a ball.

I will be doing that. I wanna go out an try for deep stuff. Dont have back for game fish these days, so a nice snapper will keep me happy :p
