What would you take if you were going camping in the wilderness for weeks at a time without access to civilization?
What level are you and how much wealth? Bags of Holding and Handy Haversacks are going to be well worth it if you can afford them. Fill them up with mundane items including tools and camping gear.
Why are you buying supplies for being shipwrecked on an island? Did you book a passage on a ship traveling to a shipwreck? Are you planning on causing the shipwreck yourself?
Slings - you'll never run out of ammo.
Why would i want to use a sling?
Cost nothing, weighs nothing, and the ammo cost nothing and weights nothing. Everyone but the druid has proficiency, so there is little reason not to get one.
Net and light crossbow. good for fishing and hunting.
And as far as slings go, I think the only time you incur a STR penalty is using a bow.

The sling may cost and weigh nothing, but the ammo does. 1 silver piece for 10 bullets, which weigh 5 pounds total.
And Strength penalties do apply with slings.
Sling: A sling is little more than a leather cup attached to a pair of strings. Your Strength modifier applies to damage rolls when you use a sling, just as it does for thrown weapons. You can fire, but not load, a sling with one hand. Loading a sling is a move action that requires two hands and provokes attacks of opportunity.
So with just a 7 strength, thats only 1d4-2 damage. 1d4-3 if he runs out of bullets and must start using regular stones.
How can a wizard fish/hunt with nothing in survival? It doesn't really fit the character theme either (unless you are specifically playing a wizard who grew up doing that stuff).Net and light crossbow. good for fishing and hunting.

Survival isn't a trained skill. Anyone can attempt it even with 0 ranks. By Taking 10, anyone (as long as they don't have a Wisdom penalty)can get along in the wild and provide enough food and water for themselves every day.
And as Track is no longer a feat in Pathfinder, everyone can track with Survival as well.
A Halfling with the Well-Prepared feat might prove useful.
Spell pouches. Without them, you're sunk.
A boat?
A fishing rod, a gold medal at the end of its line, and Michael Phelps.
Wait, we're not playing that game, are we?
...I'd bring basic gear. Pack, bedroll, food, waterskin. Maybe some rope, definitely flint and steel if not tindertwigs.
If it fits the character and you can afford it, the False Focus feat combined with a tattooed holy symbol can allow you to basically forgo material components up to 100 gp, and you don't even have to worry about losing a holy symbol.
I would make a regular character, and treat any problems that arise from being shipwrecked as a challenge to be overcome. Though I would strive to avoid character options that would be overly gear-dependent, as being completely useless wouldn't be particularly fun :)
