What kind of island, tropical, artic or something more temperate? would make a difference.
If tropical I would want,
A fishing pole, A knife, A friend to keep me company and help us survive.
If Artic,
A big coat, to stay warm A lighter to start fires to stay warm and melt ice or snow to drink. A friend to keep me company and help us survive, plus share body heat with in the cave at night.
If temperate,
A knife, A hammer, Someone else to help me survive as there is no way I would survive on my own on any of these islands.
An endless supply of food and beverages that will never go bad or spoil.
A woman who wouldn't mind spending the rest of her life with me.
A magic genie lamp with a genie inside that I would use to break OP's rules and escape the island once and for all. You can't stop me!
If you wanted to be all "realistic" and all, I'd bring one camping backpack full of useful stuff inside it (like knife, rope, 500 page notebook, pencils, pens, flashlight, solar charger, etc) as the first thing, as well as a satellite phone, and that woman I mentioned earlier. Three things.
1. A Fully loaded with fuel, propane gas, foods, drinks etc... Heaviest Lifting Helicopter in the world (Mi-26) (Helicopter is not for escape, just a one way trip so I can bring absolutely everything that I would ever need).
2. The Most Luxuries RV money can ever buy, basically a multi million dollar house on wheels
1. a large sharp knife, to cut branches and leaves for shelter and for making spears to hunt for animals and fish 2. a box of matches, to make fire for warmth and for cooking 3. a medical kit for dealing with the inevitable wounds I will get
Daily food and drink delivery A sturdy house, furnitured A charged phone with wifi that the delivery food guys take with them if dead just to recharge and give it back to me the next day
Map of what? It's a deserted island and I'm sure has not been surveyed either. A big box of tampons would have been a good idea though. You never know when you will be rescued. I'm surprised no one asked for a hot guy. ha ha
My bugout bag bc you said items which is 1 items with many different contents in it. my dog and a woman that knows how survive and can't get pregnant bc a island isn't for little ones running around
