Surviving on the island is not a long term solution. You want to get out into the shipping lanes so you can be rescued.
Inflatable raft: To get away from the island to the shipping lanes. Assuming the island has some palm trees, break off branches to use as shade on the raft.
Flare gun: Once you get away and (hopefully) into some shipping lanes, you can use this to attract their attention.
Water purifier: To get some all important water, without it you won't last long. Obviously you can't purify salt water, so you will have to dig some holes on the island and hope you can find fresh water, and then purify that.
Knife: Break open coconuts for the flesh and milk, and they can also be used to put purified water in for later. Dig some clams out of the sand and open them up for food, catch a crab or 2.
I was thinking along the lines of this too! I would go for:
Raft - Get off the Island
Flare gun - Signal passing ships
Water purifier - Desalinate the seawater
Fishing Rod - For catching fish
