I will play
Knife wise, where it is tempting to tag my NMSFNO as the knife I would take I would strongly consider something smaller, maybe my BATAC, Fehrman last chance, RAT RC5 or even the new SARLE, those would work better for bush craft and are still large enough for heavy use and they are lighter to carry imo
a good bushcraft/survival book
since I am a beer drinker i would opt for grain alcohol, it would have medicinal purposes and fuel like mentioned before plus I am sure there would be some berries/coconuts or some form of tropical fruit I could use to sweeten it up to drink.
