Is there a secret island in GTA III or it is a myth and how can I get there, if that's true?

you can fly to the bank you see in the beginning sequence if thats what you mean but its not solid ground which means you'll drown/crash the dodo if you try to land

There is also one of small island that you have to visit (using boat) to pick up one of the packages.

Methinks he means Carser City. No, that is a myth.

Isnt there a massive garage complex with all the cars on the game + hidden ones that gets unlocked once you complete 100% ?

I doubt it.

Many mods are avalible for things like that though. Sometimes the people who start these rumours have many mods installed so they forget which things are added by mods and which are in the proper game.

Oh, i didnt know there were mods for GTA i just play it on my console ;)

Yes. In the third island.

I meant on a different island =)

I dont think theres another island, besides the three... :whistle:
