From Sequence 04 and onward you can upgrade Great Inagua the same way you would upgrade your home in previous Assassin's Creed games. In some cases you will need to make straight purchases in the town to upgrade the island, while other items like the Art Collection is unlocked through Kenway's Fleet or purchased from the General Store.
