Sunscreen and a hat
Luggage and bags: Travel light. You will have to abide by domestic flight weight restrictions on your bags from the mainland to the island. You can usually take your dive gear plus one other small bag within the allowance.
Clothing/Shoes/Weather Gear: Noronha is a casual place. Shorts, t-shirts and flip flops or reef sandals are the norm, even in the evening. Less is more in terms of Brazilian standards.
A hat and sunglasses are indispensible.
Toiletries and Medical Supplies: Sunscreen, bug bite relief, sunscreen, sunburn relief, allergy meds, SPF lip balm, dramamine, sunblock, and hangover relief (for those post "caipirinha" mornings).
Photo Equipment: Goes without saying. Underwater photographers are guaranteed to get shots of turtles, rays, morays, giant grouper, and sometimes even dolphins.
Camping/Beach/Outdoor Gear: Anything you need to enjoy playing in the water. Take a daypack to carry fins & mask, towels, water, etc for forays to the island's beaches.
Miscellaneous: You may want to pack a flashlight to walk around at night on poorly-lighted streets and roads.
