There is no published island-unlock list. The rod sellers reveal the order, because each island's Cash rods sit in a higher band than the last. Battlefield Isle and Mistpeak Isle have no rod seller.

Travel
Talk to the Spawn Boat NPC to sail. After you arrive, use Set Spawn so a disconnect does not send you back to Beginning Isle. Both NPCs stand on the islands.
Bamboo Isle, Frost Isle, and Amber Isle are also the three Spirit islands. The hourly Spirit is a separate 50M Cash interaction, not a weather event.
What each stop is for
Beginning Isle holds Nanjiang, Sage Yijiu's shop, and the Ticket quests. Bamboo Isle holds Giang Lao's first quest, Shadowless Taji Strike. Fallout Isle holds Enzo at Level 1000. Frost Isle holds Ha Dieu De and Sever The Gate v3, plus the Cryo Gravity quest. Coconut Isle holds Bac Minh's orb quest and the Soul Thorn quest. Battlefield Isle holds the five-quest Sage Yijiu chain. Mistpeak Isle is the Mountain Fish and its 5% Mountain Flip drop.
