The debate between Thailand's Andaman GT fishing and the Pacific's blue-chip destinations comes up in every serious GT fishing conversation. Hawaii, French Polynesia, and the Cook Islands are the Pacific's prestige addresses — remote atolls, enormous fish, and the kind of wilderness that makes an Instagram caption write itself. Thailand offers Similan and Surin liveaboards with professional English-speaking guides, diverse non-fishing tourism, and total trip costs that come in at 30–50% of comparable Pacific itineraries.
The question is not which fishery is physically larger. It is which one makes sense for the angler you are, with the budget you have, and the trip experience you want.
The Thai Andaman: What You Actually Get
The Similan and Surin archipelagos form a national marine park in the northern Andaman Sea. Protected status has allowed GT populations to recover and stabilise at impressive levels. A five-night liveaboard from Tap Lamu to the Similans and Surins delivers consistent encounters with GT in the 8–30 kg range, with fish over 20 kg genuinely common during November through February.
The Andaman's GT are not consolation fish. They are large, aggressive, and perfectly capable of destroying tackle that is not up to specification.
The liveaboard infrastructure is mature and professional. The principal operators have run these trips for decades, their skippers know the structure at each island group, and the guides understand GT behaviour at both the Similan pinnacles and the Surin outer bommies. English is spoken, safety protocols are current, and the boats are maintained to a standard that matches operators in more expensive destinations.
Additional species on the Andaman circuit add value that the Pacific's pure GT destinations cannot match: dogtooth tuna in the canyon systems between island groups, wahoo on the open water crossings, and the completely different experience of GT on the limestone walls in Phang Nga Bay before or after the liveaboard.

The Pacific: The Trophy Argument
Hawaii, French Polynesia, and the Cook Islands represent the upper end of GT fishing globally — not because the Thai fish are small, but because the Pacific's remote atoll systems hold GT populations that have experienced even less pressure and therefore grow to larger average sizes.
Hawaii
Hawaii's GT fishing concentrates on the remote outer islands and atolls — Midway, the Kure Atoll, and the Northwestern Hawaiian Islands — rather than the main tourist islands. These are not accessible to casual anglers and require specific charter operations or government permits. The fishing is exceptional when access is granted; fish over 35 kg are realistic in these systems. Cost is high: a week's access typically runs USD $1,200 per day or more when you account for the permit, charter, and logistics.
The main Hawaiian islands offer more accessible but less productive GT fishing — reasonable day-charter options exist around the Big Island and Maui, targeting smaller resident GT populations. These are more affordable but not in the same class as the Andaman liveaboard experience.
French Polynesia
Fakarava, Rangiroa, and several other Tuamotu atolls offer spectacular GT fishing in the famous passes — narrow channels between atoll lagoon and open ocean where current accelerates and concentrates baitfish. GT stack in these passes in numbers that can produce extraordinary days on the right tide. The visual environment — crystal-clear passes with 30-metre visibility, shark packs, and enormous schools of baitfish — is extraordinary.
Cost is substantial: French Polynesia is an expensive destination by any measure, and dedicated GT fishing lodges and charters add significantly to the base cost of reaching Tahiti from most departure points. Operators are variable in quality; research is essential.
French Polynesia pass fishing is season-dependent — the best GT action in the Tuamotu passes runs April through November, which does not overlap with the Andaman season. An angler who wants to fish both can do so without conflict, rotating between destinations seasonally.
Cook Islands
The Cooks, particularly Aitutaki and the outer group islands, offer remote GT fishing with a reputation for large average fish sizes. Access is limited — very few dedicated GT fishing operations exist — and the logistics of reaching the outer islands from Rarotonga add cost and uncertainty. The reward is fishing that receives minimal pressure and holds exceptional specimens.
Cost: Where Thailand Wins Decisively
The cost comparison is stark. A week's GT fishing in Thailand — including a five-night Andaman liveaboard, accommodation in Khao Lak, and day-charter options — runs USD $2,500–3,500 per person excluding international flights. A comparable week in French Polynesia or the Cook Islands, accounting for destination cost, charter fees, and internal flights, runs USD $6,000–10,000 per person minimum. Hawaii's remote atoll fishing is comparable in cost to French Polynesia when all logistics are included.
For an angler who wants to fish for GT every year, the cost differential is the difference between an annual trip and a biennial one. Many serious GT anglers now fish Thailand annually and save the Pacific destinations for milestone trips.
At 30–50 cents on the dollar versus the Pacific, Thailand's Andaman GT fishing is not a compromise — it is an entirely rational choice.
Fish Quality: Closing the Gap
The Pacific's largest GT destinations hold fish that, on average, run slightly larger than the Andaman. This is a real difference and worth acknowledging honestly. A 40 kg GT on a French Polynesia atoll is not a fantasy — fish of that size are caught with meaningful frequency at the right locations. In the Andaman, a 30 kg fish is exceptional rather than routine.
For anglers for whom the absolute size ceiling matters — who want to say they have caught the largest GT possible — the Pacific's remote atolls hold a genuine edge.
For anglers who want consistent encounters with large, powerful fish in a professional fishing environment, the difference narrows dramatically. A 25 kg GT on PE6 tackle in the Similan Islands is an extraordinary fish that will test every component of your setup. The technique required is identical. The physical demand is nearly identical. The memory is comparable.
Verdict: Thailand Wins for Most Anglers
The Andaman is the correct choice for the overwhelming majority of GT-focused anglers. The cost savings are real and substantial, the operator infrastructure is mature, the species diversity adds value the Pacific can't match, and the fish are genuinely large. The Pacific's premium destinations justify the premium cost for anglers on milestone trips — the 40 kg mark, the bucket-list atoll, the remote wilderness experience that no amount of money can replicate in a national marine park.
If your primary goal is maximum encounters with maximum-size GT at minimum cost, the Andaman wins. If your primary goal is the largest possible fish in the most remote possible setting, save the money and fly to the Cooks.
Most anglers should do both, sequenced to the seasons: Andaman in November–February, Pacific in May–September. The two destinations complement rather than replace each other, and understanding both is what separates a GT angler from someone who has merely caught a GT.
