In remote West Papua, whale sharks gather year-round around bagan lift-net platforms where fishermen have shared baitfish catches for generations. Encounters feel extraordinary but research shows high scarring from nets and boats, prompting calls for safer platform design and stricter tour codes. Liveaboard season peaks when calmer seas arrive from September through October.

No. Sharks associate with traditional bagan lift-net fisheries that attract baitfish naturally. Fishermen may share small catches, but this differs from dedicated tourist provisioning operations.
Encounters happen year-round around bagan platforms, but liveaboard operators prefer calmer seas from August through October for multi-day West Papua itineraries.
Eight to ten day liveaboard packages typically run 28 to 45 million IDR per person, roughly 1,750 to 2,800 US dollars (2026 prices), including bagan visits and park fees.
Park codes generally prioritize snorkeling near bagans. Confirm rules with your liveaboard operator before diving close to platforms where net scarring remains a research concern.
Most travelers fly to Sorong in West Papua, then board liveaboards for the multi-day crossing into the remote bay. No day-trip infrastructure exists from tourist hubs.
