Pulau Tioman, one of Malaysia's most popular dive islands off the east coast of Peninsular Malaysia, is under scrutiny after two foreign tourists died within less than three weeks in September — and now the country's main diving body wants answers.

The Malaysia Scuba Diving Association (MSDA) has formally called for a comprehensive investigation into both fatalities, with president Aminor Azmi Abdul Latip saying operators found to have breached safety standards should be ordered to stop running trips altogether.

The first death came on 12 September, when Sabiya Shiek, a 65-year-old tourist from India, slipped from a boat shortly after leaving the water following an introductory dive. On 30 September, Mohammed Seyar Musazay, 55, got into difficulty towards the end of a Discover Scuba Diving session off Kampung Salang and could not be saved. Both incidents involved entry-level experiences — the kind of taster dives aimed at beginners with no certification, which typically require close instructor supervision.

MSDA has asked police, the Ministry of Tourism, Arts and Culture and the Tioman Development Authority to carry out what it calls a thorough and impartial review. It wants investigators to check dive centres' operating licences, instructors' professional credentials and whether annual renewals and Emergency First Response certifications are current. It is also pushing for scrutiny of supervision ratios, staffing levels, equipment maintenance, operating procedures and emergency response readiness.

Aminor was blunt about what should happen if problems are found: severe action, including suspending operators from business. He stressed that safety must always come before commercial considerations, and warned that further incidents risk damaging confidence in Malaysia's wider diving industry — a significant concern for a country whose marine tourism relies heavily on destinations like Tioman, Sipadan and the Perhentian Islands. He has also urged operators, dive professionals and training organisations to review their own safety and emergency procedures in the meantime, and to fix any weaknesses promptly.

Why should travellers care? Discover Scuba Diving experiences are often holidaymakers' first taste of the underwater world, and they depend almost entirely on the operator's discipline: low student-to-instructor ratios, well-maintained gear and clear emergency planning. This story is a reminder to ask a few direct questions before booking an intro dive anywhere — how many divers per instructor, when the equipment was last serviced, and whether the centre is affiliated with a recognised training agency such as PADI or SSI. Tioman remains a lovely, affordable dive destination with fringing reefs, turtles and easy access from Singapore and Kuala Lumpur, but this episode shows why choosing a reputable, well-staffed dive centre matters more than grabbing the cheapest deal on the beach.

The investigations are ongoing, and the outcome may bring tighter oversight of how intro dives are run on the island. Until then, anyone planning a dive trip to Tioman would be wise to book with established centres, check current reviews and be honest about their own comfort level in the water.
