A 39-year-old Malaysian diver, Siti Nuraini Binti Rusidi, died on 16 September after getting into trouble during a dive at Crystal Bay, the famous — and famously challenging — dive site off Nusa Penida in Bali, Indonesia. She had been diving with Dive Concepts Lembongan, based in Jungutbatu Village on neighbouring Nusa Lembongan.
The day started normally. The group's first dive, at Manta Bay on Nusa Penida's southern coast around 8 am, passed without problems. According to Bali Police, the dive guide had noticed Siti coughing beforehand and checked she was fit to dive; she said she was. By 11 am the boat had moved to Crystal Bay, and the guide again asked whether she wanted to sit the next dive out. She chose to go in.
She became separated from her group in a strong current — something Crystal Bay is well known for. She was later found with a different dive team, where she signalled she was out of air and panicked, removing her regulator. That guide passed her his alternate air source and brought her up to the boat, where foam was seen coming from her nose and mouth. She was still responsive, but by the time the boat reached Lembongan she was unresponsive. Staff at Nusa Medika Clinic pronounced her dead on arrival. Her body was taken to Bali Mandara Hospital in Denpasar, and police — who have interviewed the guide, the boat captain and other group members — are still investigating the cause.
Crystal Bay draws divers from around the world for one main reason: the chance to see giant sunfish (Mola alexandrini), which gather in cooler waters around the Nusa Islands. But the same conditions that attract the molas make the site risky. Powerful currents sweep through the bay, and at certain tide states dangerous downcurrents can pull divers downwards quickly. It's a site where experience levels genuinely matter, and where conditions can shift between dives on the same day.
For anyone planning a dive trip to Bali's Nusa Islands, the takeaways are sobering but practical. Be honest with yourself and your guide about how you're feeling — fatigue, illness or a lingering cough are good reasons to skip a dive, and a good operator will never pressure you into the water. Check that your guide briefs you on current procedures and carries surface markers, and ask about tide timing before committing to the headline sites. And if you're newly certified, consider easing in on calmer sites elsewhere in Bali before taking on Nusa Penida's mola runs. The islands — Penida, Lembongan and Ceningan — remain superb diving, but they reward preparation and humility in the water.
