Imagine a tropical paradise, once a hidden gem, now teetering on the edge of overexposure. This is the reality facing Mersing, a coastal district in Johor, Malaysia, where booming tourism is threatening the very beauty that attracts visitors. But here's where it gets controversial: can Mersing sustain its allure without sacrificing its fragile ecosystem?
A thrilling 20-minute speedboat ride from the Mersing River mouth transports visitors past a string of tiny islands to an uninhabited, hilly isle. A steep climb rewards adventurers with a breathtaking panorama of islands, sandbanks, and coral reefs shimmering in shades of blue. "It’s hard to believe this is Malaysia!" exclaimed Shamiel Saiful Baharin, a cafe manager, upon reaching the peak of Pulau Seri Buat. He was part of a group from Selangor, who paid RM180 (S$57) each for a weekend retreat filled with snorkeling and island-hopping.
These day-trippers are fueling a tourism boom that’s transforming Mersing. Once merely a gateway to Tioman Island, Mersing is now a destination in itself, boasting 97 islands and rocky islets. Visitors either flock for day trips or stay in mainland hotels and chalets. In 2023, local media reported 700,000 visitors, and by August 2025, over 360,000 tourists had already arrived that year. Johor aims for two million annual visitors by 2030.
But this success comes at a cost. Conservationists warn that the coral reefs, a major draw for tourists, are showing signs of distress. Mersing gained prominence post-Covid-19 lockdown, thanks to government tax breaks and viral videos showcasing its crystal-clear waters and coral gardens, earning it the nickname "Malaysia’s Maldives." While corals showed recovery during the pandemic, Reef Check Malaysia reports that this progress has been reversed in just two to three years. Their 2024 survey reveals coral cover at a barely healthy 50%, down from 60% post-pandemic.
"Most of it can be attributed to the bleaching event in 2024, but some of it reflects broader issues like tourism pressures, coastal development, and pollution," explains Julian Hyde, CEO of Reef Check Malaysia. In September 2025, the Mersing District Office closed six islands for marine rehabilitation, followed by a Facebook post from Johor’s Sultan Ibrahim urging protection of marine biodiversity, accompanied by photos of boats crowding the reefs.
The closed islands, including popular spots like Pulau Harimau and Pulau Mensirip, are vital for conservation. Officials assure the public that closures are routine, but for the tourism industry, it means pay cuts and fewer tours, exacerbated by the approaching monsoon season. Boat assistants like Mohd Najib Abdul Jalik, 41, now earn RM100-120 daily, down from RM160, due to shorter routes. "With the monsoon, we’ll be grounded until February, no trips, no income," he laments.
Tour operators like Nur Nadirah Zainudin of Bluefin Daytrip Mersing have had to adjust packages, replacing closed islands with alternatives like Pulau Seri Buat. Mohd Farez Akmal of mySeahunter Empire notes the overcrowding on remaining islands, a rare occurrence in the past. The number of registered boat operators in Mersing has surged from 200 in 2023 to 355 in 2025, driven by the tourism boom and the state’s Visit Johor 2026 initiative.
To manage this growth, the Mersing District Council launched the Mersing Tourism Operating System (Metos) in 2024, tracking visitor activities. However, it doesn’t impose visitor quotas, reportedly to avoid upsetting tour operators, leaving islands vulnerable to overuse. Mersing’s limited economic alternatives, with tourism and fishing as the main industries, make day-trip tourism vital for locals. "When there’s a shock to the industry, it hits us hard," says Ahmad Firdaus Shaik Omar of the Mersing Tourism Association.
And this is the part most people miss: the dwindling young population in Mersing poses another challenge. Many young locals, ideal for conservation and tourism roles, are leaving for better opportunities elsewhere. "It’s not easy to find young locals to lead conservation projects," says Atteleth Don Peris of Reef Check Malaysia. Julian Hyde emphasizes, "We’re not anti-tourism, but communities must protect ecosystems for sustainable livelihoods."
As speedboats return to the mainland at dusk, the delicate balance between tourism and conservation is evident. Without tourism, locals like Najib might resort to less lucrative work. "If there was no tourism, I’d probably be making keropok with fishermen all day," he reflects.
