Why dive here
With 263+ marine species recorded in the area - including blue-spotted stingrays, dugongs, giant moray eels, seahorses and sea turtles - I.S.A. 5 offers some of Southern Islands's richest wreck diving. Water ranges 28-31°C, warmest May, June, November.
I.S.A. 5 isn't just another wreck dive; it’s a portal to a bygone era, tucked away in Singapore’s often-overlooked Southern Islands. This lighter vessel went down in 1955, and it’s a proper 'dangerous wreck,' which is exactly why we love it. The wreck sits upright at a comfortable 15 meters, completely colonised by decades of growth. You'll find sections draped in colourful soft corals, like vibrant carpets, and anemones clinging to every available surface. We’ve spent hours here, meticulously exploring the cargo holds, where schools of fusiliers are so thick they sometimes block out the light filtering from above. Keep an eye out for resident batfish that eye you with disinterest, and the occasional moray eel peeking from a dark crevice. Our favourite time to dive I.S.A. 5 is on a slack tide, usually an hour before or after high water; the visibility tends to be at its best then, and you can really take your time examining the intricate details of the decaying structure. It’s a site that rewards slow exploration, perfect for photographers or anyone who appreciates the quiet history of the deep.
