Blanche Wall - Iron Bottom Sound

Diving the Dauntless in Iron Bottom Sound feels less like visiting a wreck and more like an archaeology dig. We love how intact she is, sitting upright at 13 metres. You can practically imagine pilot Jim Dougherty’s landing. We usually drop onto the wing, then slowly make our way to the cockpit, peering in to see the gauges and controls still there. The real charm here, though, is the macro life. The Dauntless is a magnet for blennies – look closely in the crevices and you’ll spot Red-streaked Blennies peeking out. Tiny Bluestripe Pipefish weave through the coral growth on the fuselage, and we’ve often found a curious moray eel tucked into the bomb bay. It’s an easy, calm dive, usually with 17m visibility, and perfect for photographers who appreciate the details of history and the small wonders of the reef.
