Tanjung Duva Duva - Halmahera

Waterfall Reef isn't always top of mind when you’re heading out to the Poor Knights, but we’ve had some truly magical dives here. It’s tucked away on the channel's eastern edge, and while the maximum depth is only 12 metres, it packs a punch. We love the tall kelp formations that sway with the surge, creating a moody, dramatic feel, especially when the light filters through. Beneath the kelp, the sandy, shell-strewn bottom is a great place to spot some more unusual residents. We’ve found Spotted Stargazers here, just their eyes peeking out, and the flash of a Bluefin Gurnard’s fins as it scuttles away. The key to Waterfall Reef is timing. Easterly winds and swell can really whip up the currents, making it a bit of a workout. We always aim for an incoming to slack tide – it makes getting back to the boat a lot less strenuous. Visibility averages around 7 metres, which might not sound like much, but it often enhances the intimate feel of the site. You’re not looking for grand vistas here, but rather focusing on the smaller details. Keep an eye out for seals in winter, too; we’ve had some playful encounters. This site is perfect for divers who appreciate a more subtle, introspective dive. You’ll spend your time exploring crevices for Crested Blennies and peering under ledges for Kina. It's a fantastic spot for macro photography or for simply enjoying the rich texture of the reef, away from the bigger crowds.
