    StandoutExceptional marine biodiversity

    South Tip. It's one of those sites where we almost always find something new, even if it's just a different perspective on something familiar. The reef structure itself is interesting, a jumble of granite boulders creating channels and swim-throughs, but it's the smaller stuff tucked into every crevice that really gets us. We love drifting along, peering into the shadows for a Blackside Hawkfish perched on a coral head, or spotting the distinctive profile of an Imposter Fangblenny zipping between polyps. It’s not usually a big fish site, though a chambered nautilus has been known to make an appearance – a genuinely special encounter if you’re lucky enough. Our favourite time to dive here is mid-morning, when the light plays through the water just right, illuminating schools of Blue Green Chromis dancing above the reef. Current can be a factor, so listen to the brief; sometimes it’s a gentle drift, other times you’ll be tucking in behind boulders to observe the tiny wonders like Ernie's Sueviota. If you’re a macro lover who enjoys a bit of a treasure hunt, this spot is perfect.
