Chris' Wall, just off Sydney, is one of those sites we always recommend for a solid, reliable dive. It’s a boat dive, and honestly, the ride out sets a nice tone for the dive to come. The wall itself doesn't drop to insane depths, topping out around 21 metres, which means it’s perfect for open water divers who want to experience a proper wall dive without the pressure. We love just drifting along here, keeping an eye on the wall's texture and the small things tucked into the cracks. You'll definitely spot moray eels peering out, and we’ve had some cracking encounters with fiddler rays cruising over the sandy bottom at the wall's base. Visibility averages around 8 metres; it’s not always Caribbean clear, but it's enough to appreciate the scale and the life here. Our pick for finding nudibranchs is often around the bommies that sit on that sandy expanse – slow down and really look. For a Sydney dive, it’s a consistently good choice for a relaxed exploration, suitable for pretty much anyone looking for a pleasant day out.
