    Shark Bank is one of those places where the name tells you exactly what to expect. We love a dive site that delivers on its promise. Dropping down, you hit the top of the bank around 25 metres, and it’s immediately clear this isn’t a gentle drift. The currents here can be robust, so it’s definitely one for divers comfortable in a bit of a washing machine. But what a payoff. We’ve had dives here with grey reef sharks patrolling the thermocline, their sleek bodies ghosting past. Convict fish swarm across the reef, a living carpet of stripes, and we’ve often seen barracuda schooling, a silver wall that melts away as you approach. The coral itself, a mix of brain and staghorn, feels ancient, providing shelter for colourful wrasse and the occasional spotted hawkfish. Visibility averages a decent 20 metres, but on a good day, it stretches further, letting you watch the action unfold at a distance. Our favourite trick here is to find a sheltered spot and just watch the current-swept reef pulse with life. It's a proper blue water experience, a great option for experienced divers looking for big fish encounters and a lively drift.
