    StandoutExceptional marine biodiversity

    The 4th-5th Reefs offer a straightforward dive along a coral reef system off Sydney. You'll find a good scattering of hard corals and sponges, with a decent chance to spot various reef fish darting between the bommies. It's a solid choice for local divers looking for a reliable drift, or for those wanting a relaxed introduction to Sydney's offshore sites. Currents can pick up, so keep that in mind.
