Protected from swimmers, so it exists purely as an aerial image, and it has become the single most-used photograph in Australian tourism. Discovered by a pilot in 1975. Its protection status means nobody has ever snorkelled it. A viewing platform on a neighbouring reef was added so visitors could see it from sea level without touching it, a useful reminder that some hotspots are look-only. Anchorage: Hardy Reef has moorings and a pontoon; the heart itself is viewable only from the air. Hazards: No site-specific hazards noted, brief normally. Plus
