Hastings Reef - Coral Gardens is a boat-access Great Barrier Reef site built around a large wall with several entry points. One route leads into the Coral Gardens area, where the main draw is dense coral growth, including coral trees from reef restoration efforts, plus scattered bommies. The site is best known for its mix of reef structure and easy marine life spotting rather than dramatic depth or penetration. Plan for open-water reef diving, with conditions that can change with weather and sea state.
