Meet the site
Coral Corner, on the north-western tip of Split Solitary Island, is often cited as the clearest single demonstration in the whole Solitary Islands Marine Park of the overlap between tropical and temperate marine ecosystems that makes this stretch of the NSW coast so unusual. The terrain here is generally flatter than the rest of the island, shaped into a series of small bays separated by rocky headlands, with depths running a gentle 10-15 m and occasional deeper pockets to about 18 m. What makes the site distinctive is the close juxtaposition of kelp beds — a distinctly temperate, cool-water habitat — growing in water as shallow as 18 m alongside profuse growths of plate coral, in places only a few metres apart, a combination that would be unusual almost anywhere else on the Australian coast. Coral life is abundant within the sheltered bays themselves, while the rocky headlands separating them support a denser invertebrate community, and turtles are commonly found resting in the shallows between dives. Because the terrain is gentle and current is generally mild, Coral Corner is an easy, approachable dive suited to less experienced divers, and its combination of coral gardens and kelp forest in a single dive gives it genuine interest for anyone curious about the biogeography of this transition zone between the tropical Great Barrier Reef province to the north and the cooler temperate reefs of southern NSW. It is regularly worked into a day's diving at Split Solitary Island alongside the more turtle- and macro-focused southern sites.

Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
