Secluded lagoon bay with coral, turtles and a 1965 tuna-boat wreck, reached only on foot or by boat.

A year-round grey nurse shark colony in a sheltered 7 m valley that Open Water divers can do – Manly's answer to Magic Point.

Compact pinnacle packed with Lord Howe endemics – doubleheaders, McCulloch's anemonefish – plus a resident green turtle.

Playful fur seals, a large swim-through cave and old practice bombs on a multilevel reef beside the Wandra wreck.
Visibility above 20 m, something large to frame (a wreck, a wall, a shark) and light: shallow tropical reefs at midday or temperate sites on a winter high-pressure day.
