Meet the site
Bonito Reef is a compact ridge of reef off Crackneck Point, the forested headland in Wyrrabalong National Park between Forresters Beach and Bateau Bay. Muddy Puddle Diver records that it was discovered while fishing and describes it as a finger of reef, a ridge running roughly east-west, with the top at 21 m and the base at 25 m. The Terrigal Underwater Group lists it at 25 m and praises its excellent structure, many nudibranchs and good fish life. The ridge form makes for easy navigation: one side out, the other side back. Along the flanks the rock is undercut, with ledges and small overhangs where bullseyes, one-spot pullers and cardinalfish shelter. The top is cloaked in sponges, ascidians and encrusting growth, and it is here, and on the vertical sides, that the site's nudibranch reputation is earned - several species can be found on a single dive by divers who slow down and look closely. Fish life is good for the size of the reef, because an isolated ridge on sand concentrates fish. Yellowtail and silver sweep school above the top, red morwong and blue groper patrol the edges, wobbegongs lie at the base, and in warmer water there is a chance of the pelagics - bonito, kingfish and trevally - that probably gave the reef its name among fishers. At 21-25 m it suits Advanced divers, or Open Water divers with a guide who are comfortable at depth, and it offers enough time at depth for photographers to work. It is a good choice when the Adelaide is busy or divers want a reef with real relief and a strong macro component.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Bonito Reef is recorded as Reef in Central Coast. The listed access is boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
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.

Can I book Bonito Reef through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
