Meet the site
Mojo is a snorkel site near the gap between Middle and North Opal, visited by Wavelength Reef Cruises. The operator describes blue staghorn corals, schools of red bass, frequent turtle visits and reef sharks. Its position near a reef gap is what gives the site its energy. Tidal water moving between the Opal reef sections brings plankton and nutrients, supporting healthy coral and attracting fish. The blue-tipped staghorn coral forms extensive thickets in the shallows, providing shelter for damselfish and juvenile fish. Red bass – a large, dark-red snapper – school around the reef, and reef sharks cruise along the edges. Turtles are frequent visitors, feeding on the reef or surfacing to breathe near snorkellers. The current near the gap means the site is best visited when the tide is favourable. Wavelength's skippers choose sites according to conditions, and guides keep snorkellers in areas where the flow is manageable. No depth figures are published; the snorkel area is shallow, with deeper water nearby towards the gap. Divers on a private charter would find a site that suits a gentle drift or an exploration of the reef edge. Wavelength is a snorkel-only operator that runs a single fast catamaran to its own exclusive moorings, carrying marine biologists who guide snorkel tours and give reef talks; the skipper picks three of the company's sites each day according to wind and tide, so no single site can be guaranteed. Scuba divers who want to see the site underwater at depth would need to charter a small-group dive boat, and the site name may not be used by other operators.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Mojo (Opal Reef) is recorded as Reef in Port Douglas. The listed access is boat (day trip). 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.
- 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.
