Meet the site
New Seagull is an exposed Opal Reef site with open ocean exposure and a buttress reef structure, according to Wavelength Reef Cruises. The operator visits it seasonally, during calmer periods in the wet season when the trade winds ease. Buttress reefs – often called spur-and-groove – form on the seaward faces of outer reefs, where wave energy shapes the coral into ridges (spurs) separated by sand or rubble channels (grooves). The spurs are covered in robust corals adapted to wave action, and the grooves channel water and sediment. The result is a dramatic landscape of coral ridges running out towards deeper water. The exposure to open ocean means clear water and a chance of pelagic fish – trevally, mackerel and reef sharks – along with reef fish sheltering among the buttresses. The coral on the spurs tends to be robust, with massive and encrusting forms. Because of its exposure, New Seagull can be visited only in calm conditions; during the south-east trade season it is usually too rough. No depth figures are published; the snorkel area is on the upper spurs, with deeper water beyond. 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.
New Seagull (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.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
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 New Seagull (Opal 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.
