Meet the site
Big Peninsula, known locally as Big P, is the horseshoe-shaped bay on Great Keppel's north-east point and the island's everyday dive site. It is sheltered from the prevailing south-easterlies, shallow (mostly 12-14 m) and close to the dive base, which makes it the operator's choice for training, refreshers, night dives and days when nothing else is diveable. The bay's reef runs around its edge onto a sandy bottom. Coral gardens line the shallows, with sea whips and sea cucumbers on the sand and rubble. The sand is the place to look for bull rays and blue-spotted rays, and moray eels peer out of the reef edge. At night the site comes alive with crustaceans, hunting morays and sleeping fish. On a running tide the edge of the bay can be dived as a gentle drift, which adds a little variety. Visibility is typical of the inner islands and varies with wind and tide. Big P is not a site to travel for on its own, but it is a comfortable, dependable reef that makes a good first dive in the Keppels, a very good night dive and a place for new divers to build confidence before tackling the outer rocks. Great Keppel Island (Wop-pa to the Woppaburra traditional owners) has been through several phases of resort development and closure, and today the dive operation is small and relaxed, which suits a low-key site like this. Big P is also where many divers first meet the Keppels' olive sea snakes, which are curious rather than aggressive and usually swim away after a close look. Divers staying several days often return here for a night dive once they have seen it by day.

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.
