The Cathedral (aka Cathedral Reef) is a dive site situated on a reef that runs East to West on the eastern edge of the main shipping channel. The top of the reef is in 20 plus metres, most of the dive at this site will be spent in the 30 to 40 metre range.

The name arises from the fantastic Pinnacle and Bommies that rise 4 or 5 metres above the top of the reef. There is also a huge cave at 32 metres, with a swim-through at the back, leading out to the top of the reef. This site can only be dived when there is no shipping and at slack water at the end of the ebb tide.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
