Reef Dive | Boat access
Depth: 6 m (20 ft) to 15 m (49 ft)
Level: Open Water and beyond.
Big Reef is a boat diving site which lies about 1.2 kilometres south of Point Danger, near the city of Portland, on Victoria's Discovery Coast.
Big Reef can be easily overlooked (on the way to somewhere else), but it offers a vast array of interesting dive opportunities. The reef was once a massive contributor to the commercial abalone catch in the area. That is sadly no longer the case, but there is still plenty to see (both marine life and underwater scenery) on the right day.
The eastern side of Big Reef drops quickly from 5 metres to 15 metres deep. The western side drops away more gradually.
Location: Portland, Victoria 3305
Ideal Conditions: This dive site is very weather dependant. Best dived in good conditions with a low swell with light winds. See WillyWeather (Point Danger) as a guide for the tide times and the height of the tide.
Divers have the opportunity to catch Abalone at this dive site. Remember your catch bag, legal abalone tool, current Victorian Recreational Fishing Licence, and abalone measure. Please abide by all current fishing regulations if you intend to catch abalone.
Divers have the opportunity to catch Southern Rock Lobster (aka Crayfish) at this dive site. Remember your catch bag, current Victorian Recreational Fishing Licence, rock lobster measure, and cray tags. Once you get back to the dive boat, or shore, make sure you clip the tail and tag your Crayfish as per Fisheries requirements. Please abide by all current fishing regulations if you intend to catch crays.

Traditional Owners — This dive site is in the traditional Country of the Gunditjmara people of far south-western Victoria which continues over the state border into a small part of south-east South Australia and is bordered by the Glenelg River to the west and the Wannon River in the north. This truly ancient Country extends 100 metres out to sea from low tide and also includes Deen Maar (aka Lady Julia Percy Island) where the Gunditjmara believe the spirits of their dead travel to wait to be reborn. We wish to acknowledge the Gunditjmara as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging.

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.
