Meet the site
Indicators is an offshore reef area listed by marinelife.org.au as lying well out from Canal Rocks in 20-30 m, with spectacular walls and caves rich in marine life and fish. The name is shared with a surf break, a reminder that shallow reefs along this coast break in swell and that any boat approach should be made in calm conditions.
Walls and caves at 20-30 m on the open Indian Ocean coast suggest clear water, abundant fish such as western blue groper, dhufish and buffalo bream, and good sponge growth in the shaded areas. With few divers visiting, the reef is likely to be in good condition.
Because only a brief description is published and the position is not given, the site is a matter of local knowledge. It suits Advanced divers with their own boat who are comfortable at 20-30 m in open water and can plan around swell and current. Nitrox helps extend bottom time.
For divers without a boat, the Honeycombs and the sheltered north side of Canal Rocks offer shallower alternatives in calm weather.
The Capes coast between Cape Naturaliste and Cape Leeuwin faces the Indian Ocean and is famous for its surf, which is exactly what makes diving here so condition-dependent. Long-period south-westerly groundswell can arrive on calm, sunny days, and the regional ocean-safety guide advises observing a site in different conditions before diving it, never diving alone and flying a flag near boat ramps.
