Meet the site

Seal School is Scuba Doctor's name for the dive on the northern side of Kanowna Island, where the juvenile fur seals congregate in the kelp gullies and the sheltered water between the island and the Prom, and it is the alternative to the Seal Colony dive when a southerly swell is running onto the island's exposed face. The terrain is the same: a granite boulder slope thick with kelp in the shallows, broken into crevices and gullies, levelling at about 25 m before the sand drops to 40 m. The difference is orientation and mood. Facing north, the site takes less swell and is diveable on south-westerly through south-easterly winds, and because it is where the young animals gather, the seal encounters here are the most playful on the island – groups of pups and yearlings that treat divers as something to be investigated, mouthed and out-swum. Beneath the kelp the rock carries the usual exposed-Prom encrusting community of sponges, ascidians and bryozoans, and crayfish are present in the ledges; fish are sweep, butterfly perch, wrasse, morwong and leatherjackets, with bullseyes in the shaded gutters. Visibility is generally very good. New Zealand fur seals occur among the Australian fur seals here. Everything that applies to the colony dive applies to Seal School: the island is inside the marine national park, the breeding colony is protected by vessel exclusion zones that are larger in November–January and whose exact distances should be confirmed with Parks Victoria, white sharks visit the colony, and the site is reached only by private or club boats on calm days from Tidal River or Port Welshpool. As a pair, Seal School and the Seal Colony give a boat two seal dives on the same island in different conditions, and either would rank among the best big-animal dives in south-eastern Australia.

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.
