Snorkelling with the seals at Montague Island. Experience the joy of swimming with these cute creatures with a feeling of amazement at the friendliness of these furry fun-seeking seals. It's an easy swim with most of the seals sunbaking on the surface within 20 metres of the anchored boat. The colony consists of up to 1,600 seals during the cooler months (June to mid-December). During the summer months, there are 500 to 800 seals at Montague Island most of these are either rogue or non-competitive seals rejected from the Southern colonies. All are male and this is a non-breeding colony, hence the island has no shark problem because sharks tend to only feed on small pups that haven't yet learnt to swim properly.
