Diving Martin Island: The Ultimate Guide to Sydney's Only True Seal Dive

Situated about one hour south of Sydney is a one of the most astounding underwater adventures you can do along the New South Wales coastline. Nested about a few kilometres off the coastline from Port Kembla resides a small chain of islands known as the Five Islands Nature Reserve. The southernmost island in the group is Martin Island, technically, not big enough to be called an island, but an islet because of it being just 2.3ha’s in size, so its actual name is Martin Islet.

As winter approaches each June, something truly astonishing occurs to this tiny island that attracts divers back year after year. As ocean waters cool and the days become shorter, life returns to Martin Island. Bird numbers begin to increase, majestic Humpback whales arrive on their northern migration and most importantly for dives, the majestic Australian Fur Seals begin to haul out.

The Seals at Martin Island

Even though you can occasionally find small quantities of seals further north, Martin Island is the most northern significant haul out location on the east coast of Australia. A haul out in basic terms, is a colony of seals, predominantly male, that inhabits a site temporarily in preparation for the next breeding season.

The main colony of seals always inhabits the southern-eastern corner of Martin's Islet, with numerous more individuals dotted in small, more hidden areas along the southern side of the islet. The dive location is chosen on a given day based upon the conditions on that day, the activity of the seals on that day and based upon what dive site will provide divers with the most rewarding experience.

This is definitely one dive like no other. When diving with the seals at Martin Island, Interaction is the key to maximum fun, all the seals want to do is play, they are super curious. If a diver does not play with the seals, then the seals will find someone else that will.

The Underwater World of Martin Island

In addition to the seals, throughout your dive keep an eye out for the giant Smooth Stingrays as they glide along under you. They are nature's cleaners and follow the seals everywhere. Diving Martin Island is worth it just for a chance to dive with these giant stingrays.

Humpback Whales are also a common sight, sometimes remarkably close to the shoreline and the boat. Divers might hear the whales singing or even lucky enough to see one during their dive.
