MacQuarie Island, sub Antarctica. I was an expeditioner with the Australian Antarctic Research Expeditions for a full year from Oct 1976 to Oct 1977.
The island is twenty-three miles long by three across. It teems with wildlife: 18,000 Elephant Seals. It has Fur Seals, Leopard Seals, and the occassional Hooker Sea Lion and Weddell Seals drop in.
There are four types of penguins: Royals, Kings, Gentoos,and Rockhoppers, their entire population being over 3,000,000 strong.
If you take a look at some of my Hubs you'll get an idea of the place - plenty of pictures.
On top of this you have Albatross of several species- all types of sea birds. Oh, and the scenery is breathtaking in its clarity on a clear, fine day. The air, of course, being the cleanest and freshest in the world.
