Malachy Tallack is from the Shetland Isles, as far north in Scotland as you can go. He attracted a lot of attention with his first book, 60 Degrees North, an account of his journey around the world along the line of the 60th latitude. It was a book that Robert MacFarlane described as brave and beautiful, chosen by BBC Radio 4 as Book of the Week. He was in Australia to promote his new work, The Un-Discovered Islands, a study on islands of imagination, deception and human error. Also well-known as a singer songwriter with four albums to his name, in the final ten minutes of this podcast Malachy plays a couple of his songs.
