Australias greynurse shark population is in decline, on the brink of extinction. It began in the early 1960s, fed by the false belief that this shark was a man-eater, and, its own physical makeup, a nasty looking set of ragged teeth.
Ben Cropp hosts this documentary and there is no better choice, for Ben was the most famous of the '60s shark hunters, who then swapped his killer spear for an underwater camera, and began capturing the greynurse on film instead of as trophies.
Of the 57 known shark gutters along the New South Wales coast where thousands of greynurse once schooled, the population is now 292 and falling. Join Ben as he re-visits locations off Sydney Harbour to examine a surviving family of greynurse sharks in a hidden cave just metres off shore and study their little-known behaviour.
