Thousands of dead fish have been washing up on the shores of far eastern Victoria and southern NSW. They started appearing on the beach in small numbers around March 11 but came in en masse in the last few weeks of March. Although most of the fish appear to be leatherjackets, there are also whiting, black sole, puffer fish, boxfish, sea urchins, flathead and even some penguins.
