I was very interested in your article in AG 144 about attacks on humpback whales by orcas. I witnessed a frightening attack last October by two orcas off the coast of Nambucca Heads, on the NSW north coast. It was quite a way offshore and, of course, it was one of the few days I didn’t have my binoculars with me! There was at least one humpback and the two orcas breached in unison and crashed down on the larger whale’s back. I could not see if a calf was present but watched the attack for at least 10 minutes and I don’t know how long it had been going on before I saw it. I have never seen orcas here before and I was pleased to read that it is actually good news because I found it really quite distressing to watch! I have been a subscriber since AG 4 and have found something of interest in every issue.
