Hi @KMcCue, thanks for the record! Do you have any photos that show more/close-up features of the animals? While they are very likely to be Australian fur-seals, I would be good to have definitive photos. All the best.
That's the only photo I have. My limited knowledge suggests that the only other animal they could be is a New Zealand fur-seal. Should I have left it at fur-seal though, like you, I assumed they are more likely to be Australian fur-seals. Unlikely to be Australian sea lions or immature Elephant seals - anything else?
