Hi all

This argument is a bit like using the weather (particularly Australian weather!) has "proof" of anthropogenic climate change.

All we can say is that a southward movement is consistent with predictions relating to global warming (when will the Grey Nurse Sharks appear in Port Phillip Bay?).

Are there any instances of similar distance northwards expansions of range?

Best wishes
