These birds as Crested Terns - Sterna bergii - and they are the tern I most commonly see. In some ways these are my 'default' terns and I find others by noticing that they are not this one!
They are rather more relaxed than some other birds and give photographers a better chance to get close to them.
I am also very fond of them because I saw some on my very first day in Australia!
The flight shots were all taken near Queenscliff and the birds sitting on the jetty are at Swan bay.
