Curtis, I reckon you are right. I'm confident they are both Common Terns. I assume this was in Ballina recently. We get hundreds of Commons in Ballina at this time of year.
White-fronted Terns are similar but we only get them at Ballina in winter months. Arctic Tern are also similar, I've never seen one, I would expect much shorter legs if Arctic. Finally Roseate Tern are also similar, but I'm confident not that either, I've never seen a Roseate.
I don't know much about Turns, so I have been staring at those for a while and looking at my books, I think the bird on the left in the photo has -red legs-? My Simpson&Day tells me Common Turns have brown mid-length legs?
The bird on the left appears to me to have dark red legs & more reddish than the other bird, but that could be the lighting, & that's normal for Common Terns anyway, their leg colour varies a lot from red to appearing black. The bird on the right appears to have very dark primaries, I believe that indicates 1st year bird.

Thanks Araminta and Steve, your truly an expert!
Araminta, I think they both have the same coloured legs, it was taken very early in the morning, probably the sun shining on it.
