Crested terns but which ones?

I know these are Crested Terns but there wasn't any information on the different types of Terns here on the bird finder when looking yesterday.

I saw these at Ricketts Point, Beaumaris, Victoria, yesterday while out on a photowalk.  I believe there are two or three different types.

I don't know if we have both terns here(Lesser and Greater),but if we do these look like the Greater terns to me.

Thanks Nathan. I couldn't find any descriptions on the bird finder so wasn't sure.  And photos in wikipedia look like the same bird for both descriptions.

I did manage to get one reasonable close up of a tern standing on a rock.  It looks like it has a band on one leg. From what I've read, both the lesser and greater terns are in low quantities here in Victoria.

those appear to be Greater Crested Terns, indicators are lemon-yellow bill rather than orange, broad white line between black crown & bill, the bird (3rd pic) with the reduced black crown is in non-breeding plumage; further, I do not believe that the Lesser Crested gets into NSW let alone Vic; when I am back from some leave I will post pics of the 2 species; also if you have a Simpson & Day guide be careful as the sketch title have been mixed up

Thanks, I know it's a crested tern but which one is what I was curious about. I've read that both the Greater and Lesser are endangered here in Victoria but couldn't find out a great deal more. They look very similar to me from the pictures and descriptions I've seen and read.  The bird finder here on this site doesn't give much information about crested terns at all.

Kathie, here's some pics of 1) Greater Crested Tern, adult, today Rottnest Is WA 2) Greater Crested Tern, non-breeding, today Rottnest Is WA and 3) Lesser Crested Tern, non-breeding, 12/2/11 Lady Musgrave Is Qld - I believe that these show the differences between the species
