The top ants remind me of slave making species a bit, but not knowing what Australian ant species may be slave makers, it is only a wild guess. They do look very much like a Formica species, or perhaps a similar related species. Their long legs could suggest Aphaenogaster; but I am still more inclined to say Formica.
The queen ant looks a little like a Camponotus, though again I cannot say which exact species she may belong to I wish we had a comprehensive list of antipodean ant species, and it would be nice if we had an Australian ant expert to help out, as there must be quite a few good entomologists down under
The first ant is definitely not Myrmicinae but is most likely Formicinae and possibly Dolichoderinae, I think maybe a Camponotus or Cataglyphis. The second is definitely a Camponotus, maybe C. nigriceps, although I think they are a bit bigger than 15mm.
