HI all,
The first frog could iher be Litoria rothi or L. peroni...without a side on shot it is hard to confirm..distribution may help
The next few frogs are O. ornatus the genus recently validated by the work of Frost in the USA(the Australian component was mainly done by Steve Donnellan).
The last frog looks like Limnodynastes terrareginae, they are often transported around in plants etc.....also a note on distributions.....many books have faults, different resources give different results.....eg if you search a species distribution on a Museum site you get the records for that Museum or that wildlife dept etc.
They do not take into account translocated specimens.
Cheers,
Scott Eipper
