What sort of frog...

[amy]

I don't expect anyone to give me an answer as i don't have any pictures and the description is pretty sketchy, but i thought i'd give it a shot anyway.
I live in the Hunter Valley, NSW, Australia, our house is pretty much surrounded by swampland, so at night we get hundreds of little frogs on the windows, around the pool, in the bathroom. They range from around 2 cm to 5 cm. They're greyish/greenish in colour and are extremely cute. Yet again, sorry for such a sketchy description, but i thought someone might have an idea of what sort of frogs they could be.

I did a bit of research on the net and found a frog that is similar looking to the one i'm talking about. I don't think it's the same one though, they look a little different and their calls arent the same.

The frogs here just have a normal croak.

he may just be this type of frog that you posted, because frog colourings all vary with the habitat you have them in, and same with the noise they make
