It looks most like Litoria peronii, including what appears to be the distinctive feature of a criss-cross pupil. However due to the image quality it's hard to give a positive ID for this sighting beyond doubt. Other features ideally needed to confirm this species are tiny, emerald-green specks on the dorsum and yellow and black blotches in the groin, which can't be seen in the photo provided. I'm happy to leave it as probably Litoria peronii TBC
