Although it's not the best photo (no offence) to go on, I reckon it's most likely to be Litoria dentata. The main reasons being general morphology, which is largely about proportions, sometimes subtle and in this case looks just like the Litoria dentata that I've seen. The relatively narrow head is proportionally smaller compared to the relatively plump, rounded body and features unlike the other Litoria sp., at least in this part of the country.
