It definitely looks like a metamorph Striped Marsh Frog (Limodynastes peroni) yet to colour up properly, but still with the white and black head markings extending onto the arms and those long second last digits on the feet. L. nasuta is not too far off the mark but the snout is not pointy enough, as already said, and the backlegs are not long and thick enough in comparison to the body. I also don't know of it occurring below just north of Newcastle, but that is not to say it absolutely does not.
