Hard to tell from those photographs unfortunately, a lot of frog species identifiers are on the Snout, near the Thighs or on the Belly. From the patterns around the eyes, the colour and the vicinity it was found, it could be a Litoria verreauxi (Verreaux' Tree Frog). This is just a guess, as Karabar may be out of its normal range, although not by far, as it is seen from up above Byron Bay down to the middle of Victoria, primary close to the coast.
