I see what you mean Leanne. The Triangle type shape from the snout to the eyes is similar as well. The only thing is the colouring of your tadpole's don't look the same for Litoria ewingii. I have some photo's of my Litoria ewingii tadpoles from last spring in my album if you want to cheek them out. They do have quite distinctive markings. May be you could try to get a clearer photo for us.
