I don't have any personal experience with that particular model, but receivers in the same class aren't going to sound different unless one has a significantly superior or inferior amplifier in it. Companies like Denon, Onkyo, Marantz, Yamaha, and Pioneer try to stay fairly competitive. I would also add the Pioneer VSX-1018, possibly the most powerful option in your price range. Depending on it's availability in AU it might be proportionally more cost effective. I am uncertain if that one has upscaling though.
