I don't think you will see it very well from that far south David. It only gets 32 degrees above our northern horizon here and we're about 26.5 degrees south. I haven't seen it but its on my list to see and image for the season.
Info: around 40 arcminutes in diameter (1.3 moons), mag 5.5-6.4 depending where you read, but its surface brightness is only mag 14. Being a face on spiral its stellar equivelant mag is spread out over quite an area severely lowering its brightness.
