Aidan, the free programs Stellarium, CdC, and C2A (and probably others I don't have) all support in-program updates of their comet and asteroid databases. Provided the data has both the magnitude data values they will estimate the brightness you can expect.
At the moment it is at 17h26'03" -39°54'54" mag 9.2 visible from a bit after 03:00 AEDT.
Your best chance is probably in the fortnight around Jan 25 when it will be in the morning sky around 02:45 AEDT. CdC predicts Jan 18 mag 8.1, Jan 25 mag 7.4, Feb 1 mag 6.6.
