Hi camisha and welcome!
Can you describe exactly what you saw? Did the light across in the sky.
Also what was the time? It looks like about 15-20 minutes before dawn.
And you are looking almost East from Melbourne?
Probably not Comet Holmes, but rather a satellite - we can try to work out which one. Might even be an aeroplane reflecting the sunlight. Still, we can check out where the comet was at that time.
