Well i saw/didn't see

the brightest flash in the sky this morning at around 4:15 4:20 am.
I was imaging M42, and was watching a satellite coming from the north, I looked at the exposure time on the lcd screen when i noticed a flash in the corner of my eye.
It wasn't that big so i didn't bother looking for what it was, as a night of viewing has numerous flashes all over the sky.
A second or so later my whole back yard lit up brighter than day, i actually freaked out at it's intensity, and turned to see a dust, smoke, debris trail in the sky at least 25 degrees long.
It was awsome even seeing this smoke trail, it lasted only seconds then vanished into the background.
It was heading south about 50-60 degrees above the horizon.
Did anyone else from Melbourne see this this morning?
