Best Shooting Star Ever

On my way back from Steak & Kidney around Ulladulla at 6:14pm (today 31/3/7). It was only just getting evening. The auto switch on the car switched on the lights, the sky was still a light blue and visability was still good. From north to south there was the most amazing shooting star. It shot across the sky with a blue/white colour and a long tail behind. It travelled in a straight line and it disintegrated somewhere further south. The speed of it must have been amazing fast, many times the speed of a jet airplane. The whole spectacle lasted only about 4 sec. The blue/white light was extremly bright. Much much brighter than any airplane is during landing. Perhaps it wasn't a shooting star but an astroid or perhaps a bit of space junk such as a satelite. Will scan Google to see if anyone else has seen it.
