How are the League Ladder positions chosen. I assumed it would just be on goal difference if points are equal. But this doesn't seem to be the case, see the aussie table below...
Team Points MP W D L GS GA
1 au Collinwood Magpies 18 6 6 0 0 22 10
2 au Melbourne Victory 1 18 8 6 0 2 21 8
3 au Lacy Windgivers 12 7 4 0 3 7 6
