Just had a look at nsw tab and found following results
Sydney swans were as high as $2.05 head to head when betting opened(centrebet $2.08 before hall got off )
Sydney 1-19 margin =$5
Sydney to win premiership $35 on May 2

NQueensland half time margin 9+=$9.00
Fulltime margin 13+=$10


anyone out there got opening or highest prices for syd/westcoast gfinal or
wests/nq grandfinal quinella(they would have to be 100-1+ at beginning of season.
cheers
