G'Day Topsy,

The point about Sydney racing is the fact that it is dominated by two mega stables and I personally believe that this is a deterrent to future wagering turnover growth.
The average punter hasn't a clue which runner is "trying" when the major stables have a number of starters in the same race.
It is getting so bad that I have increased my betting activities in Hong Kong where the riders are scrutinised to such a degree that the punter feels confident that any transgressions will be dealt with appropriately.

Cheers.
