Since Surround won in 1976, 12 fillies have contested the Cox Plate.

Most of the fillies since Surround have been sent out at big prices and given little hope.

Of those in the market, Tristanagh ($5.50) ran 7th and Courtz 10th ($9) in 1989; while Society Bay ran 11th after being sent out a 10/1 chance in 1986.

Miss Finland was a $10 hope(6th in 2006).

All of the other fillies to contest the race in that time have been at 20/1 or greater.

On the Sires side of things for SM, Australia's top sire Redoute's Choice has never produced a G1 winner, [male or female] in an open to all-comers WFA event.

Considering the history for fillies in the Cox, I'd want better than 10/1 for SM.
