Chief steward Lindsay Lane told News Ltd, before Montgomerie's death was confirmed:
"The stewards are somewhat concerned given the close nature of the riding community here in Darwin about the effect that it may have on the other riders so we've spoken to the riders and some of them are quite concerned and quite upset.ADVERTISEMENT
"I'm sure that the riders can ride at their best but whether they can ride safely with the fall on their mind, the stewards aren't totally convinced. The common sense thing to do is to call the meeting off."
Montgomerie was born into racing. Her father, Peter, trained On A Jeune to finish second behind Makybe Diva in the 2005 Melbourne Cup.
She had been riding for eight years and boasted a career total of 67 wins.
