Racing Victoria has warned jockeys they will face heavy punishment if found to be in breach of the rules this year, according to The Age.
"If a jockey goes over it has to be a significant penalty and they've been made well aware of the whip rule which they ride under every day," Racing Victoria chief steward Robert Cram said.
"Given the magnitude of this race, we know the spotlight is on us.
"The penalty is going to be a significant suspension and fines, but we also have to take into account the magnitude of the breach. We don't want to see what happened last year happen again.
"We'll talk to them before the race as well to remind them of their obligations with the whip and about riding safely. We don't want jockeys flaunting the rules just to win the Melbourne Cup."
