The whip rules were reformed on the 23rd September 2009 when the Australian Racing Board released a statement saying that two of the rules had been amended, namely that the 200 metre mark was reduced to a 100 metre mark when it comes to the manner of which a rider can use the whip in a forehand manner in consecutive strides, although the whip may not be used on more than five occasions. Furthermore, the rider is able to apply their own discretion when it comes to use of the whip in the final 100 metres along with in compliance with other requirements of racing.
What's more, horse riders will also be monitored for compliance with similar regulations governing when the whip should be applied and in what situations. Namely, a whip is not to be used if a horse is not responding or not in contention for a dividend-bearing placement.
Rules I did not know about till today
