From my observations, the Australian Open Court speed has noticeably dropped this year. The main reason for this is the change in court surface, which has been switched to a slower pace to promote longer rallies and a more strategic style of play. The cooler weather conditions also contribute to the decrease in speed as the ball doesn't bounce as high or travel as fast. This has been a major talking point among players who are having to adjust their games accordingly. It's definitely a change that's stirred up the tournament this year.
