4. Scorching Heat
The blazing conditions in Australia pose a challenge to players every year. The temperature can go as high as 40 degree Celsius (105 degree Fahrenheit) and the players are forced to make use of braided ice towels. From 1988, Extreme Heat Policy came into picture wherein the match can be halted upon the referee’s decision if the temperature crosses the threshold barrier. As of 2015, the threshold temperature was 40 degree Celsius.
