There was lots of barfing at the Australian Open yesterday but it wasn’t food – the temperature reached 42C.  It doesn’t even get that hot in Brisbane, the Tampa of Australia. But other parts of the country are prone to huge temperature fluctuations.

Andy Murray has warned the Australian Open it risks damaging the reputation of tennis after players were forced to play in searing heat in Melbourne.

Canadian player Frank Dancevic and a ball boy both collapsed on court while China’s Peng Shuai vomited then suffered cramps during her defeat as temperatures soared above 40C.

Czech veteran Radek Stepanek also retired with heat exhaustion against Slovenian Blaz Kavcic.
