Extreme heat has forced all outdoor matches at the Australian Open to be suspended on Friday.
It's the second day that heat affected play, after the roof at the Rod Laver Arena was closed for the women's semifinals on Thursday.
Firefighters have been put on alert as temperatures are expected to hit highs of 44 degrees Celsius, with forecasters calling it the "hottest day in a decade".

Meanwhile, tens of thousands of people experienced blackouts in southern Australia after the power grid struggled with surging demand.
Authorities said planned two-hour power interruptions to reduce overburdening the gird.
