Fun and generosity were the order of the day at the Rally for Relief charity match in Melbourne as the world’s biggest tennis stars served up a treat to raise money for the Australian bushfires fund.

Rafael Nadal announced that he and Roger Federer will together donate $172,220 (250,000 AUSD) to support the relief efforts for the wildfires that have so far claimed the lives of 28 people.

“Hopefully that will keep inspiring people to support this terrible disaster that we were going through and helps recover all the things that we need,” said world No. 1 Nadal before taking to the court for a doubles match.

It was announced at the end of the exhibition that $3,324,858 (4,826,014 AUSD) has been raised by Tennis Australia ahead of the Australian Open so far.

Rafael Nadal played alongside Novak Djokovic during the Rally for Relief ahead of the Australian Open.

There was a buoyant mood at Melbourne Park’s Rod Laver Arena as Nadal, Serena Williams, Novak Djokovic, Petra Kvitova and Dominic Thiem defeated Caroline Wozniacki, Coco Gauff, Naomi Osaka, Stefanos Tsitsipas and Alexander Zverev 4-3 in a doubles match.

Players were mic’d up and there was no shortage of antics on the court, including American Gauff single-handedly taking on three players for one point.

A later point saw all four players from both sides take to the court, only for Gauff to finish the rally with a crisp backhand volley.

Firefighters who have been battling the flames were invited to sit courtside for the event, with Deb Borg winning a point while playing alongside Nadal.

Federer then took to the court and defeated Australian Nick Kyrgios 7-6 in a singles match.

“It’s been hard to watch,” said the Swiss star of the bushfires.

“You get it through the news how bad it really is, but then you hear more and more about it and you get the sense that it’s really, really bad. Then you get down here and you speak to the people as well who have been affected – it’s been difficult.

“You wish that doesn’t happen in your country. In Switzerland we’re quite lucky, we don’t have these extreme situations. Always happy to help, always happy to lend my time or my money for that matter. It was an absolute pleasure to be here.”

Kyrgios started a wave of support from the tennis community when he agreed to donate $140 (200 AUSD) for every ace he hits at upcoming tournaments, an offer which has sparked similar gestures from fellow players.

More weather delays

Meanwhile, the Australian Open twice suspended play on Wednesday due to poor air quality and rain.

Practice was suspended until 11am as bushfire smoke – which caused havoc on Tuesday by forcing one player to withdraw from her qualifying match – continued to blow across Melbourne.

“Conditions at Melbourne Park are being constantly monitored and further decisions will be made using the onsite data and in close consultation with our medical team, the Bureau of Meteorology and scientists from EPA Victoria,” said a statement from tournament organizers.

“The onsite data and measurements early this morning were similar to yesterday, when Australian Open practice and play were suspended and delayed.”

Qualifying matches for next week’s grand slam were then suspended later in the day because of heavy rain.
