Tennis Australia has announced Roger Federer, Rafael Nadal, Novak Djokovic and Nick Kyrgios will play in a charity tournament to raise money for bushfire victims.

Twenty-five people have been killed in this season's bushfires and almost 1,900 homes have been destroyed.
Australian Open tournament organiser Craig Tiley told reporters on Wednesday that Naomi Osaka, Caroline Wozniaki and Stefanos Tsitsipas will also take part in the event.

'It is heartbreaking to see the devastation the bushfires are wreaking across the country and to see so many people and communities suffering,' he said.
'The Aces for Bushfire Relief initiative gives the tennis community the opportunity to galvanise our sport to support and raise much needed funds to help those who are most in need.'
'For a period of about two-and-a-half hours we're going to be showcasing the game, but also coming together as a community to play our part in the relief effort.
Nick Kygios has already pledged $200 for every ace he hits during his upcoming tennis tournaments.
