(SOUNDBITE) (English) NICK KYRGIOS SAYING: "It's been an emotional couple of weeks, obviously.
Through the ATP Cup, and practically while I was playing so hard, I just wanted to send a message to these guys.
I just had dinner and I wrote the tweet I said, that was the opportunity for me to use my platform and then the whole Aussie team got behind me, and obviously Alex Di Minaur, John Millman and all those guys, I woke up the next day and it kind of exploded, and it was so emotional back home when I was in Canberra, couldn't even go outside.
You know, it was emotional, I'm just so happy that we had Roger, Novak, Rafa, some of the greats to get behind it, everyone around the world, the awareness has grown and I think we're doing everything we possibly can to overcome this together." 20.
(SOUNDBITE) (English) REPORTER ASKING ROGER FEDERER: "How hard was it for you over the last few months watching from afar, seeing these harrowing images?" 21.
(SOUNDBITE) (English) ROGER FEDERER: "It's been hard to watch, you know.
As you did get it through the news, you never know 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, and then you get down here and you get to speak to the people as well who've been affected.
It's been difficult, you know, you wish that this doesn't happen in your country.
In Switzerland, we're lucky we don't have these kind of extreme situations, so, always happy to help, always happy to lend my time, or my money for that matter, and it was an absolute pleasure to be here tonight with Nick and all the other legends of the game and at least, do my fair share." 22.

ALL THE PLAYERS POSING FOR PHOTOS WITH THE FIREFIGHTING TEAM (2 SHOTS) STORY: Tennis greats Roger Federer and Rafa Nadal pledged A$250,000 ($172,000) towards the Australian bushfire relief efforts at a charity event on Wednesday (January 15) in the leadup to the Australian Open.
World number one Nadal made the announcement at Melbourne Park's Rod Laver Arena during the "Rally for Relief" event where top players including Serena Williams and Australian Open defending champion Novak Djokovic led fundraising efforts.
"Hopefully that will keep inspiring the people to support this terrible disaster that we're going through and helps to recover all the things that we need," Nadal said on court after an exhibition match.
Australia is experiencing one of its worst bushfire seasons on record, with fires burning for months and killing 28 people, destroying more than 2,500 homes and razing forests and farmland the size of Bulgaria.
Smoke from bushfires blanketed Melbourne in a thick, grey haze on Wednesday before a clearing rain-storm, disrupting the Australian Open's qualifying matches for a second successive day.
The ATP on Sunday (January 12) pledged $500,000 to the WWF Australian Wildlife and Nature Recovery Fund as part of the bushfire relief efforts.
A number of players have made individual pledges including American Williams who said she would donate all her prize-money from winning a tournament in Auckland on Sunday.
Australian Nick Kyrgios has pledged A$200 for every ace he hits this month.
