Nick Kyrgios made the initial pledge of $200 for each ace on Thursday, before Alex de Minaur, who will star alongside the world No. 30 at the upcoming ATP Cup, replied with his own offer.
World No. 99 Samantha Stosur matched Kyrgios' offer of $200, urging people to"join me in any way you can." The governing body later responded by saying"stay tuned for an announcement soon @NickKyrgios. Great to have your support." Hot, dry conditions and strong winds have heightened the risk of fires spreading in recent days and Tuesday saw seven people killed in the space of 24 hours.
The inaugural ATP Cup takes place across three cities -- Sydney, Perth and Brisbane -- between January 3-12, featuring teams from 24 countries. "There's no rain predicted there for the next four months, so it doesn't look like the fires are going to slow down anytime soon, which is pretty sad. To see Canberra be like that, it's pretty tough."
