Social media stars and sporting champions are splashing the cash for Australian bushfire relief efforts and urging fans to do the same.
Twenty-six people have died since the start of the disaster in September, more than 2,000 homes have been destroyed, and some eight million hectares (80,000 square kilometres) has burned -- an area roughly the size of Ireland or South Carolina.
- Aussie A-listers donate -
Australian Marvel actor Chris Hemsworth said he would donate AUS$1 million, singers Kylie and Danni Minogue pledged AUS$500,000 to the country's rural firefighters, a donation matched by Nicole Kidman and her husband Keith Urban.
Compatriots including Russell Crowe -- who used his Golden Globe win to speak about the tragedy -- and Rebel Wilson have pledged donations, with singer Dami Im also donating.
- Serena plays for charity -
Athletes like Lewis Hamilton, tennis players Ashleigh Barty, Maria Sharapova and Novak Djokovic, and cricketers -- including Chris Lynn and Glenn Maxwell -- offered to donate their winnings.
On Wednesday, organisers of the Australian Open said Roger Federer, Serena Williams and Rafael Nadal will headline a charity match ahead of the tournament.

Many celebrities will auction clothes: Williams is donating a signed dress, while British actor and writer Phoebe Waller-Bridge announced her Golden Globes suit would be auctioned off, and Shane Warne sold his baggy green cap to an anonymous bidder for AUS$1 million.
