Actor Russell Crowe is auctioning off his sweaty, and sooty, Rabbitohs cap to raise funds for the Rural Fire Service.
Crowe, who owns a property near Coffs Harbour, has been openly emotional about the effects of the recent fires.
And, while his house was saved by firefighters, bushland on the property was badly affected.
Now, he is pledging to triple the highest bid on the hat and donate all money to the RFS.

Crowe released footage of a New South Wales forest scorched by bush fires on Tuesday and says he has received a bid of more than $4500 for the hat so far.
The first bid came from an international bidder at $500 USD, before Triple M's Lawrence Mooney raised the stakes to $2000.
Bids are continuing to rise, with the auction set to end at 7.21am AEST on Friday morning.
Currently, more than 150 are burning across NSW with more than 2200 firefighters working to slow the blazes.
"With more than 150 fires burning across #NSW and the forecast of more hot and windy weather for the weekend please use this time to prepare. Review your bush fire plan, prepare your properties and discuss as a household what you will do if threatened by fire," the NSW Rural Fire Service tweeted.
On Thursday morning, 64 of the 157 fires across NSW were uncontained.
The Bureau of Meteorology said lightning strikes from thunderstorms which hit Sydney and the state's northeast on Tuesday had sparked fresh blazes, with an estimated 100 new fires igniting in a 24-hour period.
