Shane Warne's baggy green cap sold for a record 1,007,500 Australian dollars in a fundraiser for bushfire aid in Australia.

Legendary spin bowler Warne auctioned off his iconic baggy green cap – exclusively awarded to Australia's Test cricketers – to raise money for bushfire victims.

Australia great Warne, who is second on the all-time list for Test wickets with 708, tweeted: "Thank you so much to everyone that placed a bid & a huge Thank you / congrats to the successful bidder - you have blown me away with your generosity and this was way beyond my expectations!
