The 14 teams playing in the Rugby League World Cup have pledged to raise funds for the victims of Australia's bushfire disaster.
The initiative has been organised by former Hull KR forward Clint Newton, who is playing for the USA.
Newton has family and friends in the Blue Mountains area of New South Wales where dozens of fires continue to cause devastation.
The teams have donated signed jerseys which will be auctioned off to support the Salvation Army, which has begun the task of rebuilding the lives of those who lost their homes.
The NRL is supporting the appeal and will host the auction, which runs for the length of the tournament, on their website.
Newton, who left Super League at the end of last season to rejoin Penrith Panthers and will play for Newcastle in 2014, said: "After discussing it with my USA Tomahawks' team-mates, we felt it was important to give back to the local communities back home.
"The response from the other nations and the NRL with regards to their willingness to help, however possible, is a credit to all involved.
"It shows how much these events have affected players and the rugby league fraternity because every team here has members who have strong ties to the Australian people who have been so deeply affected."
