(contactmusic.com) - Justin Timberlake has donated $100,000 (GBP50,000) to an Australian wildlife fund, paying tribute to deceased crocodile hunter Steve Irwin. The U.S. pop superstar is currently touring Australia on the latest leg of his FutureSex/LoveShow tour. And during a concert in Brisbane on Saturday (27Oct07) evening, he announced plans to give $100,000 to a scheme set-up by Irwin. Timberlake had been given a guided tour of the facility in Queensland by Irwin on a previous tour, prompting the generous gesture. He told the crowd, "When I came here last time, it really hit me...I said to myself: "What can I do?' "So what I did was 50 cents from every ticket sold on the Australian tour goes to Wildlife Warriors." Irwin was killed 12 months ago, when a stingray pierced his heart.
