All 3,000 tickets to Steve Irwin's memorial service at Australia Zoo have been snapped up by fans in just 15 minutes. The naturalist was killed last week (04SEP06) when a stingray barb stabbed him in the chest as he dived off the Great Barrier Reef near Cairns in Australia, while filming a new TV show. Irwin will be remembered by fans at a service that will be televised at the Queensland zoo's Crocoseum next Wednesday (20SEP06). Grieving fans camped for days outside three locations to gain tickets.
