On a Friday in September, a government ranger discovered a dead Australian sea lion at Seal Bay on Kangaroo Island — an animal already weakened by a shark attack, now confirmed as South Australia's first H5 bird flu fatality in the species. The finding is more than a single death; it is the arrival of a pathogen at the doorstep of one of the world's most precarious wildlife populations. With fewer than 12,000 Australian sea lions remaining globally, and 85 percent of them living in South Australian waters, the distance between one loss and a conservation catastrophe is uncomfortably short.
