A dead seabird on a Queensland beach has quietly marked a threshold: the H5 bird flu virus, already present across three other Australian states, has now arrived in Queensland. Found on Moreton Island in mid-July, the petrel was less a surprise than a confirmation of what authorities had long anticipated. No poultry have been infected, and the risk to human health remains low — yet the moment carries weight, reminding us that nature moves on its own timetable, indifferent to the boundaries we draw.
