H5N1 bird flu spreads from seabirds to backyard poultry and pets, exposing gaps in One‑Health surveillance and biosecurity

Molecular sequencing confirms that the H5N1 strain in Australian seabirds shares clade characteristics with Eurasian lineages, suggesting migratory convergence zones as hotspots. Epidemiological modelling indicates that even low‑frequency contact between wild birds and backyard flocks can sustain transmission chains. Robust, interdisciplinary research is essential to map these pathways accurately.
The emergence of H5N1 in Australian seabirds and its spillover into backyard chickens and cats reveals a cascade of systemic failures—from climate‑driven migratory shifts to fragmented surveillance that excludes Indigenous custodians and smallholder voices.
Historical precedents show that without addressing the structural nexus of wildlife, intensive farming, and global trade, reactive culling merely postpones the next wave. By weaving Indigenous ecological knowledge, cross‑cultural community monitoring, and robust scientific modeling into a unified One‑Health architecture, we can pre‑empt zoonotic jumps. Equitable biosecurity support and inclusive governance mechanisms will redistribute power, ensuring that those most affected become active participants in disease prevention rather than passive victims.
