Australia has confirmed its first mass mortality event linked to the H5N1 bird flu virus, triggering immediate concerns among economists that the outbreak could reignite inflationary pressures if it spreads to the commercial poultry and dairy sectors.

The government’s confirmation marks a significant escalation in the biosecurity threat facing the nation’s agricultural industry.

With the virus now established on the continent, officials are bracing for potential wider transmission across livestock populations.

The primary economic risk lies in the disruption of supply chains for high-demand protein sources, which could drive up grocery prices at a time when households are already sensitive to cost-of-living pressures.

This development adds a new layer of complexity to the monetary policy debate in Australia.

A growing cohort of economists has recently warned that the Reserve Bank of Australia (RBA) may need to deliver one more interest rate increase this year, contradicting market consensus that had largely priced out further tightening.
