Australia’s agriculture sector and food system produce enough food to feed more than 70 million people worldwide. The system is one of the world’s least subsidised food systems. It has prospered under a global rules-based system influenced by Western liberal values, but it now faces chronic challenges due to rising geopolitical tensions, geo-economic transitions, climate change, deteriorating water security and rapid technological advances. The world is changing so rapidly that the assumptions, policy approaches and economic frameworks that have traditionally supported Australia’s food security are no longer fit for purpose. Potential conflict in the Indo-Pacific is driving enhanced preparedness activity in Australia’s defence force, but that isn’t being replicated across the agriculture sector and food system in a coordinated manner. Food hasn’t featured as a priority in the public versions of the Defence Strategic Review or the National Defence Strategy. This has created a gap in Australia’s preparedness activities: if Australia’s national security and defence organisations are preparing for potential conflict, then Australia’s agriculture sector and food system stakeholders should also be preparing for this period of strategic uncertainty.

Food security is a pillar of whole-of-nation preparedness for an uncertain future. While current targeted preparedness efforts and resilience mechanisms are valuable, they aren’t sufficient. Stakeholders are calling for stronger, proactive national coordination from the government to empower and support private-sector action. Meeting that demand is essential to strengthening overall resilience. So, too, is understanding that Australia’s food security relies on a holistic and interconnected ecosystem rather than a fragmented supply chain. Australia is a heavily trade-exposed nation that exports 70% of production, so any disruption to maritime and other transport corridors or to the infrastructure needed to move food risks undermining both national food security and Australia’s standing as a reliable global supplier.

This work has been written and constructed as a Green Paper, not an academic publication. Informed by six months of consultations with government, the private sector and civil society, the paper combines applied policy analysis and real-world insights to promote deliberate conversation about protecting Australia’s food security with the same priority as protecting Australia’s national security. The Green Paper is divided into four parts. It also includes three case studies in the Appendix, which use a threat and risk assessment to analyse three critical inputs to the food security ecosystem—phosphate, glyphosate and digital connectivity—to help stakeholders evaluate the vulnerabilities in Australia’s food security ecosystem.

The intention of this Green Paper is to deepen understanding of food security as a key public policy issue, stimulate public discussion, inform policymaking and provide both government and key stakeholders with policy options for consideration. This Green Paper’s 14 recommended policy options have been designed to equip governments and the private sector with structured national-security-inspired assessment tools and a framework to continuously identify, prioritise and mitigate vulnerabilities. That includes options to centralise the coordination and decentralise delivery of preparedness activities, establish accountability and embed food security as a national security priority and a key element of Australia’s engagement across the Indo-Pacific.
