The Convergent Approach to Northern Critical Infrastructure Security
Australia's northern region holds immense strategic importance within the national security framework, with critical national infrastructure playing a pivotal role in supporting the country's defense capabilities. However, the evolving landscape of digital communication technologies has introduced new threats to these infrastructures, posing risks to Australia's overall national security.
Critical national infrastructure encompasses essential capabilities, networks, and facilities that, if compromised, could significantly threaten the nation's security. The expansion of such infrastructure in Northern Australia presents the federal government with a unique opportunity to proactively collaborate with private-sector providers on cybersecurity measures. By addressing vulnerabilities in supply-chain relationships, we can better identify, understand, and mitigate potential risks.
The government's 2020 defense strategic update highlighted the need to be prepared for conflicts in the contested Indo-Pacific region, emphasizing the urgency of bolstering defense capabilities and critical national infrastructure in the north. To support this vision, the government announced an additional $2 billion in funding for the Northern Australia Infrastructure Facility, recognizing the vital role of critical infrastructure in safeguarding national security.

Recent amendments to the Security of Critical Infrastructure Act 2018 underscore the supply-chain implications of cyberattacks on critical infrastructure providers. Northern Australia, although home to just 5.6% of the population, hosts significant industries such as iron ore, zinc, lead, beef cattle, bananas, and mango crops. These infrastructures are not only crucial for economic growth and food security but also directly support local communities and defense facilities.
The 2022 cyberattack on JBS Foods demonstrated how cyber threats could have far-reaching supply-chain consequences. A similar attack on critical national infrastructure in the north, such as gas or water facilities, could severely disrupt defense bases reliant on their services. Learn More
While cybersecurity is essential, implementing it poses challenges. The amendments to the SOCI Act have raised concerns regarding government interference, as it grants the authority to access, modify, or delete data at its discretion. Moreover, a one-size-fits-all cybersecurity approach may not be adequate, given the diverse cyber complexities faced by different industries, especially in the north.
To address these challenges, the proposed Security Legislation Amendment (Critical Infrastructure Protection) Bill takes steps toward tailored cybersecurity measures for systems of national significance. However, it remains unproven in its effectiveness, necessitating further policy action, especially in northern Australia.
Critical infrastructure providers in the north rely on SCADA systems, which have become vulnerable due to their integration with advanced communication technology. Patching these vulnerabilities is complex and risky, requiring a more comprehensive approach. Learn More
Encouraging a "security convergent" approach within each provider offers a potential solution. By holistically considering all security domains, this approach enhances internal awareness of vulnerabilities and strengthens critical infrastructure supply-chain relationships.
In light of these challenges, the government should incorporate convergent cybersecurity development and training into its northern infrastructure investments. Addressing security standards early on will ensure the protection of critical national infrastructure in the region, strengthening Australia's overall national security.
In conclusion, as digital threats continue to evolve, it is essential to adopt a hybrid and convergent approach that considers the broader security network. With mindful and proactive measures, Australia can safeguard its future and protect its critical national infrastructure in the ever-changing landscape of national security. Learn More
