On 3 July the Department of Home Affairs launched a month-long public consultation on draft amendments to the Security of Critical Infrastructure (SOCI) Act 2018 – legislation that already requires owners of Australia’s airports, ports, energy grids and data centres to report cyber incidents and maintain robust risk-management programs. The proposed ‘Tranche 2’ reforms aim to reduce regulatory duplication, modernise sector coverage and streamline assurance obligations. While not an immigration instrument, the SOCI Act carries major implications for multinational companies that base staff on Australian critical-infrastructure sites or provide managed services into those environments. Under current rules, foreign investors must pass a detailed national-security test and often accept conditions limiting remote access to operational technology. The draft amendments promise clearer statutory concepts and guidance, potentially shortening approval timelines for mobility projects that involve fly-in/fly-out engineers or expatriate IT specialists.

At this intersection of infrastructure security and cross-border staffing, VisaHQ can be an invaluable partner; its dedicated Australia portal provides rapid processing, document-checking and real-time status tracking for the temporary work visas often needed by fly-in/fly-out engineers and cyber-security consultants, helping companies keep project timelines on track while they navigate evolving SOCI obligations.
The consultation paper suggests introducing tiered obligations based on a facility’s criticality, a move that could remove smaller regional airports and ports from the top-level compliance category, easing onboarding for third-party contractors. Virtual town-hall sessions will be held on 6, 14 and 21 July to gather industry feedback. Submissions close on 31 July, after which Home Affairs will finalise a bill for introduction to Parliament later in 2026. Global mobility teams supporting defence, energy or transport clients should coordinate with security and legal colleagues to review the exposure draft. Any shift in reporting thresholds or foreign-ownership definitions could alter visa-sponsorship strategies, particularly where labour-agreement concessions depend on a project’s critical-infrastructure status. If enacted, the changes would represent the most significant rewrite of SOCI since the Pandemic-Era amendments of 2021, further embedding security compliance as an essential consideration in workforce-planning for infrastructure assignments.
