Partnerships

Long-term, government-to-government partnerships are at the core of P4I’s approach, connecting Australian public sector expertise with the priorities of Southeast Asian counterparts. Through these partnerships, government agencies, regulators, utilities and infrastructure institutions share policy insight, technical experience and co-designed approaches. This model supports coordinated planning, strengthens institutional capability and helps address policy and investment bottlenecks to strengthen institutional alignment and improve investment readiness across the region.

P4I brings together expertise from across Australian agencies and institutions to support Southeast Asian governments in strengthening infrastructure planning and policy development. This cooperation forms part of Australia’s broader commitment to long-term, region-wide partnership.

How we work

Building on longstanding engagement across the region, P4I brings together Australian and Southeast Asian government counterparts, independent regulators, utilities and infrastructure operators to share technical and policy advice, and specific infrastructure investments advice. We collaborate with a wide range of other bilateral development partners and multilateral organisations.
P4I works with partners across transport, energy, telecommunications, and public investment management. Its approach is both top-down and bottom-up—supporting broader policy reforms while also addressing investment barriers faced by businesses and investors. By removing bottlenecks and improving infrastructure decision-making, P4I helps unlock new opportunities for investment, innovation, and sustainable growth across the region.
P4I supports government organisations and other institutions to develop partnerships that deliver real results for infrastructure development and investment in Southeast Asia. This tailored support enables partners to focus their resources and efforts on key priorities.
