Partnerships for Infrastructure (P4I)
P4I is Australia’s flagship infrastructure development initiative in Southeast Asia. Funded though Australia’s development program, P4I works with eight Southeast Asian economies and ASEAN, supporting partners to manage and deliver new infrastructure worth over AUD 50 billion annually.
Southeast Asia is set to become the world’s fourth-largest economy by 2040. The development of quality infrastructure will be key to ensuring its growth is sustainable and inclusive. Closing the region’s estimated USD3 trillion infrastructure investment gap will require significant and sustained effort from Southeast Asian governments and their partners.
- 109 Australian organisations and 64 Southeast Asian counterpart agencies
supported to engage in direct technical and policy exchanges to advance priority infrastructure issues in the region. - 3000+
infrastructure professionals per year from across the region have built deeper technical and policy understanding in collaboration with Australian government and infrastructure professionals.

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.
