Sedgley-Perryman, Phil

National Manager Commercial

Phil has been a key team member in many high-profile, sensitive commercial matters and major projects for Commonwealth agencies. His work includes providing advice on key issues, governance arrangements, drafting contracts, designing and quality-assuring procurement projects and associated documentation, and advising on project planning to ensure that major projects across infrastructure, defence, information and communications technology (ICT) and property are brought in on time and on budget.

His experience working major projects for the Commonwealth includes advising on the development of the Western Sydney Airport, land acquisitions to support the construction of Melbourne Airport’s third runway, the Inland Rail Project, and the G20 and ASEAN events. Each of these projects has raised a wide range of novel and complex legal issues and required working closely with a number of Commonwealth agencies to achieve the Commonwealth’s objectives.

His governance experience includes the incorporation of WSA Co Limited, governance reviews for a number of other government business enterprises and providing advice on other complex financial and commercial arrangements, ranging from aircraft-leasing arrangements, the proposed acquisition by the Commonwealth of a large loan portfolio and taking security over assets to support contractual obligations.
