Piper Alderman strengthens national projects, infrastructure and construction team with partner in Perth


Piper Alderman is delighted to announce the appointment of Katie Winterbourne as a new partner in the firm’s Perth office, effective from November 20, 2023.

With over 25 years providing strategic commercial legal advice within the resources, energy and infrastructure sectors, Katie’s arrival follows the recent hire of Perth based partner Nick Foulkes and reflects the firm’s ongoing growth and investment in its national  projects, infrastructure and construction practice.

Katie advises on project planning, development, operations and closure and negotiates the associated commercial and stakeholder documents.  She assists clients to obtain and maintain project tenure and regulatory approvals, including working with State Agreements. Katie also assists with complex transactions to buy and sell resources, energy and infrastructure assets, drafting transaction documents and undertaking target due diligence.

Commenting on her decision to join Piper Alderman, Katie said:

“I am thrilled to become a part of Piper Alderman’s established projects, infrastructure and construction practice and I am excited to contribute to the growth of this practice in Western Australia. Western Australia supports a vibrant economy with many resources, energy transition and agribusiness projects on the horizon, which must be developed in a sustainable manner.”

Prior to founding Lantegy Legal, Katie was a partner at a global law firm, where she was an integral part of the resources and energy practice based in Perth. Additionally, she contributed her legal acumen as an in-house lawyer at BHP for more than four years, supporting the nickel mining operations and business development.

Katie has an enduring interest in environmental and natural resources policy, demonstrated through her work on various legal projects in Calgary, Canada, where she advised the Chair of the Alberta Environmental Appeals Board on hearings related to contaminated land and water resource allocation and the City of Calgary on water trading within the Bow and Elbow catchments.  Early in her career, Katie also assisted the WA Government with one of its reviews into WA water legislation.

She is acknowledged in The Best Lawyers in Australia across multiple practice areas including Planning and Environment Law, Water Law, Mining Law and Natural Resources Law.

Managing Partner, Tony Britten-Jones commented on Katie’s appointment:

“We are very excited to be welcoming Katie to our team. Her wealth of experience and deep understanding of the legal landscape in Western Australia will undoubtedly enhance our capabilities.

While Piper Alderman is a national firm, our approach to expansion is about finding the best local people with local knowledge and supporting them to deliver industry-leading advice and services to clients.

Katie’s reputation as a distinguished lawyer in the field, coupled with her commitment to environmental matters, aligns perfectly with our values and goals. We look forward to her contributions and continued success at Piper Alderman.”

Head of Perth Office, Shane Entriken commented:

“Katie’s appointment strengthens our local expertise in an area that is growing and has been very strong for the firm nationally. By welcoming Katie to our team, we further reinforce our capabilities in the major projects space.”
