UDIA WA Committees & Working Groups
In 2023, along with a new Purpose, Vision, and Mission, the UDIA WA Council endorsed a revised governance structure to ensure strategic alignment and a focus on driving outcomes. Two new Strategic Committees have been formed and these are supported by six Operational Committees, a multiple-disciplinary Expert Pool, and Working Groups.
UDIA WA five policy-focused committees (which comprise our Advocacy & Thought Leadership Strategic Committee, and Infill Development & Precincts, Masterplanned Communities, Infrastructure, and Environment & Climate Action Operational Committees) assist in leading the planning, implementation and delivery of UDIA WA’s policy and advocacy agenda and help identify and address strategic opportunities and challenges faced by the urban development industry.
We also have three committees (our Education, Connection & Excellence Strategic Committee, and Professional Development and Community & Consumer Conversations Operational Committees) focused on helping us to maximise the value we deliver to our members and ensure continued growth.

UDIA WA’s Reconciliation Action Plan
UDIA WA’s REFLECT Reconciliation Action Plan (RAP) represents our commitment to take real action to support reconciliation in Australia.
Formally endorsed by Reconciliation Australia, our RAP forms part of a network of more than 3,000 corporate, government, and not-for-profit organisations that have made a formal commitment to reconciliation.
It has been developed with guidance from our RAP Working Group, over three years of listening, learning, and engaging with Aboriginal stakeholders and the wider development industry.
We strongly believe in providing leadership to the broader urban development industry in respect to reconciliation and more meaningful engagement with the Traditional Owners and Custodians of the lands on which we and our members operate.
Our RAP actions are focused on building a strong foundation to progress our reconciliation journey in a meaningful way.
