Our Executive

The Department of Primary Industries and Regional Development’s Executive team will leads the department across three operational pillars:

Sustainability and Biosecurity

This pillar includes our biosecurity, resource management, and operations and compliance functions. It is largely regulatory and market access focussed, helping ensure Western Australia maintains its enviable reputation as a producer of safe, sustainable and biosecure agricultural and aquatic products.

Industry and Economic Development

This pillar leads our work in research, development and innovation to boost the productivity, profitability and international competitiveness of our agriculture, fisheries and food sectors across the value chain, and grow the value and diversification of our regional economies.

Capability and Performance

This pillar supports all of our staff and ensures that we have the enabling strategy, resources and capability to deliver excellent public services.
