The construction of Big Rocks Weir will increase water security for irrigators and the local community.

Project overview

The Big Rocks Weir project includes the construction of a new 10 gigalitre weir approximately 26 km north of Charters Towers in northern Queensland.

This additional water will support the development of up to 5,000 hectares of land for high-value agricultural purposes and will support improved agricultural output in the region. It will deliver water security to create opportunities to transition to high-value perennial crops such as table grapes, avocados and mangoes.

The ability for farmers to transition to high-value agriculture will increase the region’s annual agricultural revenue and support jobs growth.

Big Rocks Weir is expected to provide additional water storage in the Charters Towers region, supporting further development of irrigated agriculture and providing greater security of supply of water for Charters Towers.

The Big Rocks Weir detailed business case was completed in August 2020. Planning work, including environmental approval, is continuing.
