Agnes Water Drainage Study to improve development certainty

Published on 04 November 2025

Gladstone Regional Council has formally adopted the Agnes Water Drainage Study, delivering greater certainty for landowners and the building and development industry in the Agnes Water area.

Property owners now have access to up-to-date flood mapping that identifies whether their property is affected by flooding and if it is, the level of inundation and the impacts this may have on future development.

To assist the community and industry professionals, Council has prepared guidance material showing different development scenarios and the corresponding Council advice.

This guidance material along with the updated mapping can be found on Council’s website.

Where applicable, Council has proactively issued written advice for vacant properties that no longer fall within flood-affected areas, eliminating unnecessary regulatory burden for qualifying landowners.

The flood modelling data can be provided by Council’s Asset Planning team to qualified professionals through established data sharing agreements, ensuring consistent and reliable information across all assessments.

Council is continually refining the data to ensure the information provided to the community is accurate and any technical issues are resolved.

Gladstone Region Councillor Leanne Patrick said the adoption of the Agnes Water Drainage Study represents a commitment to evidence-based planning that balances community safety with practical development outcomes.

“We've worked to create processes that are both thorough and efficient,” Councillor Patrick said.

“This study provides our community with the certainty they deserve while maintaining appropriate flood risk management.”
