Project overview

Redland City Council is delivering a staged habitat restoration project along the upper tributaries of Tarradarrapin Creek within Judy Holt Bushland Reserve, Alexandra Hills. The project will treat priority invasive weeds and re-establish native vegetation to improve waterway health and habitat values over the long term.

The project includes staged treatment of invasive weeds across up to 20,000 square metres along the creek tributaries branching from William and Balmoral streets, followed by revegetation, maintenance, and annual reporting to the Department of the Environment, Tourism, Science and Innovation (DETSI).

Project details

Works are proposed to include:

  • staged weed treatment using low-impact methods suited to site conditions and public access constraints
  • revegetation with local native species to support riparian recovery and habitat improvement
  • follow-up maintenance over five years to consolidate outcomes and manage regrowth
  • monitoring and reporting on project delivery and performance throughout the project.

Why this project is being delivered

This project is being delivered as part of Redland City Council’s Make Good commitment following unlawful releases of treated wastewater containing elevated nutrient levels from the Capalaba Wastewater Treatment Plant (WWTP) to the Coolnwynpin/Tingalpa Creek catchment during maintenance works in 2025. These releases did not affect public health. Council regrets the 2025 incidents and the impacts they had on the environment and community.

Council is undertaking this restoration work in consultation with the Queensland environmental regulator, the Department of the Environment, Tourism, Science and Innovation (DETSI), to deliver a material and durable environmental improvement through restoration of riparian condition, reduction of erosion and sediment risks, and support for healthier downstream receiving environments. Through this project, Council is demonstrating its commitment to corrective action, environmental improvement, and transparent communication as delivery progresses.

Why Tarradarrapin Creek upper tributaries?

The selected site provides an opportunity to deliver practical, staged restoration with comparatively low delivery risk while still achieving a meaningful environmental benefit. The works build on previous restoration activity in the broader corridor and follow an upstream-to-downstream restoration approach to help reduce reinfestation risk.

Benefits for the community and environment

This project is expected to:

  • improve riparian vegetation structure and habitat values along Tarradarrapin Creek
  • reduce weed dominance and support long-term native species regeneration
  • support healthier downstream waterways and receiving environments.

What to expect during works

Works will be staged to reduce disturbance and manage safety within the creek corridor and nearby shared path areas. Temporary access changes, barriers or signage may be in place during active works. Council will seek to minimise impacts on nearby residents and visitors while restoration is underway.

Project updates

Council will provide updates on project timing, delivery milestones and site activities as works progress.
