Environment Minister Tanya Plibersek plans to reject the $1.4 billion Toondah Harbour development due to environmental concerns.

The proposed site is near Brisbane, impacting Moreton Bay and rare wetlands.

Walker Group, the project's developer, seeks to address these concerns during a 10-day regulatory review period.

Expert Dr. Tony Matthews criticizes the original approval for development on protected wetland and recommends a more sensitive approach.

Local community and Redland City Council worry about the project's scale and environmental impact.

The situation has triggered a broader discussion on the need for stronger national environmental laws.

State Development Minister Grace Grace awaits the Walker Group's response to Plibersek's decision before commenting.
