From the archive: Tweed River Entrance Sand Bypass Project

Coastal adaptation can be hindered by real or perceived tradeoffs. The Tweed River Entrance Sand Bypass Project illustrates how engineered solutions can align with natural processes to balance multiple, often competing, coastal priorities to support both shoreline protection and environmental function.

At a glance

  • The Tweed River Entrance Sand Bypass Project (TRESBP) demonstrates the critical importance of managing coastal sediment to protect both infrastructure and natural assets.
  • After engineering works blocked natural sand flow from NSW to Queensland, Gold Coast beaches became vulnerable to severe erosion, impacting tourism and safety.
  • The TRESBP restored sediment movement using a permanent sand bypass system, reestablishing beach resilience and safe navigation.
  • This case study highlights how working with natural processes and long-term sediment management can reduce erosion risks, support economic activity, and adapt to climate change, offering a sustainable model for future coastal planning.
  • Note: this case study is from 2016. For more recent updates, check the Tweed bypass website for current activities.
