This pressure occurs when there are significant changes to the physical structure, or composition, of beaches.

This can occur with coastal building developments and changes that occur with the addition of jetties and groins.

Dredging actions and vegetation clearing can also cause the composition of sediments around beaches to change.

  What we are doing:

  • We are monitoring vulnerable beach sites for signs of potential impact, as well as researching areas that may be vulnerable to modification.
  • We provide advice at the planning stage of development approvals to control the impacts of structures like jetties and groins and to assess the impacts on beaches from activities like dredging.

  What you can do:

  • Local Authorities can contact DBCA for advice on specific proposals.
  • Let others in your community know about the potential impact of beach modification.
