Overview

Breakwaters and training walls are large structures built of rock or concrete and positioned in the coastal zone. They are important for NSW coastal communities as they help to:

  • control where and how rivers meet the sea
  • create harbours, marinas and safe ports
  • protect some foreshores from erosion.

Many of these breakwaters are more than 100 years old and their design did not take into account how they would affect the environment.

This action aims to design breakwaters that deliver better outcomes for both the environment and people. It will include finding ways to make breakwaters:

  • friendly for marine life
  • safer for people with better access for fishing and recreation.
