State Environmental Planning Policy (Coastal Management) 2018 (Coastal Management SEPP) commenced on 3 April 2018.


The Coastal Management SEPP implements the objectives of the Coastal Management Act 2016 (the Act) from a land use planning perspective, by specifying how development proposals are to be assessed if they fall within the coastal zone.


The SEPP updated and consolidated these (now repealed) SEPPs into one integrated policy:

  • SEPP 14 (Coastal Wetlands)
  • SEPP 26 (Littoral Rainforests)
  • SEPP 71 (Coastal Protection), including clause 5.5. of the Standard Instrument – Principal Local Environmental Plan.


The SEPP promotes an integrated and coordinated approach to development assessment, with tailored development controls to ensure development proponents and consent authorities consider and address the most important issues for the coastal management area(s) their proposal falls within. The SEPP is supported by detailed mapping.


Local planning direction

A local planning direction for coastal management supports councils when developing and assessing planning proposals (to rezone land). This direction ensures that these strategic planning activities are consistent with the objectives of the Act and SEPP.


Planning proposals within the coastal zone need to be consistent with Coastal Management Programs (or Coastal Zone Management Plans that continue to have effect) for that area, or evidence obtained through similar processes or studies. This strategic approach will reduce the degree to which future land uses threaten important coastal and marine environmental assets, expose communities to coastal hazards or create other legacy issues that burden future generations.


Coastal zone mapping

The Act defines the NSW coastal zone, including for land use planning under the Environment Planning and Assessment Act 1979.


The Coastal Management SEPP includes mapping of the four coastal management areas that make up the coastal zone. With our Coastal Viewer you can view the coastal management areas down to the individual lot scale.

If using the ePlanning Spatial Viewer, the Coastal Management SEPP maps can be viewed alongside other relevant local and state planning controls.

Mapping updates

In December 2018, we made minor updates to the SEPP’s mapping tool in response to consultation with councils and public authorities to improve accuracy.


You can access the previous version of the Coastal Management SEPP maps (effective from 3 April – 16 December 2018).
