The NPWS manages the largest and most diverse collection of historic coastal defence sites in Australia. These include:
- dozens of gun batteries and emplacements
- defensive works such as ditches, military roads, barbed wire entanglements and forts
- support facilities including barracks and amenities
- many other purpose-built or adapted military structures.
Some of these sites date to the first half of the 19th century. They are among the oldest buildings and structures in their localities. Many have been registered by the National Trust or have been classified as nationally significant on the Register of the National Estate.
