We recommend that property owners mark powerlines to make them more visible and help prevent contact with them. We have a range of overhead warning markers you can use where low level flying operations take place or where machinery is frequently operated.
Refer to our powerline marker flyer (PDF 1.8 mb) for more information.
Aircraft warning markers
You are responsible for organising the installation of powerline markers where regular low-level flying operations take place on your property. To arrange for markers to be installed, complete our Powerline Hazard Identifier Application Form (PDF 139.5 kb).
Aerial markers should only be installed, maintained or removed by us.
Choose marker colours that are highly visible and contrast with background colours. Different colours can be used for different directions and backgrounds (e.g. white and orange alternated).
As the person requesting planned low-level flying activities, requesting markers is your responsibility under AS 3891– 2008 Air navigation - Cables and their supporting structures - Marking and safety requirements. The pilot or pilot’s delegate will need to be satisfied by these markers before starting low-level operations.
Who's responsible for what
- The person requesting planned low-level flying operations (e.g. the landowner) is responsible for requesting installation of markers
- The pilot or pilot’s delegate should be satisfied as to the need for and effectiveness of markers before starting low-level flying operations
- Aerial markers should only be installed, maintained or removed by us.
