Easements generally give someone the right to access and use land while the legal title or ownership of the land remains with its owner. An easement does not grant ownership of the land. For Crown land, this means that a range of third parties can use the land for a variety of activities, while the State of New South Wales continues to own the land.
Easements are generally used to secure rights of access and rights for use of the land for utilities and infrastructure such as electricity lines, water supply lines, sewer pipes, bridges, drainage, and walking paths.
You will need to apply for a release of easement if you intend to terminate the easement agreement.
