The Department advertises all applications in the NT news. They will arrange the advertisement, but you will be responsible for the cost.
You will need to negotiate any access you might need to land with the landowner, prior to submitting your application. If you can't come to an access agreement with the landowner or leaseholder, you can apply for a permit which will allow you to enter land for pipeline route investigations.
If you require any further information, please contact the Department.
