Be careful in Victoria, there is some state legislation that enables charging for local council owned facilities, such as an NDB, when used for practice, even if you never land. The fees are enforceable.
The relevant Victorian State legislation is the
Aerodrome Landing Fees Act 2003. Under this legislation, one can be charged for simply making a training visual approach to a runway; doesn't necessarily have to be associated with the use of aerodrome based navaid facilities.
Airport operators can exercise discretion as to whether they wish to participate in and/or enforce the provisions of this Act.
