New South Wales Consolidated RegulationsThe council should not prepare a draft local environmental plan which provides for development of land for the purpose of a new airport unless it is satisfied that:
(a) operation of the airport will not cause excessive noise intrusion to residential localities, and
(b) the land is substantially free from hazards to air navigation or can be made so without detrimental effects elsewhere, and
(c) the development will not have a detrimental economic effect on any other airports in the region.
