31 Sections 76 to 76B of the EPA Act identify the three categories of development (development permissible without consent, development permissible only with consent, and prohibited development) by reference to the provisions of environmental planning instruments. The Kiama LEP 1996, SEPP 21, and SEPP 36 are environmental planning instruments and thus capable of regulating development in accordance with ss 76 to 76B. Section 36 of the EPA Act also applies (containing a general presumption that higher order instruments prevail to the extent of any inconsistency unless otherwise provided and subject to the capacity for any later instrument to amend an earlier instrument to provide for the way in which an inconsistency between them is to be resolved).
32 The provisions of, and policy disclosed by, these planning instruments, do not support the respondent's arguments. SEPP 21 commenced on 24 April 1992 and has been amended since. It does not prohibit any development permitted under another instrument. The key provisions of SEPP 21 (cll 8 to 10) require development consent to be obtained for caravan parks, permit subdivision for lease purposes, and impose obligations on the consent authority to consider certain matters in determining whether to grant consent. Accordingly, and for example, the requirement for development consent in SEPP 21 would prevail over any instrument permitting such development without consent. Similarly, the capacity to subdivide caravan parks in cl 9 of SEPP 21 would prevail over any prohibition on such subdivision in another instrument. Clause 7 of SEPP 21 performs an important function in this context. It ensures that, whether or not other instruments define caravan park or camping ground and howsoever those terms may be defined, the provisions of SEPP 21 will operate. Accordingly, consent will be required for any such development. Any such land will be able to be subdivided for lease purposes. A consent authority will have to consider the matters nominated in SEPP 21 when deciding whether to grant consent.
