The Statutory framework for determining the land value
18Section 6A(1) of the Valuation Act identifies the meaning of 'land value' as follows:
6A Land value
(1) The land value of land is the capital sum which the fee-simple of the land might be expected to realise if offered for sale on such reasonable terms and conditions as a bona-fide seller would require, assuming that the improvements, if any, thereon or appertaining thereto, other than land improvements, and made or acquired by the owner or the owner's predecessor in title had not been made.
(2) Notwithstanding anything in subsection (1), in determining the land value of any land it shall be assumed that:
(a) the land may be used, or may continue to be used, for any purpose for which it was being used, or for which it could be used, at the date to which the valuation relates, and
(b) such improvements may be continued or made on the land as may be required in order to enable the land to continue to be so used,
but nothing in this subsection prevents regard being had, in determining that value, to any other purpose for which the land may be used on the assumption that the improvements, if any, other than land improvements, referred to in subsection (1) had not been made.
(3) Notwithstanding anything in subsection (1), in determining the land value of any land, being land in relation to which, at the date to which the valuation relates, there was a water right:
(a) the land value shall include the value of the right, and
(b) it shall be assumed that the right shall continue to apply in relation to the land.
(4) For the purpose of determining the value of a water right, the value of any water secured by, or referable to, that right is to be ignored.
19The concept of "land improvements", referred to in s 6A(1), is defined in s 4(1) of the Valuation Act to mean:
Land improvements means:
(a) the clearing of land by the removal or thinning out of timber, scrub or other vegetable growths,
(b) the picking up and removal of stone,
(c)the improvement of soil fertility or the structure of soil,
(d) the restoration or improvement of land surface by excavation, filling, grading or levelling, not being works of irrigation or conservation,
(d1) without limiting paragraph (d), any excavation, filling, grading or levelling of land (otherwise than for the purpose of irrigation or conservation) that is associated with:
(i) the erection of any building or structure, or
(ii) the carrying out of any work, or
(iii) the operations of any mine or extractive industry,
(e)the reclamation of land by draining or filling together with any retaining walls or other works appurtenant to the reclamation, and
(f) underground drains.
20Also relevant in this appeal is The Threatened Species Conservation (Biodiversity Banking) Regulation 2008 - Regulation 11 (Regulation 11) which provides:
11 Land excluded from being designated as biobank site
(1) Land is not to be designated as a biobank site by a biobanking agreement if:
(a) the Minister is of the opinion that any previous, current or proposed use of the land proposed to be designated as a biobank site is inconsistent with biodiversity conservation or will prevent management actions from being carried out on the land or prevent the purpose of those actions from being achieved, or
(b) the Minister is of the opinion that any previous, current or proposed use of any land that is adjacent to or in the vicinity of the land proposed to be designated as a biobank site will prevent management actions from being carried out on the land proposed to be designated as a biobank site or prevent the purpose of those actions from being achieved, or
(c) the land is the subject of an offset (within the meaning of the Native Vegetation Regulation 2005) under a property vegetation plan approved under the Native Vegetation Act 2003, or
(d) the Minister is of the opinion that the land is already the subject of a requirement to carry out biodiversity conservation measures of an ongoing nature on the land under a condition of an approval or consent granted under Part 3A, 4 or 5 of the Environmental Planning and Assessment Act 1979 (this extends to any land that is the subject of a conservation agreement entered into under the National Parks and Wildlife Act 1974 for the purpose of compliance with such a condition), or
(e) the Minister is of the opinion that biodiversity conservation measures are already being carried out, or are required to be carried out, on the land under an offset arrangement made for the purpose of complying with requirements imposed by or under any Act (including the requirements of any authority granted by a public authority under any Act), or
(f) the land is reserved under Part 4 or Part 4A of the National Parks and Wildlife Act 1974, or
(g) the land is a flora reserve or special management zone within the meaning of the Forestry Act 2012 .
(2) Subclause (1) does not prevent other parts of a parcel of land (that do not fall within subclause (1) (a)-(g)) from being designated as a biobank site by a biobanking agreement.
(3) This clause has effect in relation to land at the time that any biobanking agreement in relation to that land is first entered into or proposed to be entered into. Accordingly, the fact that land designated as a biobank site by a biobanking agreement becomes, after the biobanking agreement is entered into, land excluded from being designated as a biobank site under this clause does not affect the validity of the biobanking agreement (or any subsequent variation of the agreement).
