(2) Where a public authority:
(a) proposes to carry out development on land to which this clause applies, or
(b) proposes to grant approval or development consent in relation to development on land to which this clause applies, the public authority shall not carry out that development or grant the approval or development consent unless it has taken into account:
(c) the need to retain any bushland on the land;
(d) the effect of the proposed development on bushland zoned or reserved for public open space purposes and, in particular, on the erosion of soils, the siltation of streams and waterways and the spread of weeds and exotic plants within the bushland; and
(e) any other matters which, in the opinion of the approving or consent authority, are relevant to the protection and preservation of bushland zoned or reserved for public open space purposes."
The definition of Bushland as contained within SEPP No 19 is as follows:

4.4 Sydney Regional Environmental Plan No.23 - Sydney and Middle Harbours
The general aims of the is plan relevant to the application are
2(1)(c) to ensure that the Harbours and their foreshores are developed and promoted as a community asset, with due recognition being given to their role as a recreation and tourist focal point.
2(1) (e) to recognise, protect and enhance the natural, scenic, environmental, cultural and heritage qualities of the land to which this plan applies in future planning and development control.
2 (1) (j) to encourage an appreciation of the remaining natural foreshores around the Harbours
2(2)(e) in relation to the natural environment -
(i) to protect flora and fauna habitats, including wetland areas, in a manner that is consistent with their conservation value, while also recognising the validity of other uses of the foreshores and the waterway; and
2(2)(f) in relation to the visual environment -
(i) to protect and enhance the landscape and special scenic qualities of the Harbours; and
(ii) to ensure that adequate consideration is given to the visual impact of development; and
(iii) to preserve the natural foreshores of the Harbours and to ensure development does not detract from their natural character.
18 A consent authority must not consent to the carrying out of development unless it is satisfied that the proposed development is consistent with development of the land to which this plan applies in accordance with the objectives of this plan, and it has considered such of the following matters as are of relevance to the development-
(a) the appearance of the development from the waterway and the foreshores;
(b) whether the development will have an adverse effect on wetlands or flora and fauna habitats.
4.5 Development Control Plan 16- Dwelling Houses, Dual Occupancy and Boarding Houses in Residential Zones
DCP No.16 recognises the important environmental qualities of Castlecrag and reiterates the established character in the description of the desired future character of the locality.
In particular relevance to this site and proposed development the DCP requires:
2.2.2 Desired future Character of Castlecrag
1. Minimising the impact of the built environment by siting buildings sensitively, integrating the built form with the natural landscape, with the built form subsequent to the landscape and the predominance of natural landscaped areas on the site.
5. The predominance of a landscape of native vegetation and tree cover with informally landscaped private gardens merging into one another with minimal fences and walls, in particular to the street.
7. Retention of significant. trees and stands of significant natural vegetation. Plant locally indigenous trees and dense vegetation, both within the site and to the street frontage to maintain the natural landscape characteristics of the locality.
8. Avoiding loss of vegetation between and around dwellings to reduce the prominence of the built form when viewed from Middle Harbour and other vantages.
10. Minimising areas of driveways and paved surfaces at the street frontage and avoiding unbroken double garages facing the street.
12. Ensuring the preservation of remnant bushland and encouraging revegetation of foreshore properties to protect the visual amenity of the natural foreshore areas.
Section 3 Residential 2(a2) zone - Special Controls
In relation to the Residential 2(a2) - Scenic Protection area the DCP stipulates specific landscape and Scenic Amenity Controls.
The intent of this section is:
To ensure that the predominant landscape character of the foreshore and bushland area is maintained.
To protect land in environmentally sensitive and scenic protection areas from over development and to ensure development does not visually dominate the natural scenic qualities of the locality.
To minimize the effects of development on the ecology of the environmentally sensitive areas
To maintain and enhance the integrity of bushland through the use of native species in landscaping works.
To protect the bushland as a natural stabiliser of the soil surface.
Section 3.2 is concerned specifically with Foreshore Building Line.
The intent of the Section is:
To preserve and enhance the natural features and vegetation of the foreshore area for its scenic and ecological value and to ensure development does not detract from the natural character of these areas
To encourage the protection. and regeneration of land which forms an integral part of the foreshore setting and to maintain the amenity of foreshore properties.
Section 3.3 of the DCP is concerned with Bushfire, the intent of this Section is:
To minimise risk to person and property from bushfire.
To design for bushfire prevention so that the landscape and environmental qualities of the locality are maintained.
The specific performance criteria of this Section are-
A. Development of sites prone to bushfire hazard are to be designed and/or adopt measures which minimize potential hazard.
B. Sites are to be maintained to minimize bushfire hazard without unduly altering the natural qualities of the area.
C. Unencumbered access is to be provided for Bushfire purposes.
Section 4.01 Minimum Site Area
The intent of this section is to ensure allotments have sufficient area for the siting of development to achieve a good relationship to adjoining dwellings, provide adequate space for landscaped open space, drainage, parking, residential amenity and other services and be compatible with the general pattern of spacing of buildings in the area.
To achieve an efficient use of land for new housing.
The performance criteria relevant to this development are
i) Provide for usable open space and landscaping;
ii) Allow convenient vehicle access and parking;
iv) Have regard to topographical constraints and retention of significant trees;
v) Ensure development is compatible with the spacing and pattern of surrounding development
Section 4.03 Character, Design and Streetscape
The intent of this section relevant to this application is -
