145 As to the general impact on a viewer (assumed to be a passenger and thus free to observe without the necessity of concentration on driving responsibilities) from a vehicle travelling westward along Wentworth Avenue, the curve approaching the proposed bridge site and the vegetation on the left of the road will limit the period during which the bridge will be in view. It is unlikely that such a viewer will see much of the wetlands until after they have passed the bridge site and come abreast the wetlands immediately to both sides of the road. This is because the roadside vegetation will limit viewing to anything other than glimpses through its breaks.
146 After they pass any bridge, it ceases to be part of their immediate contextual reference for the wetlands.
147 The consequence of the foregoing, in my view, is that this westward travelling, wetland informed passenger would not have such visual appreciation of the wetlands, as they would have during such transit, impacted in any appreciably negative fashion.
148 As to the general impact on a viewer (similarly assumed to be a passenger and thus free to observe without the necessity of concentration on driving responsibilities) from a vehicle travelling eastward along Wentworth Avenue, they will see the bridge at a greater separation. This viewer will have arrived at a viewing point by vehicle travelling generally westward along Wentworth Ave or in one having debouched from Southern Cross Drive, turning left into Wentworth Ave. Any difference in view appreciation as a consequence of the mode of arrival would be, in my assessment, de minimus.
149 This hypothetical, informed viewer will see a bridge at several hundred metres distance. The more immediate views to the wetlands on either side of the road will be partially obscured by the roadside vegetation which will limit oblique viewing. For this viewer to obtain a reasonable and properly informed appreciation of the wetlands, I am satisfied that they would need to turn to observe directly to the north or south to look along the reaches of the portion of the wetlands opened up to them through the trees. Doing so, of course, would render the sight of a bridge marginal and peripheral at most.
150 Having observed the wetlands in this fashion, this hypothetical, informed viewer might turn to look toward the east and will see a bridge - however, it will no longer be in the context of the wetlands. If there were some fleeting adverse contextual impression, it would certainly not likely to be sufficient (absent some adverse impact from the particular design of the bridge), in itself, to warrant refusal of an appropriate bridge structure.
151 As to the general impact on viewers from The Lakes golf course, a bridge will be seen against the backdrop of the local high point and may be screened to some extent - depending on the viewing location - by vegetation both on their own course and on the applicant's course. The direction of play on the south-playing fairway is oblique and not directly toward a bridge at the proposed site. The direction of play on the north-playing fairway is both oblique and away from a bridge at the proposed site.
152 However, these golfers will be the persons most likely to have, after the golf course's own players, some sustained view of a bridge across the wetlands. In this context, a well-designed structure (which added interest to the panorama and was set against a natural backdrop including the local high point) would not provide an adverse contextual appreciation of the wetlands. Indeed, if of an interesting design, a bridge might well draw their eyes in a positive fashion - thus enhancing an appreciation of the interlying wetlands. I do not consider that a well-designed bridge structure would cause unacceptable impacts, in this planning context, from this vantage point.
153 As to the general impact on viewers from the fairways of the golf course itself, Ms Plate concluded:
The proposal would facilitate use and appreciation of the Botany wetlands by users of the golf course.
154 In this regard, I accept her conclusion - indeed, as discussed further below in the context of the proposed signage, those using any bridge linking the two portions of the golf course will obtain a significantly enhanced appreciation of the wetlands and their setting. As a consequence, far from being a potential negative, this aspect of the bridge is a positive benefit in promoting understanding or appreciation of the values of the wetlands.
155 Being satisfied that an observer aware of the significance of the Botany wetlands would not find any significant adverse impact, aesthetically or in any heritage context, it follows that no observer who was less well informed would find any adverse impact. As well, to the extent that there might be some marginal adverse impact, in my assessment, this is more than offset by the positive benefits of the appreciation of the wetlands in their context by future users of a bridge.
156 For completeness, I do not consider that any significant visual impact, in any context of the visual catchment of the wetlands or otherwise, arises from the rear of any property in Bay Street (to the east of the proposed bridge site) and I was certainly not asked to inspect the outlook from the rear on any of these properties. No resident in this vicinity made any objection to the proposal.
157 Finally, although not specifically put as an entirely abstract context absent any possible viewer, as there is clearly no physical impact on the wetlands from a properly and competently constructed bridge and ancillary structure nor any location from which there is an observable significant adverse impact (and, for one group of observers, a significantly enhanced appreciation of the wetlands), I am satisfied that there cannot be some theoretical adverse impact on the heritage or aesthetic values of the wetlands.
158 It therefore follows from the foregoing that I am satisfied that, for any observer who is aware of the heritage significance of the Botany wetlands, some appropriately minimally intrusive bridge at the proposed site would not adversely impact, to any relevant degree, on the heritage significance (and the appreciation of that significance) of the Botany wetlands.
