DECISION
25 In addressing the question of whether there is an existing use of land, it is necessary first to identify, at least in general terms, the area of land one is concerned with, so that one can proceed to ascertain just what are the activities and physical features relied on as amounting to such a use. However, a determination that there is such an existing use of land does not of itself determine either (a) "the area actually and physically used" within s.107(2)(b) of the EPA Act, or (b) the extent of "the land on which the existing use was carried out" within cl.42(1) of the EPA Regulation. If determination of those limits is required, then in my opinion that is a further exercise which can only be carried out after one has identified the use.
26 It appears that the primary judge did not undertake this as a separate exercise, and the declaration she made could be regarded as ambiguous. It defined an area on a plan, thereby suggesting it was specifying the area in category (a) above, or possibly the area in category (b) above; but the order does not clearly state this. As I understood it, it was agreed by both parties that in fact the primary judge intended to indicate the area referred to in (a) above, that is, the area actually and physically used, and I will proceed on that basis. In those circumstances, it was not strictly correct for the judge not to address squarely the question of the area actually and physically used, after determining what the existing use was. Whether or not this involved any error in the result is a question I will return to.
27 Turning to ground 2, on the question of characterisation of use, I accept Mr. Craig's submission that the definition of existing use in s.106 means that the first question is whether there was use of land immediately before the coming into effect of SREP23 which SREP23 would have the effect of prohibiting as being a "large marina" as defined in SREP23. In that sense, it is necessary to approach the matter in the light of the definition, and to give retrospective effect to the definition to that extent.
28 However, in my opinion that does not necessarily mean that one stops there. For example, suppose the relevant prohibition was against use for "heavy industry", and suppose that the existing use was one type of heavy industry, say metal manufacturing. In those circumstances, one would find that this use was a use for heavy industry, and so would be prohibited; but this would not necessarily mean that the existing use should be characterised in terms of "heavy industry" rather than metal manufacturing. If one gave the use the wider characterisation, that would mean that the land could later be used for the manufacture of chemicals, for example, without development consent; and I do not think that would be in accordance with the intention of the existing use provisions: cf. Banool at 146.
29 So the first question is whether there was use of this land as a "large marina" as defined. The Macquarie dictionary relevantly defines "berth" to mean "room for a vessel to moor at a dock or ride at anchor"; and it is not disputed that each of the 72 swing moorings is a berth. Further, it is clear that the 29 berths and 72 swing moorings were used as part of one enterprise. Accordingly, there was a use of the land for a boat storage facility, with over 30 berths and support facilities; and so, subject to the appellant's point concerning the status of Sydney Harbour as a public waterway, there was use of the land as a "large marina" as defined.
30 In effect, Mr. Preston submitted that this should be regarded as a boat storage facility with only 29 berths: it was necessary to disregard the use of 72 swing moorings, since it was wrong to say that a public waterway was used for the purpose of a marina. Although use in conjunction with the marina was authorised by the Waterways Authority, Mr. Preston submitted that this was consistent with and did not detract from the status of the relevant waters as a public waterway, and the area was correctly considered as used as a public waterway, and not as a marina or part of a marina.
31 In my opinion, it must be kept in mind that the question of use, and its relevance to town planning prohibitions, is a separate question from authorisation from the owner of land or from a person empowered as a matter of title to authorise use of land. If a public waterway is in fact used as part of a marina, this may overcome a town planning prohibition from continuing that use; but this says nothing about whether that use is authorised as a matter of title.
32 As a matter of town planning, if RBM did not have the benefit of an existing use, and if an injunction was sought against it on the basis that its use of 79 swing moorings in conjunction with 29 fixed berths meant that it was conducting a large marina, I do not believe it could defend that claim on the basis that the 79 swing moorings had to be disregarded, because the only use recognised for the waters they occupied was use as a public waterway. Even in relation to public roads, there could be uses in addition to the use as a public road, for example where a restaurant is given a licence to place tables and chairs on a footpath, or an advertiser is given a licence to place advertising signs. In my opinion, the status of the waters of Sydney Harbour as a public waterway does not mean that the swing moorings cannot be regarded as being used for the purposes of a marina.
33 Accordingly, in my opinion there is no doubt that the existing use can be characterised as use as a boat storage facility which contains more than 30 berths and associated support facilities. However, there is some question as to whether the use should be described as also including a shop and restaurant. In my opinion, that depends on whether the conduct of the shop and restaurant should be considered as sufficiently integrated into the operation of the marina.
34 The primary judge held that the shop and restaurant were not "independent and unrelated uses", but rather were "facilities which are associated with and support the boat storage structures". However, in so doing she may have placed some weight on the definition in SREP23; and in my opinion, at that stage of the enquiry, that would be an error. It would then be a question whether such an error would vitiate the decision.
35 There were a number of factors supporting the view that the shop and restaurant were sufficiently integrated into the marina. They were located in the same building as the shore facilities of the marina, and in areas of the building subleased from RBM. I think judicial notice can be taken of the fact that businesses of this type are quite often associated with marinas. Furthermore, the businesses of the shop and restaurant and the business of the marina were and are, to some extent at least, mutually supportive. On the whole, I am not satisfied that the primary judge's decision was vitiated by her reference to the definition in SREP23, and in any event, I think it was the correct decision.
36 In the declaration she made, the primary judge expressed the use in terms of "large marina" as defined in SREP23. I think it preferable to express it more directly in ordinary English, to make it clear both what I believe to be the appropriate level of generality, and also the extent to which the use did and does in fact include "shops" and "restaurants", that is, one shop (milk bar) and one restaurant.
37 Next, there is the question of what was the area actually and physically used at the relevant time. Mr. Preston submitted that this area did not include the shop and the restaurant; but that matter is determined by my decision of the previous question. Mr. Preston also submitted that it was not proved that the area of the harbour claimed to be associated with the swing moorings was actually and physically used at the relevant time: the evidence did not show what use was made of what moorings at what times, or with what boats; and accordingly, it was not possible to infer that the whole of the area was in fact actually and physically used at the relevant time. Mr. Preston submitted that this question was not squarely addressed by the primary judge, and that the correct answer was that it could not be said that the whole of the area was actually and physically used.
38 Although the question was not addressed in precisely those terms, in my opinion that is in substance the question addressed by the primary judge, and in my opinion her decision was correct.
39 Where the use in question is of a kind that a large area is needed for the use, but only part of that area is physically occupied at any one time, it would be an error to say that only the particular part physically occupied at that time is actually and physically used at that time. The primary judge gave the example of a car park; and although it could be said that there is some difference from the present case in that, in the case of a car park, the occupier has a right to occupy a whole defined area, even if cars are parked in only part of that area at any time, I do not think this consideration makes the analogy inappropriate on the question of what area is actually and physically used. Another example would be a sports field used for athletics training, or as a cricket ground. In all these cases, actual and physical use of a large area may be established, even though the activities and physical features relied on do not at the relevant time occur over the whole area.
40 Here, although the evidence is not as clear as it might have been, it did in my opinion support a conclusion that all of the moorings were occupied for some substantial time during (say) the year prior to the relevant date, and also that a substantial number were occupied at any one time. It was not proved what size boats occupied what moorings, in order that one could know what size circle would have been swept by those boats; but it is relevant that the red line defining the area is drawn between the outer moorings themselves, not between the outer limits of the swept circles associated with the outer moorings. Furthermore, any internal gaps that might be created, if circles smaller than those postulated were adopted for particular moorings, would reasonably be regarded as being used for boat movements associated with the marina.
41 In my opinion, it would be the correct conclusion, on the evidence, that the whole of the area within the red line was actually and physically used for the purposes of the marina. Accordingly, this point also fails; and it follows that the appeal in substance fails.
42 In my opinion, there should be substituted for the declaration made by the primary judge, in order to clarify the effect of the declaration, the following declaration:
That the use of the land delineated in red on the plan attached to the order of the primary judge was immediately before 13 July 1990 and remains a use of that land for the purpose of a boat storage facility which contains more than 30 berths and associated support facilities and includes a shop (milk bar) and a restaurant, that the said area delineated in red was and continues to be actually and physically used for that purpose, and that such use constitutes a lawful "existing use" of that land within the meaning of s.106 of the Environmental Planning & Assessment Act 1979.
43 The orders I propose are:
1. Substitute for the declaration made by the primary judge the declaration set out in par.42.
2. Otherwise appeal dismissed.
3. Appellant to pay respondent's costs of the appeal.
44 SANTOW JA: I agree with Hodgson JA.
