Meaning of "major disturbance"
96 In Banjima People v Western Australia (No 2) [2013] FCA 868; 305 ALR 1, Barker J said (at [1467]):
Whether an earthwork is major would also depend, I consider, on the terrestrial context of the earthworks, for example a pit of this size in somewhere like Kings Park, Perth, in a nature reserve, would I think be considered a major earthwork, but in a vast area of remote country near a gravel road, probably not so.
97 Barker J considered whether the construction of gravel pits were works which caused major disturbance to the land. The pits were between 1 and 5 hectares in size and had a typical depth of 1 metre. His Honour concluded that the works were not sufficient in scale to constitute major earthworks when considered in the context of the land as a whole: at [1462] - [1468].
98 In Rubibi Community v State of Western Australia (No 7) [2006] FCA 459, Merkel J considered whether the construction of an oval within a reserve was a major earthwork. His Honour said (at [132]):
McMahon Oval is [a] reserve [that] includes an uncompleted sports oval which covers approximately 40% of the reserve. The oval has never been used as an oval. There was uncontested evidence that, in the course of creating the oval, the Shire carried out earthworks and installed drainage ditches and paths. There was also evidence that the whole of the reserve was traversed and disturbed by heavy earthmoving equipment during the creation of the oval and drainage ditches. A water storage tank was installed in the northern corner of the reserve. I undertook a site visit to McMahon Oval. I am satisfied that creation of the oval was a major earthwork ...
99 In Margarula v Northern Territory (2016) 257 FCR 226, Mansfield J said at [348] that while "major" could not qualify the word "disturbance" with any degree of precision, the use of the word "major" means that not all disturbances to the land will satisfy the definition. His Honour continued [349]):
The Explanatory Memorandum to the Native Title Bill 1993 (Cth) affords some assistance to the task of interpretation. It states that '[t]he definition of this term is intended to cover major or large scale works such as dams and weirs whose construction permanently and significantly disturbs or changes the land.' It goes on to note that 'the digging of a well, cultivating land to grow crops or establishing a walking trail in a national park would not constitute major earthworks.' I consider that accords with the natural meaning of the word major, and in the overall context it is also sensible generally to require a disturbance which has permanently and significantly disturbed or changed the land.
100 Mansfield J concluded that a sealed and contoured go-kart track with perimeter drainage works and occupying a significant space was clearly intended to exist indefinitely, contributing to a conclusion that it was a major earthwork in accordance with Merkel J's analysis in Rubibi: at [352] - [353].
101 As has already been observed, the construction of buildings such as the club rooms and the Sceale Bay Road each satisfy the definition of a "public work" because they are a "building" and a "road" respectively (see para (a)(i) and para (a)(ii) of the definition). The creation of those structures first occurred prior to 1975 and so had the effect of wholly extinguishing native title on the land on which they were situated. However, the Council did not suggest that the remainder of the 31 hectares of land on which the golf course is located should be considered as land upon which the road and club rooms must be taken to be situated because of the operation of s 251D of the NT Act. If I have misunderstood the Council's position in that respect I would conclude that s 251D does not have that operation on the facts. It has not been submitted that the whole of the golf course was incidental to or necessary for the construction and use of the road or the club rooms, nor does the evidence establish any such proposition.
102 The evidence in relation to the reintegration of the land on which the road once stood no doubt involved a major disturbance to the land, but native title on that parcel of land had already been wholly extinguished by virtue of the construction of the road prior to 1975. The same may be said of the later extensions to the club rooms and driveway incorporating the car park. That work occurred on land on which native title was wholly extinguished by virtue of the original construction of the building and car park prior to 1975. I not consider s 251D of the NT Act operates in a way that would include the remainder of the 31 hectares of land to be land upon which the works for the original construction or later expansion of the club rooms or car park is situated in any event.
103 It remains to determine whether the works for the establishment of the golf course caused a major disturbance to the land when considered as an integrated whole. In the analysis that follows I will focus first upon discrete features of the course (as that was the approach taken in the evidence and submissions), before analysing them together.
104 An important feature of the "major earthworks" definition is its focus on disturbance to the land itself, rather than upon the erection of fixtures or features upon or above the land's surface per se. The disturbance must be "to the land", and it must be "major".
105 I do not consider the planting of grass on the surface of land to constitute a major disturbance, even if the process of vegetation involves some amount of grading with heavy machinery in preparation for seeding, together with significant human effort. The same may be said of works involving the removal of vegetation. The removal of vegetation and the seeding of grass no doubt changed the aesthetics of the land, and significantly so. It also altered the uses to which the land could be put, transforming it from what the Council described as "scrubland" to a golfer's fairway. But a change to the appearance or amenity of the land's surface is not the test. It is necessary to have regard to the impact upon the land, both qualitatively and quantitatively.
106 In my evaluation the removal of vegetation or the reseeding of the land with grass did not cause "major" disturbance to the large tracts of land forming the fairways, notwithstanding their very large surface area. I consider that if the fairways were to be left unmaintained, they would soon enough revert to "scrubland" of the kind that existed before golf was first played there without the need for any remedial activity. It follows that the fairways, of themselves, do not constitute major earthworks and so are not public works.
107 Whether the land constituting the fairways must be taken to be included in land on which other public works are situated will be dealt with elsewhere in these reasons.
108 The applicant submitted that the activities undertaken on and relating to the golf course did not involve major disturbances to the land and instead constituted "modification and adaption of the parklands to allow golf to be played" occurring in an evolutionary way over a number of decades. It was submitted that the ongoing changes indicated that the features of the golf course referred to in the Council's affidavits could not have been intended to exist indefinitely. The impermanent nature of the changes was said to have been illustrated by yet further alterations to the golf course occurring after 1994 to the present day. Those further changes are evidenced by additional aerial photographs. It is unnecessary to describe them here.
109 In my view, it may reasonably be inferred that the works for the creation of the features of the golf course (and the later changes to those features) were subjectively intended to be indefinite at the time that they were undertaken. However, the fact that a significant number of features of the golf course were removed, relocated or altered from time to time is informative of the objective nature of the works and the degree to which they have impacted the land. The removal of mounds and scrapes is illustrative. Qualitatively speaking, the construction of scrapes and mounds involved the importation of fill for the purpose of raising the level of some parts of the ground to varying degrees. The evidence does not demonstrate that the construction of the mounds and scrapes involved disturbance of the land surface before fill (in the nature of imported slag or creek sand) was mounded upon it. Whilst the construction of those features no doubt involved the use of heavy machinery and the importation of fill, I am not satisfied that those activities constituted major earthworks when considered in the context of the golf course as a whole.
110 Whilst Mr Lane and Mr Rumbelow both referred to features of that kind being removed or replaced, it was not suggested that the land below the compacted mounds was significantly "disturbed" such as to require remedial works of any significance to be done to the underlying land when the man-made elevations were taken away. There is no evidence of remedial works in fact being undertaken so as to rehabilitate the land formerly covered by relocated scrapes or mounds, and it does not appear from the evidence that any such remedial work was required in fact. In my view, upon the removal of features of that kind, the land below was in its original state, as it had always been.
111 It is conceivable that the construction of mounds and scrapes may have caused some compaction in the underlying land, but there is insufficient evidence to support a finding that the compaction was "major" in its effect. I would draw that conclusion no matter what the height of each scrape.
112 The impact of the scrapes, tee-off points and mounds may also be considered having regard to the size of the footprint occupied by them relative to the surface area of the golf course as a whole. In the context of an area totalling 31 hectares, the areas on which the tee-off points and scrapes are situated are very small indeed. That is not to lose sight of the importance of considering the golf course as a singular "work", but if the scrapes and tee-off points are to be regarded as the most serious of all of the wounds on the land, I consider them to be few and far between.
113 Two mounded features require specific attention: the tee-off point and the scrape described earlier in these reasons at [74] and [70] respectively. Each of those features is significant in height relative to the usual height of the surface of the land. As has been said, the tee-off point is accessed by players using stairs to reach it. Notwithstanding their size relative to the other mounded features, I do not consider these features to be significant when considered in the context of the land as a whole and I do not consider the works for the construction of those two features to constitute major earthworks when considered both qualitatively and quantitatively.
114 As Mansfield J said in Margarula, by reference to the Explanatory Memoranda, the "major earthworks" definition is intended to cover large scale earthworks such as damns and weirs which permanently (or at least indefinitely) disturb the land. The evidence shows that the mounds are not immovable from the earth's surface and that they have in fact been removed or rebuilt in accordance with the Club's desires to change the configuration of the game from time to time. As has been said, neither their construction nor their removal involved major disturbance to the land in the requisite sense.
115 In the result, I am not satisfied that the construction of any one particular feature of the golf course referred to in the evidence and occurring after 31 October 1975 and before 1 January 1994 constitutes a major earthwork when considered separately. Accordingly, it is unnecessary to determine whether s 251D of the NT Act would operate to deem land to be included in the place where each of those asserted public works is situated. Nor do I consider those features described in the affidavits to constitute a major earthwork when considered together in the context of the golf course as an integrated whole.
116 I do not consider the works occurring prior to 31 October 1975 to differ in their nature to the works that occurred after that time. I am not satisfied that the original establishment of the golf course fulfils the definition of a "major earthwork" when considered as an integrated whole.
117 Whilst I am satisfied that much of the surface of the land has been disturbed by the evolutionary creation of the golf course over many decades, the evidence does not establish that there has been "major disturbance" to the land within the meaning of that phrase in the NT Act.
118 It follows that the answer to the Earthworks question is no.
