43 He then spoke to the local police Superintendent and asked the police to enforce compliance with the signs, and he subsequently saw police speaking to persons on the bridge, but they just continued to jump. On about 3 occasions, he saw a police boat patrolling under the bridge trying to round up people who had jumped from the bridge, but even this approach was unsuccessful. Since then, he has continued to observe people jumping from the bridge and the Council has continued to receive complaints about the practice. He has not taken any further action to enforce compliance with the signs since 1990 and claimed it is impossible for him to enforce the prohibition, which he agreed was, strictly speaking, a prohibition against diving, not against jumping.
44 The RTA conceded in its Answers to Interrogatories (Ex HH) that it was aware from 1 December 1993 that the riverbed levels under the bridge were continually altering and thereafter soundings were carried out from the bridge at approximately 3 monthly intervals. The Council admitted in its Defence to the Further Amended Statement of Claim that it was "aware of the fact persons had jumped and or dived from the bridge".
45 As long ago as 11 February 1993, the Council sent a facsimile to the RTA expressing the concern of the Council concerning "young persons jumping from the…bridge", adding the words "danger to boating", and "needs at least signs" (Ex U p 205). It was after this (in 1995) that the Council erected the "no diving" pictograms near each end of the bridge (Ex G3 p 127). It was about the same time that the wire in the railing was replaced as the earlier wiring was rusting thereby constituting a danger to young children.
46 I am satisfied on the evidence that the signs were not effective in the sense that large numbers of young people continued to jump, dive, do somersaults, etc from the bridge into the water. As already noted, when concerns were expressed by local residents and by the Council concerning pedestrian safety, officers of RTA visited the bridge in April 1998 when they observed persons jumping off the bridge, which they reported to the Regional Office. Subsequently plans have been prepared and funds approved for widening of the walkway and replacement of the post and rail fence with a fence containing vertical members in accordance with the '92 Austroads Standard.
47 An issue was raised by the defendants as to whether the plaintiff's spinal injury was in fact due to him striking his head on the bed of the estuary, but having regard to the manner in which he dived as described by him and confirmed by Mr Cunial, the fact that whilst in hospital he became aware of a lump on the back of his head, the report of Dr Matheson and that there is no evidence of any possible cause, I am satisfied that his spinal injury was most likely sustained when his head struck the estuary bed in the course of his dive.
48 The bridge forms part of Main Road III and was built with State funds by the Department of Main Roads, and by Minute of 16 September 1959 pursuant to s 25 of the Main Roads Act 1924 and with the concurrence of the Shires of Manning and Stroud (predecessors to the Great Lakes Council), the Commissioner for Main Roads (predecessor of the RTA) was authorised and directed to carry out the work of maintenance of the bridge. It was also agreed with Manning Shire Council that the latter would undertake the "caretaking" of the bridge at the Department's expense.
49 The ownership and classification of roads is now governed by the Roads Act 1993. Section 7(4) provides that the local council is the roads authority for all public roads within its area except freeways, Crown land and public roads for which some other public authority is declared by the regulations to be the roads authority. There is no evidence of any relevant regulation made in respect of this road and accordingly, I am satisfied that the Council is the "roads authority" in respect of this road subject to the Executive Council minute by virtue of which the RTA remains responsible for the maintenance of the bridge. Moreover, s 64 authorises the RTA to exercise the functions of a roads authority with respect to any classified road (which includes a public road) whether or not it is the roads authority for that road.
50 The relationship between the RTA and the Council in respect of the road including the bridge is further governed by the annual Block Grant Agreements whereby the RTA provides funding to the Council for the latter to carry out construction, maintenance and improvements on what are described in the agreements as "regional roads" and "traffic facilities" i.e. to improve the flow of traffic and road safety. Main Road III is specified as a "regional road" in the second schedule to the various Block Grant Agreements.
51 The RTA designed and built the bridge and pursuant to the Executive Council direction is responsible for its maintenance, and has financed works carried out by Council such as replacement of the wires on the bridge, the placement in about 1995 of the "no diving" pictograms, and has itself erected signs at each approach to the bridge prohibiting fishing and climbing on the bridge. It is presently about to engage in major reconstruction of the bridge's walkway.
52 The Council on the other hand is the roads authority and exercises day to day management of traffic over the bridge including pedestrian traffic. It erected the "no diving" pictograms in 1995 after making representations to the RTA and having their erection financed by the latter. It also made representations to the RTA in respect of the wiring on the bridge and subsequently carried out that work as subcontractor for the RTA. In addition, it has erected some signs such as the "no skateboarding" sign on its own initiative and at its own expense, and authorised local citizens to erect signs notifying local events. Its ranger, Mr Previtt also attempted to speak to persons jumping off the bridge some time ago.
53 For these reasons, I am satisfied the RTA is responsible for any matters related to the design or construction of the bridge including the erection of signs when the need or desirability for such signs arises from the design or construction of the bridge. On the other hand the Council is responsible for day to day management of the bridge, including the erection and enforcement of signs. In so far as it is relevant, I regard them as joint occupiers of the bridge.
54 I am satisfied that almost from the time of its construction and certainly for many years prior to the plaintiff's accident young, and not so young, persons were regularly using the railing and ledge of the bridge as launching pads for jumping and diving into the water below, particularly, but not limited to, during the summer holidays. The reason why jumping and diving off the bridge was so popular was in part due to the flat topped railing along the outside boundary of the bridge, and the ease of access to that railing by reason of the wooden cross members which provided steps up to the top railing.
55 Even if it was not anticipated prior to the construction of the bridge that it would be used in this way, it soon became apparent after its completion and foreseeable that the culture was likely to continue. Although the jumpers and divers entered the water in or near the main navigation channel, both the RTA and the Council were aware of the moving sands and variable depths underneath the water, and it was therefore reasonably foreseeable, and not far fetched or fanciful, that if the practice continued someone engaging in the activity was liable to suffer serious injury.
56 I say this notwithstanding the fact that no one had in fact been injured in nearly 50 years, because the risks should have been so apparent to the officers of both defendants with knowledge of the estuary bed that it was in effect "an accident waiting to happen". Subject to the provisions of the Civil Liability Act 2002 in respect of the Council, the defendants therefore owed a duty to those persons jumping or diving etc to take reasonable care to prevent injury to them. Their response was firstly, for Mr Previtt to speak to those jumpers but to no avail, and then to erect the "no diving" pictograms in 1995, but these seem to had virtually no effect as the practice continued apparently unabated.
57 The Council admits it knew the practice was continuing, the RTA does not; but I am satisfied that the practice was so widespread that, although the RTA did not have an office or depot in Forster/Tuncurry, it had maintenance and other crews working in the area and taking soundings of the water under the bridge, it must have known of the continuing practice as Mr Alexander virtually conceded at T 415. It certainly had direct knowledge after its representatives reported it in April 1998.
58 In my opinion, it was not sufficient to ignore the fact that the signs were being disregarded and it is necessary to consider what, if any, further steps should reasonably have been taken by way of further warning signs, modification of the bridge or otherwise, to prevent injury to persons such as the plaintiff; or to put it another way, the content of the duty of care.
59 I was referred to the Court of Appeal judgment in the 2 cases heard together of Wyong Shire Council v Vairy; Mulligan v Coffs Harbour City Council [2004] NSWCA 247, (hereinafter referred to as Vairy and Mulligan). The issue is those cases was isolated by Tobias JA at [20] as
"whether a public authority having the care, control and management of a natural aquatic area such as an ocean beach or tidal creek, will be in breach of its duty of care to an adult member of the public who voluntarily dives into water of unknown but variable depth where the authority has failed to erect a sign or signs warning of the danger of diving in those circumstances."
60 Here the plaintiff was not an adult and although no warning sign was in place, a prohibition sign was. Moreover in those cases, the plaintiff dived from natural features whereas here the plaintiff dived from an artificial structure erected by the RTA. Cases where the plaintiff dived from artificial structures erected by the defendant include Public Trustee v Sutherland Shire Council (1992) A Torts R #81-149 where breach of duty was established but the plaintiff failed on the issue of causation, and Inverell Municipal Council v Pennington (1993) 82 LGERA 268 where the plaintiff succeeded.
61 The fact that a risk is said to be "obvious" does not of it absolve a defendant from taking reasonable care but is only one of the circumstances which along with other circumstances needs to be taken into account: Woods v Multi-Sport Holdings Pty Ltd (2002) 208 CLR 460 at [45] per Gleeson CJ. Another relevant factor is the age and maturity of those likely to be at risk: Romeo v Conservation Commission (N.T.) (1998) 192 CLR 431 at [123], Vairy and Mulligan at [93].
62 In Vairy and Mulligan at [161] Tobias JA defined "obvious danger" for common law purposes as follows:
"Obvious" means that both the condition and the risk are apparent to and would be recognized by a reasonable man, in the position of the (plaintiff), exercising ordinary perception, intelligence and judgment."
