I do not regard this as a case where it can be said that the jury could not have found that the plaintiff was not negligent even if the onus of proving this had rested upon him, but in any event I am not prepared to accept the broad proposition that there is never a duty of care owed by an occupier to a careless invitee or to an invitee who is aware of the dangerous condition of the premises to which he is invited. It is true that in South Australian Co. v. Richardson [1] , and in Bond v. South Australian Railways Commissioner [2] , Isaacs J. did use language to the effect that a plaintiff invitee must as part of his cause of action against the occupier negative a knowledge of the dangerous condition of the premises and negative negligence on his own part. In the earlier case when speaking of an invitor's alternative to making his premises safe, he said: "He has the alternative course open to him, by giving proper notice of the unusual danger, and, if he does, he cannot be held guilty of negligence with regard to safeguarding his visitor from damage. If actual notice of unusual danger is sufficient, it necessarily follows that the invitee's knowledge, however acquired, of that danger is equally sufficient to prevent him from complaining. The plaintiff's action for breach of this duty therefore includes as an essential that he, or the person he represents, was unacquainted with the danger" [3] . The decision in the case was, however, that notwithstanding the invitee's own evidence that he knew that there was some risk in using the defendant's premises, he might still recover, and so the Court there upheld the order of the Full Court of South Australia for the new trial of an action where at the trial judgment had been entered for the defendant because the plaintiff had knowledge or notice of the condition of the defendant's premises. Moreover, I prefer the judgment of Griffith C.J. to that of Isaacs J. and assuming that his Honour was referring to an unusual danger of which the occupier knew or ought to have known, I agree with the following statement of the Chief Justice: "With regard to the extent of the obligation, that is, the degree of care required of the inviter, I am of opinion that a person who provides a road or other means of access to, or egress from, his premises, and invites persons having business with him to make use of the means of access so provided, is bound as against them to take reasonable care that the means of access are reasonably safe for such use as they are invited to make of them in their apparent condition. The visitor, on his part, is bound to take reasonable care in the use which he makes of the means of access which he is invited to use. Since the obligation arises from the invitation, and is coextensive with it, it follows that, if the invitation itself is qualified by warning of danger, or knowledge of danger by the visitor, or otherwise, the obligation is qualified correspondingly. If, for instance, there is in a road which a person is invited to use any obvious defect, or defect known to him, of such a nature as to require special care in using it, the invitation is a qualified invitation to use the road with such special care as is required under such circumstances What degree of care on the part of persons using such a defective or dangerous road is reasonable in any particular case is a question of fact depending upon all the circumstances, which include their actual knowledge of the defect and the opportunity which they have of knowing it" [1] . In the same way in Bond v. South Australian Railways Commissioner [2] it was decided that an invitee's prior knowledge of a station platform from which he fell in the dark did not prevent him from recovering damages for the negligence of the defendant in omitting to light the station, and Knox C.J. and Starke J. said: "The knowledge of the appellant and any notice or warning given to him of the danger is relevant for the purpose of determining whether the respondent took reasonable care and whether the appellant chose to accept the risk or was guilty of contributory negligence, but these questions must be determined as matter of fact The error in the judgment in the Court below resides in the view that the duty of the respondent towards the appellant was discharged if the appellant knew or was informed of the danger, whereas the true rule is as already stated" [3] . Isaacs J. to the contrary said: "Where the invitee is, either by notice or knowledge cognizant of the danger he incurs, he cannot assert even an initial duty in the invitor to guard him against it" [4] . It seems to me that the actual decisions in these cases are certainly not adverse to the plaintiff here and that the reasoning of the Judges other than Isaacs J. does support his case. In Buckingham v. Luna Park (N.S.W.) Ltd. [5] , Jordan C.J. and Halse Rogers J. were of the opinion that where the invitee complains of injuries caused by an unusual danger, the burden of proof is upon him to establish that he had no knowledge or no adequate knowledge or warning of the danger. This accords with the views of Isaacs J. in the cases cited, but Davidson J. took a different view and I prefer his judgment.
