The present case is one that may properly be described either as a failure to advise (i.e., an omission) or as a negligent misstatement of fact (i.e., a positive act). Strictly, the complaint is one of negligent omission, namely, failure to do various things, including failure to draw the attention of M.M.C. and the members of the Manildra Group (including the respondents) to the requirement to pay withholding tax on M.M.C.'s interest payments to the first respondent. However, there are cases where, when information is being imparted, the failure to draw attention to some particular matter is, for practical purposes, the same as a positive statement as to that matter. That was the situation in Shaddock & Associates Pty. Ltd. v. Parramatta City Council [No. 1] [55] . And it would seem that that is also the present case, for, in a context in which the appellant was providing professional accountancy services on the basis that withholding tax was not payable, the failure to draw attention to the requirement that it be paid was, for all practical purposes, equivalent to a positive statement that it was not payable. When the case is approached on that basis it is clear that, in substance, the cause of complaint is the act of providing the professional accountancy services on an incorrect basis. The same is true if the matter is approached as an omission, for the omission takes its significance from that same act of providing those services. That act is in no way comparable to an act, such as that in Diamond and in The "Albaforth" , which passes across space to be completed in some place different from the place where it was initiated. The act of providing accountancy services was an act complete in itself, or, if not complete in itself, one that was initiated and completed in the one place. That place was Missouri. The fundamental significance of that simple fact is not diminished merely because it may be possible, for the purpose of legal classification, to treat that act as equivalent to a statement that was received or acted upon in Australia.
