9 In my opinion, the passage in the direction set out above infringes s 106D in that it conveys to the jury the suggestion that it is unsafe to convict on the uncorroborated evidence of K because children are classified by the law as unreliable witnesses in that they do fantasise. It should be emphasised, however, that s 106D does not in any respect lessen the need for a warning to be given in relation to an individual child witness where it is necessary to avoid any perceptible risk of a miscarriage of justice arising from the particular circumstances of the case. If a long period of time has elapsed since the alleged offence, or if the credibility of the witness is affected, for example, by inconsistencies in his or her evidence, those matters should be drawn to the attention of the jury. The prohibition in the section is directed to warning juries against suggesting in any way that it is unsafe to convict on the evidence of a child because children constitute a special category of suspect witnesses - see generally Longman's case per Brennan, Dawson and Toohey JJ at 85-86 and R v FAR [1996] 2 Qd R 49, per Fitzgerald P at 58-59 and Davies JA at 61.
