24 In my opinion, in those circumstances the evidence of what he said to the customs officer about such matters was highly probative in respect of the jury's task to decide the question whether they were persuaded beyond reasonable doubt that the appellant's evidence at trial was untrue. Any inconsistencies in the story from time to time were important, eg, as to where the documents were found; as was the admitted destruction of the scales, bearing in mind what had been said about them by the appellant. And so far as the appellant told a story at trial which was consistent with that given to Brightman, as was generally the case, it was important for the jury to see in what circumstances of questioning by the customs officer the story first emerged, including by reference to the content of the Incoming Passenger Card containing the statements that the appellant's intended address in Australia was at the Ambassador Hotel in Perth, that his usual occupation was "tour business" and that he was here as a tourist guide. It was important to see that the story about the acquisition of gems only emerged as the reason given originally for travelling to this country evaporated and the scales and plastic bags, in particular, were found in his luggage. To put the matter shortly, in my opinion, the first ground of appeal is entirely without merit.
