3 An undercover police officer referred to in the trial and hereafter as "Sally" went to Allsop Park in Nimbin at about 9.30am on 21 April 2001. She subsequently spoke to a person, Cindy McHattan, and Sally followed her to where the appellant sat at a table in the park. Sally heard Ms McHattan say, "She wants 50 of H," and saw Ms McHattan hand to the appellant $50 which she, Sally, had previously given to her. The appellant then reached into a bag and took out a small clear plastic bag of white powder which was later analysed as heroin which she gave to Ms McHattan and Ms McHattan gave the bag to Sally who was sitting next to her.
4 On 2 May 2001, Sally again went to a bus stop near Allsop Park where she was approached by a man, Robert Tannock. After they had a conversation he went across the road into a newsagency from which he later emerged with the appellant. He returned to Sally and she gave him a $50 note. Sally saw him give the $50 note to the appellant who then gave to Mr Tannock a small plastic bag the contents of which were later analysed and found to be heroin.
5 On 10 May 2001, Sally again went to Nimbin where she arrived at Allsop Park at about 10.20am. She had a conversation with Melissa Pearson and then watched Ms Pearson enter the Freemason Hotel opposite the park. Shortly afterwards Ms Pearson came out of the hotel with the appellant. Sally saw the appellant remove something from her bag and hand it to Ms Pearson. Ms Pearson returned to Sally and gave her a small plastic bag containing what was later analysed and found to be heroin and Sally gave Ms Pearson $50. As Sally left the park she saw Ms Pearson walking in the direction of the Freeman Hotel.
6 In each instance Sally spoke to the intermediary (Cindy McHattan, Robert Tannock, Melissa Pearson), the intermediary spoke to the appellant, the appellant handed the heroin to the intermediary, and the intermediary handed the heroin to Sally in exchange for $50.
7 In the first and second instances, the intermediary was seen to hand the $50 to the appellant, whilst in the third instance, the intermediary was seen heading back to the hotel from which the appellant had emerged, to hand the heroin to the intermediary and to which she had returned, and the handing over of the $50 by the intermediary to the appellant was not observed.
8 It can be conceded that in the first two instances, Sally gave the $50 to the intermediary before the appellant gave the heroin to the intermediary to give to Sally whereas in the third instance, Sally gave the $50 to the intermediary after the appellant gave the heroin to the intermediary but this, in my opinion, is a minor difference of no significance.
