**3 On 18 June 1988 police arrested the applicant, David Reweti Croft, on a charge of trafficking in amphetamine. The evidence before the court was that undercover police officers, Angela King and Gary Attrill attended at premises in the Nepean Highway at Seaford that day purporting to be drug buyers. At the time there were a number of persons present at these premises. One of the undercover police officers was equipped with a recorder and listening device. It is asserted that whilst the police officers were at the premises the applicant arrived carrying a brown paper bag. The applicant was introduced to the undercover police officers as 'Geoff'. After some discussion, undercover police officer King went outside to a vehicle and returned with $10,000 which was handed over to the applicant in her presence. The applicant then handed over the paper bag to the undercover police officers. Upon that occurring, the premises were raided by police and all persons present were arrested. The contents of the brown paper bag were analysed by a forensic scientist and found to be powder which weighed 446.25 grams in total, of which 27.59 grams were found to be pure methylamphetamine.
