Premium Content Subscriber only In an odd turn of events, a defendant appearing in Biloela Magistrates Court thanked the Magistrate before receiving his punishment. Austin Wayne Potgieter pleaded guilty on Wednesday to one count of drug-driving. The court heard police were conducting static roadside breath and drug testing on Old Maryborough Rd, Gayndah, at 3.15pm on July 23 last year. The officers stopped Potgieter, driving a black Ford sedan, and he submitted to a saliva test which returned a positive reading. When police questioned Potgieter, a P-plater at the time, about any recent drug use he made full admissions to smoking cannabis a day earlier.
