In NSW, some forty-one years ago (1975), I was convicted of selling pot (I was 18). I was put away for 18 months with a non-parole of 12 months. I was released 12 months later. I also have a B&E 1 charge and car theft 2 charges. They were before the drugs charge.(1974) I recently got a National Police Clearance and these were on it. Is it possible for me to have them as spent convictions? I am currently in West Australia. but these offences happened in NSW.
