Avro 652A Anson aircraft

Greetings all from Adelaide South Australia. I am hoping there is some one out there that can help with a query that I have re Avro Anson aircraft and whether the aircraft that were built for Australia and the R.A.A.F. were actually flown before being crated for shipment to Australia. I ask this as information that I have is that these aircraft went to the RAF first before being sent down under any help will be gratefully received
