[5] Brady had previously held an authority to manage an inspection station which was revoked by the Department in 2002. In October of that year, he approached a mechanic named Kielly, whom he knew, asking if he wished to conduct an AIS. Kielly said he lacked the proper qualifications or certificate needed to do so; but, after consulting Moran, Brady arranged with him to obtain the required approval fraudulently. To do so, Brady completed an application to the Department on behalf of Kielly, registered a business name with the Department of Fair Trading, and prepared Kielly to undergo the necessary departmental examination set for authorised inspection operators. When Kielly began to express concerns about the operation, Brady mentioned it to Moran, who suggested setting up another inspection station JB Autos using the name of John Stanley Bailey, who was a former qualified operator who had died. This stratagem was carried out by means of false information supplied by Brady, who forged the signature of the deceased operator in order to obtain a false letter of authority and books of vehicle safety certificates from the Department. In addition, by using other documents, some of them false, Australia Post was induced to redirect mail to Brady's address, giving rise to the charge of the Commonwealth offence in count 6 of the indictment. In April 2003, a third inspection station was set up under the name Shale Mechanical, which the third applicant Shale operated after sitting and passing the departmental examination with the help of answers provided in advance by Moran to the examination questions.
