My Department does not have a specific policy regarding Ministerial use of private email addresses to conduct Government business. However, as stated in parliamentary responses reference Question No. 182 of 29 September 2018 and Question No. 198 of 13 December 2016, from late 2016 I have only used dedicated Department email addresses to communicate official Department business.
The Information Technology Unit of my Department regularly issue emails to Departmental staff reminding them that personally owned mobile devices and removable media devices are not permitted to connect to Departmental workstations and must not be used to store Departmental information.
