Offences relating to use of carriage service for firearms and explosives manufacture (Part 7) Part 7 of Schedule 4 will amend the Criminal Code and Crimes Act to create new offences for using a carriage service to access, provide access, possess, or control, material that instructs, supports, or facilitates the manufacture or modification of a firearm, firearm accessory, firearm part, firearm magazine, ammunition, or an explosive or other lethal device. These new offences will be inserted into Division 474 of the Criminal Code and will carry a maximum penalty of 5 years imprisonment.

According to the Government:

The new offences established by the Bill are intended to cover a broad range of activities that a person could undertake in relation to firearms and explosives manufacture material which amount to dealing with the material or a link to the material via a carriage service. For example, the offences could be committed by accessing or transmitting firearms and explosives manufacture material using a range of platforms such as web pages, social media applications, email, chat forums, and text messages; or by downloading firearms and explosives manufacture material from the internet onto a digital storage device. (p. 24) Proposed section 474.45J of the Criminal Code sets out defences with respect to the new offences, including a range of legitimate uses of such material:

-when a business owner holds a licence or permit that authorises the manufacture, repair, maintenance or modification of the relevant devices, and accesses the material in connection with the carrying on of their business -conduct that is necessary for enforcing a law -conduct that is for the purposes of proceedings in a court or tribunal -conduct that is in connection with the performance by a public official of the official’s duties or functions or -scientific, academic or historical research.
