Section 308H Crimes Act | Unauthorised Access to Restricted Data


With recent advances in technology, there has been an increased focus on cybercrime and computer offences.

One of these offences is the offence of “unauthorised access to restricted data,” which is contained in s 308H of the Crimes Act.

This section states that you may be charged with a criminal offence if you cause unauthorised access to modification of restricted data in a computer.

To be found guilty of this offence, the prosecution must also prove that you knew the access or modification was unauthorised, yet you deliberately caused or allowed that modification.

This offence is known as a summary offence, which means that it will be heard in the Local Court in front of a magistrate.

The maximum penalty for this offence is 2 years imprisonment, however our expert lawyers can assist you in avoiding these harsh maximum penalties by presenting your case in a positive light and casting doubt on the prosecution case.
