Cyberstalking in South Australia has been outlawed.
People who use computer technology to cause physical or mental harm face a maximum five-year jail term.
SA Attorney General Trevor Griffin said stalking was outlawed in 1994, and cyberstalking would now face a similar crackdown.
Under the proposed legislation, cyberstalking would involve the use of the Internet or other electronic communication to publish or transmit offensive material in a manner that would arouse apprehension or fear.
Griffin defined a cyberstalker as someone who sends e-mails to his or her victim, seeks to contact his or her victim through chatrooms, posts information about the victim on the Internet, or directs his or her victim to offensive or threatening Web sites.
