Which of the following laws or acts, formed in Australia, enforces prohibition against cyber stalking?

The Stalking Amendment Act (1999) was enacted in Australia, specifically in Queensland, to amend existing stalking legislation to encompass electronic forms of harassment and cyber stalking. It was one of the early legislative responses to the emerging problem of stalking conducted through digital and electronic means.

The Malicious Communications Act (1998) is a United Kingdom law, not an Australian act, and therefore does not apply to Australian jurisdiction.

There is no Australian law formally titled 'Anti-Cyber-Stalking law (1999)'; this is a fabricated option that does not correspond to any real legislation.

There is no Australian law formally titled 'Stalking by Electronic Communications Act (2001)'; this option does not correspond to any real enacted Australian legislation.
