The Australian government's attempt to stem the flow of junk e-mail has been passed into law by the country's parliament.
But the legislation, passed last week, has come under fire from opposition politicians who believe a wide range of exemptions in the anti-spam laws favour certain interest groups.
Under the new legislation, spammers can be fined A$1.1 million (about HK$6.3 million) for each day that messages are sent.
The law also bans the sending of commercial e-mails unless there is consent from the recipient or the e-mails are sent as part of an existing business relationship.
The new anti-spamming law could provide a model for Hong Kong, where the government is considering legislation in response to pressure from the local IT industry and the Office of the Telecommunications Authority (Ofta).
The Australian legislation will be enforced by the Australian Communications Authority (ACA), a government regulator.
