While pornography is legal in Australia, compared to other Western countries, Australia has historically had restrictive laws.
Prior to the invention of internet pornography, pornographic films were de facto illegal in all six states, with pornography only being legal in the territories.
Some extreme forms of pornography, such as pornography depicting children or animals, are illegal in Australia. Some other forms of pornography, such as BDSM pornography, are also technically illegal in Australia, but are widely available online.
