The legal age for consensual sex varies across Australian state and territory jurisdictions. The age of consent is 16 years of age in the Australian Capital Territory, New South Wales, Northern Territory, Victoria and Western Australia. In Tasmania and South Australia the age of consent is 17 years of age. Queensland is the only state that makes a distinction between different forms of sexual activity and the age of consent. In Queensland, the age of consent for anal sex (referred to as sodomy in legislation) is 18 years of age, while the age of consent for all other sexual behaviour (described as carnal knowledge) is 16 years of age.  

The Australian Sex Party advocates for nationally consistent age of consent laws and removing the distinction between different forms of sexual activity.
