While the age of consent is 16 in the majority of jurisdictions, it is 17 in South Australia and Tasmania. This applies to penetrative sexual intercourse, both heterosexual and homosexual, and to sexual acts that fall short of penetration.
In South Australia, this defence is limited to the situation where both the 'victim' and the 'offender' are aged 16. In most other states an age difference of up to two years is allowed under
Romeo and Juliette laws; in South Australia there is no such loophole. In this respect, the age of consent laws in South Australia are more stringent than in the rest of the country.
