In general, there are no laws that say when a young person can start dating another person (but there are laws about doing sexual activity with another person, which we explain below).
However, there are laws that make it illegal for people (especially adults) to communicate with a young person who is under 17 years old so that they can sexually abuse that young person, or show a young person who is under 17 sexual material (like a film or a picture).
If you are worried about a relationship with an adult (including an online relationship), or communications you are receiving, please contact us for free and confidential advice.
The law says that sexual intercourse includes any penetration of a person’s vagina, labia majora or anus by any part of the body of another person or by any object, or any kind of oral sex.
A sexual act can include many different types of activities, such as:
Consent is required for any sexual act, not just those involving penetration.
There are also special laws that apply to recording a sexual activity with another person or sending or receiving sexual pictures or videos. For more information about these laws please see our pages on sexting and image-based abuse.
“Consent” means free and voluntary agreement. It is useful to think of consent as an enthusiastic yes! It is never okay for someone to force you to keep going if you want to stop. You can also change your mind or withdraw your consent at any time.
Consent is really important, and we recommend you check out our page on consent if you are thinking of having sex or doing something sexual with another person.
The age of consent is the age at which the law says a person can agree to do a sexual activity with another person. If you are under this age, the law says that you cannot legally consent to a sexual act, and any person who does a sexual act with you has broken the law.
In South Australia, the age of consent is 17. If you are 17 years old and above, you can legally engage in sexual acts with another person who is 17 years or older, as long as you both agree to it.
However, if the other person is in a position of authority over you (including a teacher, parent, carer, religious leader, doctor or employer) then you have to be at least 18 years old to consent to sexual activity with them.
In South Australia, consent to a sexual activity with a person who is between 16 and 17 years old can be a legal defence to a sexual crime if:
It is also a crime for persons of all ages to have sexual intercourse with a close family member (including a parent, sibling or grandparent) – even if there is consent.
If you are under 25 and you have any questions about these laws, please contact us for free and confidential legal advice here.
If someone has done something without your permission or something that has made you feel uncomfortable, this may be sexual abuse. This is NEVER okay. For more information about sexual abuse take a look at this page.

If someone is found guilty of breaking the laws around sex and consent, they may be convicted of a criminal offence. Sexual offences can carry serious penalties, and a person who has been convicted of a sexual offence may be placed on the Child Sex Offender Register in South Australia.
If you think you might have broken these laws, or you are worried about the police contacting you, you can contact us for free and confidential legal advice. If you think someone else might have broken these laws and them doing so has affected you, please also contact us.
Deciding to start a sexual relationship with someone, or have sex with them, is a big step. It’s important to make sure you feel ready. It’s normal to feel nervous and excited, and it can be helpful to talk to someone about how you are feeling before you decide.
If you feel pressured to do something sexual, or if you’re not sure if you want to, you can say NO. And if you say yes and then decide you no longer want to do something, you can stop at any time. The other person must respect your choice. If they do something sexual with you without your agreement, they are committing a serious crime.
If you are thinking about having sex, please be aware of the risks that are involved with unsafe or unprotected sex. These risks include:
