When can I have sex? What are the ages of consent in South Australia? Who cannot have sex with me?
What you need to know – in brief
It is never okay for any person to have sex with another person who is under 16.
For 16 year olds, another person who is 16 can have sex with you if you both agree to it.
If you are 17 or older, you can legally have sex with another person who is 17 or older so long as you both agree to it, but it is a serious crime for a person in a position of care or authority over you to have sex with you and the carer/supervisor can be charged.
If you feel unsure about someone’s age, it is always good to check.
When the law is broken, the police and courts may get involved.
There are services that can help you with how you’re feeling, safe sex, relationships, sexual abuse and the law.
What you need to know – in full
15 year old Maddy (not her real name) from South Australia sent a Lawmail to us asking is it against the law to have sex with my 19 year old girlfriend?
We advised Maddy that she is under the general age of consent for sex in South Australia (there are multiple ages of consent in South Australia and they apply equally to straight, gay, lesbian, bisexual sex and to people of all genders). She was told that even if she is willing to have sex with her girlfriend, it is still against the law for her girlfriend to have sex with her. Her girlfriend (not Maddy) could face a serious criminal charge, jail and be placed on the sex offender register. Maddy was also told that once she turns 17, she and her girlfriend can have sex legally in South Australia. Maddy was also given referrals to local services she could contact if she wanted to discuss safe sex.
In South Australia, there are a few different ages of consent imposing limitations on when and with who you can have sex. They exist to balance your human right to choose when and with who you will have sex and your human right, as a child or young person, to be protected from sexual abuse, particularly by adults. If you have been sexually abused, the experience and impact of that will be different for you than for anyone else, but whatever your reaction, it is a normal response to an extreme situation. You are not to blame. Please also see our South Australia pages on Sexual Assault and Child Abuse.
On this page, sex means when a penis is fully or partially inside another person’s vagina, anus or mouth AND ALSO when another part of a person’s body (e.g. finger, tongue) or an object is fully or partially inside another person’s vagina or anus.
So, sex here means sexual penetration – we are not talking here about kissing or touching that does not involve sexual penetration. We are also not talking here about the additional laws applying to sex that is filmed, photographed or distributed online or by phone (for that see our South Australia Sexting page).
The age of consent is the age at which the law says you can agree (consent) to have sex.
If you are under the age of consent, the law says that you cannot legally agree to have sex. So even if you say yes to sex, a person who has sex with you can be charged with a serious criminal offence, jailed and placed on the sex offender register.
In South Australia, there are a few different ages of consent imposing limitations on when and with who you can have sex, explained below.
- When you are under 16 years old, no one is allowed to have sex with you. (A person who had sex with a child under 17 has committed serious crimes, called rape and sexual penetration of a child, and can be charged, jailed and placed on the sex offender register).
- When you are 16 years old, you can legally have sex with another person who is 16 years old if you both agree to it. (A person who had sex with a 16 year old outside of these limited situations has committed serious crimes, called rape and sexual penetration of a child, and can be charged, jailed and placed on the sex offender register unless the person honestly believed that you were 17 or older).
- When you are 17 years old, you can legally have sex with another person who is 17 or older so long as you both agree to it.
- While you are under 18, however, it is also a serious criminal offence for someone who is caring for you, supervising you or has authority over you, like a teacher, sports coach, youth worker, counsellor, foster carer, religious instructor, health professional, police officer or employer to have sex with you. They can be charged, jailed and placed on the sex offender register.
- No member of your family is allowed to have sex with you. (A person who had sex with a child or young person who is a member of their family has committed a serious crime, called incest and possibly also rape and sexual penetration of a child, and can be charged, jailed and placed on the sex offender register).
If you are confused about the law (it is confusing so don’t worry), please send us a Lawmail.
Agree (consent) means free agreement to sex. It is more than merely submitting to sex. A person does not freely agree to sex when: (1) submitting because of force or fear; OR (2) they are being restrained against their wishes; OR (3) they are asleep, unconscious or severely affected by alcohol or another drug; OR (4) mistakenly believing that the sex is for medical or hygienic purposes. There are other ways too in which the law says that a person has not freely agreed to sex. Lawmail can advise you if you have any concerns about free agreement (consent) during sex.
Family means your parent, your grandparent, brother, sister, half- brother or half-sister.
Sex offender register: All adults who have committed a sex crime involving a child are automatically included in a register of sex offenders. Child sex offenders under the age of 18 years may also be included in the register by a court order. Registered sex offenders are required to keep the police informed about their personal details and whereabouts. They are also required to report the names and ages of children with whom they live or have regular contact. Registered sex offenders are also prevented from engaging in child-related employment.
Deciding to have sex with someone is a big step. The decision is up to you. If you feel pressured to have sex, or if you’re not sure, you can say no. The other person must respect your choice. If they physically try to have sex with you without your agreement, they may be committing a crime.
If you are thinking about having sex, you need to be aware of the risks that are involved which include getting a sexually transmissible infection (STI) like chlamydia and blood borne viruses like HIV. Another risk is unplanned pregnancy.
