Sex and dating

For free and confidential legal advice about this topic, please contact us here.

There are generally no laws about when a young person can start dating another young person, but there are lots of laws around doing sexual acts with another person (including online sexual acts). If you think you are ready to start having a sexual relationship with someone, it is important to be aware of the laws that say how old you have to be, what a sexual act is, and what consent is.

Remember, it is NEVER okay for someone to force you to do something sexual without your permission, and you have the right to say NO at any time. For more information about sexual abuse take a look at this page.

Dating and relationships


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 which make grooming children under the age of 16 illegal. In Queensland, grooming may occur where a person (especially an adult) communicates with a young person who is under 16 years old so that they can sexually abuse that young person, or shows a young person who is under 16 sexual material (like a film or a picture). These laws can also apply to online relationships.

If you are worried about a relationship with an adult (including an online relationship), or communications you are receiving, you can contact us for free and confidential advice.

What is sex and sexual activity?


The law says that sexual intercourse (also known as ‘carnal knowledge’) is any penetration of a person’s vagina, genitalia or anus by a penis. 

A sexual act can include many different types of activities, such as:

  • sexual intercourse with another person
  • penetrating a vagina or anus with an object or another part of the body
  • penetrating a mouth with a penis
  • sexual touching – this includes touching over the clothes, touching under the clothes, handjobs and kissing
  • sexual acts that don’t involve touching – this can include masturbating in front of a person or encouraging a person to carry out a sexual act

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.

What is consent?

“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.

What does age of consent mean?


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 Queensland, the age of consent is 16. If you are 16 years old and above, you can legally engage in sexual acts with another person who is 16 years or older as long as you both agree to it. 

A person who is under the age of 12 can never consent to sexual activity.

In Queensland, there is a legal defence which can be raised when someone is charged with a crime for having sex with someone under 16. This defence can apply if a person has sex with someone aged 12-15 and they reasonably thought that person was aged 16 or older. However, raising a defence to a criminal charge can be complicated! 

It is also a crime for someone of any age to have sexual intercourse with a close family member (including a parent, sibling, grandparent, aunt or uncle) – 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 that makes you uncomfortable


If someone has done something without your permission or that has made you feel uncomfortable they may have sexually abused you. This is NEVER okay. For more information about sexual abuse take a look at this page.

What happens if someone breaks these laws?

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 against a child may be placed on the Child Protection Offender Register.

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 their behaviour has affected you, please also contact us.  

Thinking about having sex?


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: 

  • getting a sexually transmissible infection (STI) like chlamydia; 
  • getting a blood borne virus like HIV;
  • unplanned pregnancy; and
  • unplanned parenthood.

For information about how you can protect yourself from the risks of unsafe sex, you can see your GP or visit one of these websites:
