The legal age of consent in Australia is one of the most commonly misunderstood areas of criminal law. Many people search for answers to questions like:
- What is the age of consent in Australia?
- Is there a legal age gap for relationships?
- Can someone under 17 legally consent to sex?
The laws vary depending on the state or territory, so it’s important to understand how they apply where you live.

Age of Consent in South Australia
In South Australia, the legal age of consent is 17 years old.
This means:
- It is a criminal offence to engage in sexual activity with someone under 17, even if they consent.
- The law is strict, and there are no exceptions for relationships where both people agree.
- The law is in place to protect minors from exploitation and harm.
How Does South Australia Compare to Other States?
In most other Australian states and territories, the age of consent is 16.
Tasmania also has an age of consent of 17 years old, making it the only other state with this distinction.
This difference is critical for people moving between states or involved in cross-border relationships.
Is There a Legal Age Gap or ‘Romeo and Juliet’ Law?
Some states have age-gap defences (often called “Romeo and Juliet laws”) that protect young people in consensual relationships where both are close in age.
In South Australia:
- There is no formal close-in-age defence.
- However, section 49(3) of the Criminal Law Consolidation Act 1935 allows a limited defence.
- This applies if the accused was over 16 years old and honestly and reasonably believed the other person was 17 or older.
- This defence only works if the belief was reasonable based on the circumstances.
Legal Consequences of Breaching Age of Consent Laws
Engaging in sexual conduct with someone under the age of consent in South Australia can result in:
- Criminal charges, even if both parties consent.
- Potential penalties including imprisonment.
- A permanent criminal record, which can have significant long-term consequences.
