What Does “Legal Age of Consent” Actually Mean?
The age of consent is the minimum age when someone can legally agree to sexual activity under Australian law, as defined by the Australian Institute of Family Studies.
But here’s what most people don’t understand:
It’s Not Just About Age
Even if both people are above the age of consent, sexual activity might still be illegal if:
- There’s a position of authority (teacher, coach, boss)
- Coercion or force is involved
- One person is significantly intoxicated
- Family relationships exist (always prohibited)
Common Myth Busting
Myth: “If they’re 16, anything goes”
Reality: Position of authority and other factors still apply
Myth: “Parents can give permission”
Reality: Parents cannot consent on behalf of their children
Myth: “It’s only illegal if someone complains”
Reality: Police can prosecute even without complaints

Close-in-Age Exceptions Explained
What Are Romeo & Juliet Laws?
These laws recognise that teenagers close in age might engage in sexual activity and shouldn’t face the same penalties as adults who exploit children.
How They Work
Typical Structure:
- 2-year age gap maximum
- Both parties must be above minimum age (usually 12-14)
- No position of authority can exist
- Genuine relationship must exist (not exploitation)
State Variations
Different states have different rules:
- Most generous: Victoria (2-year gap, minimum age 10)
- Most restrictive: South Australia (limited exceptions)
- Special cases: NT has fewer exceptions than other states
Position of Authority: The Hidden Danger
What Counts as Position of Authority?
Educational Settings:
- Teachers and students
- Tutors and pupils
- University lecturers and students
- School counsellors and students
Employment:
- Bosses and employees
- Supervisors and workers
- Mentors and trainees
Care Relationships:
- Foster carers and children
- Youth workers and clients
- Counsellors and patients
- Religious leaders and congregation members
Sports and Recreation:
- Coaches and athletes
- Team managers and players
- Instructors and students
Why These Laws Exist
Position of authority laws recognise that power imbalances prevent true consent.
Even if someone is above the age of consent, they cannot freely consent when there’s a power imbalance.
Real-World Impact
Position of authority laws can result in serious criminal charges even when both parties are above the general age of consent. Teachers, coaches, and employers face particular risks in these situations.
Age Limits
Most states extend position of authority protections until:
- Age 18 for most relationships
- Age 21 for some care relationships
- No age limit for family relationships
Legal Penalties: What’s at Stake
Criminal Charges
Common Charges:
- Sexual intercourse with a minor
- Indecent assault
- Statutory rape
- Grooming offences
- Child exploitation
Prison Sentences by State

| Aggravated | 16 years | 25 years | 20 years | 25 years | 25 years | 25 years | 19 years | 25 years |

Frequently Asked Questions
1. What if both people are under the age of consent?
Most states have close-in-age exceptions that protect teenagers who are close in age. However, the specific rules vary by state, and there are still minimum ages (usually 12-14) below which no sexual activity is legal.
2. Can parents give permission for their teen to have sex?
No. Parents cannot consent to sexual activity on behalf of their children. The age of consent laws exist independently of parental permission.
3. What happens if we started dating when both under 18, but now one is over?
Generally, if the relationship was legal when it started, it remains legal. However, position of authority rules might still apply in certain situations.
4. Are the laws different for same-sex relationships?
No. Age of consent laws apply equally to all sexual relationships regardless of gender or sexual orientation.
5. What about online relationships and sexting?
Online grooming laws apply the same age restrictions. Sexting involving anyone under 18 can constitute child pornography offences, even if the person took the images themselves.
6. Do these laws apply if we travel between states?
You must follow the laws of the state you’re in. However, some federal offences may apply if you travel specifically to circumvent age of consent laws.
7. What if the “victim” doesn’t want to press charges?
Police and prosecutors can proceed with charges even if the alleged victim doesn’t want to press charges. Sexual offence cases are considered crimes against the state, not just against individuals.
8. How do I report suspected statutory rape?
Contact your local police on 000 for emergencies, or the non-emergency line for your state. You can also contact child protection services. Many states have anonymous reporting options.
9. What’s the difference between statutory rape and regular rape?
Statutory rape refers to sexual activity with someone under the age of consent, regardless of whether force was used. Regular rape involves lack of consent, regardless of age.
10. Can teachers ever have relationships with students?
Not while the student is under 18 and enrolled at the school. Even after the student turns 18, many schools have professional conduct policies that prohibit such relationships.
