Age of consent, peer sexual activity and mandatory reporting
Age of consent, peer sexual activity and mandatory reporting (Australia and Queensland)
Age of consent in Australia
The legal age of consent for sexual activity is:
- 16 years in:
- Australian Capital Territory
- New South Wales
- Northern Territory
- Queensland
- Victoria
- Western Australia
- 17 years in:
- South Australia
- Tasmania
A person below the legal age of consent cannot legally consent to sexual activity, even if they appear willing.
Consent assessment
Consent is not determined by age alone. Valid consent must be:
- Freely and voluntarily given
- Informed
- Ongoing
- Capable of being withdrawn at any time
Consent may be invalid where affected by:
- Threats
- Fear
- Coercion
- Grooming
- Emotional pressure
- Intoxication
- Unconsciousness
- Cognitive impairment
- Exploitation
- Significant developmental disparity
- Authority or power imbalance
Examples of relationships involving power imbalance include:
- Teacher–student
- Sports coach–athlete
- Employer–employee
- Faith leader–young person
- Residential care worker–resident
- Health practitioner–patient
- Carer–dependent young person
Clinical assessment should focus on whether the young person had genuine freedom and capacity to consent.
| Factor | Meaning | Examples | Why consent may be invalid |
|---|---|---|---|
| Threats | Direct or implied threats used to obtain sexual activity | – “If you don’t do this, I’ll hurt you” – Threatening to share intimate photos – Threatening self-harm, violence, homelessness, or deportation | Consent obtained through threat is not voluntary |
| Fear | Person agrees because they are frightened or intimidated | – Fear of violence – Fear of partner’s anger – Fear due to prior abuse – Child appears frozen, fearful, overly compliant | Fear can prevent free and genuine choice |
| Coercion | Manipulation, intimidation, or controlling behaviour undermining free choice | – Repeated pressure after saying “no” – Emotional blackmail – Controlling relationship dynamics – Using dependence on money/housing/drugs | Consent given under coercion is not freely given |
| Grooming | Building trust/dependency to facilitate exploitation or abuse | – Excessive gifts or attention – Encouraging secrecy – Sexualised messaging – Online grooming – Isolating child from supports | Grooming manipulates vulnerability and impairs genuine consent |
| Pressure | Social or emotional pressure influencing agreement | – “If you loved me, you would” – Peer pressure – Pressure to keep relationship – Feeling obligated after gifts | Person may agree despite not truly wanting sexual activity |
| Intoxication | Alcohol/drugs impairing judgement or awareness | – Severe alcohol intoxication – Drug intoxication – Confusion/slurred speech – Substance spiking | Person may lack capacity to understand or freely consent |
| Unconsciousness | Person unable to consciously participate or decide | – Passed out – Asleep – Sedated – Medically unconscious | An unconscious person cannot consent |
| Cognitive impairment or incapacity | Impaired ability to understand, weigh, or communicate decisions | – Intellectual disability – Dementia/delirium – Acute psychosis – Severe developmental delay | Person may lack decision-making capacity |
| Significant age difference | Major developmental or maturity gap | – Adult with young adolescent – Older teen with much younger child | Younger person may be vulnerable to influence/exploitation |
| Power imbalance | One person holds authority, influence, or control | – Teacher–student – Doctor–patient – Coach–athlete – Employer–employee – Carer–dependent person | Power disparity may undermine genuine freedom to refuse |
| Exploitation or abuse | Sexual activity involving manipulation, harm, or use of vulnerability | – Sex exchanged for money/drugs/accommodation – Child sexual abuse – Sharing images without consent – Domestic violence context | Exploitation invalidates genuine consent and may constitute abuse/offe |
Peer (“close-in-age”) sexual activity
Some states have close-in-age provisions for young people below the age of consent, but this varies significantly by jurisdiction.
Purpose
- Designed to avoid criminalising genuinely consensual peer relationships between adolescents.
- Aim to balance:
- protection from exploitation
- recognition of normal adolescent peer relationships
| State/Territory | Age of consent | Close-in-age provision |
|---|---|---|
| Queensland | 16 | No specific statutory close-in-age exemption described |
| New South Wales | 16 | Approx. ≤2-year age gap provision |
| Victoria | 16 | ≤2-year close-in-age exception |
| Western Australia | 16 | No specific close-in-age exemption |
| Northern Territory | 16 | No specific close-in-age exemption |
| Australian Capital Territory | 16 | No specific close-in-age exemption |
| South Australia | 17 | No specific close-in-age exemption |
| Tasmania | 17 | 15-year-old: up to 5-year gap; 12–15 years: up to 3-year gap |
Queensland
Queensland does not have a simple statutory “Romeo and Juliet” exemption automatically legalising sexual activity between minors close in age.
Importantly:
- Disclosure of consensual peer sexual activity between adolescents does not automatically require:
- mandatory reporting,
- police notification, or
- criminal investigation.
Clinical assessment should instead consider:
- safeguarding risk,
- developmental context,
- coercion,
- exploitation,
- significant harm,
- power imbalance,
- and protective factors.
Clinical safeguarding assessment
When assessing sexual activity between adolescents, clinicians should consider whether the activity was:
- Mutual
- Genuinely consensual
- Developmentally appropriate
- Free from:
- coercion,
- threats,
- fear,
- grooming,
- exploitation,
- abuse,
- intoxication,
- impaired capacity,
- or significant authority imbalance.
Assessment should also include:
- psychosocial context,
- home safety,
- emotional wellbeing,
- relationship dynamics,
- developmental maturity,
- cultural considerations,
- and parental protective capacity.
Examples
- 14–15-year-old in consensual peer relationship:
- May not require mandatory report if no safeguarding concerns
- Significant age disparity (e.g., 14-year-old with 30-year-old):
- Raises strong concerns regarding exploitation
- Likely requires child protection consultation/reporting
- Intellectual disability:
- Capacity and vulnerability must be carefully assessed
- Relationships with unequal cognitive or developmental power require heightened concern
Queensland mandatory reporting obligations
Under the Child Protection Act 1999 (Qld), doctors are mandatory reporters.
Relevant legislation
- Child Protection Act 1999 (Qld), s 13E
- Identifies doctors and registered nurses as mandatory reporters.
- A report to Child Safety is required where there is a reasonable suspicion that a child:
- has suffered,
- is suffering,
- or is at unacceptable risk of suffering
significant harm caused by:
- physical abuse, or
- sexual abuse,
and may not have a parent able and willing to protect them.
Key clinical point
Mandatory reporting is not triggered solely because:
- a young person is sexually active, or
- two adolescents close in age engage in consensual sexual activity.
The reporting threshold relates to:
- suspected significant harm,
- sexual abuse or exploitation,
- and concern regarding lack of parental protection.
If the relationship appears:
- genuinely mutual,
- developmentally similar,
- non-coercive,
- non-exploitative,
- and there are no broader safeguarding concerns,
then a mandatory Child Safety report may not be required solely on that basis. Careful documentation and ongoing review remain important.
Separate Queensland criminal reporting obligation
Queensland also has separate criminal legislation requiring reporting of certain sexual offences against children.
Under the Criminal Code Act 1899 (Qld):
- Adults must report certain sexual offences committed by another adult against a child unless there is a reasonable excuse.
For this legislation, a “child” includes:
- a person under 16 years, or
- a person under 18 years with an impairment of the mind.
Position of authority laws (Queensland)
Queensland introduced new “position of authority” sexual offence laws commencing 20 September 2025.
Under these provisions:
- it is unlawful for an adult in a position of care, supervision or authority to engage in sexual activity with a 16–17-year-old,
- even where the young person states they consented.
This may include:
- teachers,
- sports coaches,
- employers/supervisors,
- faith leaders,
- residential care workers,
- health practitioners,
- and carers.
The law recognises that dependency, trust and unequal power may impair genuine consent.
Red flags requiring escalation or reporting consideration
Features increasing concern include:
- Adult involved with child under 16
- Significant age disparity
- Grooming behaviours
- Coercion or threats
- Fear or inability to refuse
- Position of authority relationship
- Family violence
- Exploitation
- Cognitive impairment
- Intoxication affecting consent
- Unsafe home environment
- STI or pregnancy in a very young child
- Recurrent absconding or high-risk behaviour
