Understanding the Defence of Similar Age in NSW Sexual Offence Cases

In New South Wales, sexual offence laws are designed to protect young people from sexual exploitation and abuse. These laws are essential to ensure that children and teenagers are not subjected to harm by adults or older individuals. At the same time, the law recognises that consensual sexual activity between peers of similar age should not automatically result in criminal liability. To achieve this delicate balance, the defence of similar age exists.

The defence of similar age is a legal provision under the Crimes Act 1900 (NSW) that allows young people close in age to engage in consensual sexual activity without facing criminal charges, provided certain conditions are met. It is a safeguard designed to prevent the unnecessary criminalisation of adolescents who engage in normal sexual exploration with peers. This defence is particularly relevant in cases where the alleged victim is a minor, and the age difference between the accused and the alleged victim is relatively small.

Understanding how this defence operates, the offences it applies to, and the legal requirements is critical for anyone involved in a sexual offence matter in NSW.

Which Offences Qualify for the Defence?

The defence of similar age applies specifically to sexual offences involving minors or young people under special care. Under the Crimes Act 1900 (NSW), the defence can be raised in cases concerning:

• Sexual intercourse with a child aged 14–16 years (s 66C(3));
• Sexual touching of a child aged 10–16 years (s 66DB);
• Sexual acts with a child aged 10–16 years (s 66DD);
• Sexual intercourse with a young person under special care aged 16–18 years (s 73); and
• Sexual touching of a young person under special care aged 16–18 years (s 73A).

A key feature of this defence is that it does not depend on consent. This may seem counterintuitive, as sexual offences generally involve non-consensual conduct.  However, the defence focuses solely on the age relationship between the parties rather than whether consent was provided. By doing so, the law recognises that adolescents close in age may engage in consensual sexual activity as part of normal development.

For instance, if a 15-year-old engages in consensual sexual activity with a 16-year-old, the defence of similar age is designed to prevent prosecution for behaviour that is not exploitative or predatory. In contrast, the defence will not apply if the age difference exceeds the statutory limit or if the younger person is below the minimum age threshold.

Legal Criteria for the Defence

To successfully rely on the defence of similar age, two main legal criteria must be satisfied:

1. Age of the Alleged Victim

The alleged victim must be at least 14 years old at the time of the alleged offence. This minimum age threshold reflects the legal view that younger children cannot meaningfully consent to sexual activity and require protection from exploitation.

2. Age Difference Between Parties

The age difference between the accused and the alleged victim must not exceed two years. This requirement ensures that the defence only applies where both parties are close in age, minimising the risk of exploitation. For example, a 14-year-old and a 16-year-old would fall within the defence, whereas a 14-year-old and an 18-year-old would not.

It is important to note that the burden of proof rests with the prosecution once the defence is raised. The prosecution must prove beyond reasonable doubt that either:

• The alleged victim was younger than 14 years of age; or
• The age gap between the accused and the alleged victim exceeds two years.

The accused is not required to prove the defence; they only need to raise it as an issue in their case. This legal structure ensures that young people engaging in consensual activity with peers are not unfairly criminalised.

Purpose of the Defence

The defence of similar age was introduced to protect young people from unjust criminalisation while preserving safeguards against exploitation. By allowing this defence, the law acknowledges that sexual activity between peers close in age is generally consensual and developmentally normal.

For example, a 15-year-old engaging in sexual activity with a 16-year-old falls within the parameters of this defence, preventing prosecution for consensual acts that do not constitute predatory behaviour.

Enacted under section 80AG of the Crimes Act 1900 (NSW), the legislative intent is twofold:

• To safeguard minors from exploitation and sexual harm;
• To avoid unnecessarily penalising consensual peer activity, thereby maintaining fairness in the criminal justice system.

Differences Between Consent and the Defence of Similar Age

While consent is typically central in sexual offence cases, the defence of similar age functions independently. Its focus is on the age relationship between the parties rather than whether the sexual activity was voluntary.

Even when both individuals willingly engage in sexual activity, criminal liability can still arise if the age criteria are not met. In practice, this means the defence is concerned with establishing the ages of the accused and the alleged victim, rather than proving consent.

Understanding this distinction is essential for legal strategy, ensuring that arguments are correctly framed around age eligibility rather than the nature of consent.

Intersection With Other Defences

The defence of similar age can sometimes intersect with other legal defences:

• Mistaken belief in age – where the accused reasonably believed the victim was older;
• Duress or coercion defences – although rarely applied in peer cases; and
• Procedural or evidentiary defences – challenging evidence of age or consent.

Understanding how these defences interact is crucial for legal practitioners navigating complex sexual offence cases.

Aggravating Factors in Sexual Offence Cases

In sentencing sexual offences, certain factors can make the offence more serious and result in harsher penalties. One key factor is the abuse of authority or trust. This occurs when the offender uses their position of power over the victim, such as a teacher, coach, or caregiver. Under s 21A(2)(k) of the Crimes (Sentencing Procedure) Act, this is considered an aggravating factor. However, it does not apply if the offence already includes breach of trust as an element, such as under ss 61J(2)(e), 61KD(2)(b), or 61KF(2)(b) of the Crimes Act.

Courts also consider the nature of the relationship between the offender and the victim. Factors such as the victim’s age, disability, or dependency can make the victim more vulnerable, which the court may take into account when determining the seriousness of the offence.

The presence of aggravating factors can significantly influence sentencing outcomes. They may lead to higher penalties or affect the court’s discretion in deciding the appropriate sentence.

Other common aggravating factors include the use of violence or threats during the offence, offences that are pre-planned or repeated, and targeting victims known to be particularly vulnerable.

Conclusion

The defence of similar age is a critical feature of NSW sexual offence law, protecting adolescents from being criminalised for consensual sexual activity with peers. By applying to specific offences under the Crimes Act 1900 (NSW) and requiring that the alleged victim be at least 14 and within a two-year age gap, this defence ensures fairness in the legal system while continuing to protect vulnerable minors.

“The defence of similar age exists to ensure that young people engaging in consensual activity with peers of a close age are not unfairly criminalised. It’s about protecting normal adolescent development while maintaining safeguards for vulnerable minors.” – Jelena, Lamont Law
