A Serious Allegation Requires Serious Representation

Allegations involving sexual offences against children are among the most serious anyone can face. In Western Australia, the law treats these matters with the utmost gravity.

While the age of consent is 16, the law defines a child as anyone under 18. This means that even if a young person appears to consent, it can still be an offence to engage in sexual activity with them if they are under your care, supervision, or authority (see Children Aged 16–17 in Your Care or Authority below).

A conviction for a child sexual offence almost always results in imprisonment, and in some circumstances such as where the offence occurs during a home burglary, mandatory minimum sentences apply, even for first-time offenders.

At Perrella Legal, we know how devastating and complex these situations are. We provide discreet, experienced, and strategic representation to protect your rights, reputation, and future.

Understanding Child Sexual Offence Charges

Child sexual offences fall into several categories under both State and Commonwealth law, including:

  • Offences against children under 13;
  • Offences against children aged 13 to under 16;
  • Persistent sexual conduct with a child under 16;
  • Offences involving children aged 16–17 who are under your care or authority; and
  • Child sex tourism offences committed overseas by Australian citizens or residents.

A conviction can also result in registration on the Australian National Child Offender Register (ANCOR), leading to ongoing reporting obligations and, in some cases, lifelong supervision even after serving a sentence.

Offences Against Children Under 13

Possible charges include:

  • Sexual penetration of a child (maximum penalty is 20 years’ imprisonment);
  • Procuring or encouraging sexual behaviour (maximum penalty is 20 years’ imprisonment);
  • Indecent dealing, act, or recording (maximum penalty is 10 years’ imprisonment).

To prove the charge, the prosecution must show that the child was under 13, the conduct occurred, and that the accused committed the act. There is no mistake-of-age defence in this category. If the offence happens during an aggravated home burglary, mandatory imprisonment applies.

Offences Against Children Aged 13 to Under 16

Possible charges include::

  • Sexual penetration;
  • Procuring or inciting sexual behaviour;
  • Indecent dealing, act, or recording.

Maximum penalties:

  • Up to 14 years’ imprisonment, or 20 years if the child was under the accused’s authority;
  • Lesser penalties apply if the accused is under 18 and not in authority.

A limited “close-in-age” defence may apply where the accused reasonably believed the child was 16 or older and was no more than three years older than the child (but not if the child was under their care or supervision).

Persistent Sexual Conduct With a Child Under 16

This offence involves sexual acts on three or more different days and carries a maximum penalty of 20 years’ imprisonment.

Jurors do not need to agree on the exact acts or dates, but they must agree that persistent sexual conduct occurred within the alleged timeframe.

A limited close-in-age defence may apply in some cases.

Children Aged 16–17 in Your Care or Authority

These laws apply to sexual activity with older children who are under your care, supervision, or authority (for example, teachers, coaches, or employers).

Penalties include:

  • up to 10 years’ imprisonment for sexual penetration or procuring or inciting sexual behaviour
  • up to 5 years’ imprisonment for indecent dealing, or indecent recording.

Important points:

  • Consent is not a defence;
  • Belief about age is not a defence;
  • Lawful marriage is a complete defence.

Child Sex Tourism (Commonwealth Offences)

Australian citizens and residents can be prosecuted in Australia for sexual offences committed against children overseasPossible charges include:

  • Sexual intercourse or activity with a child outside Australia;
  • Persistent sexual abuse;
  • Grooming, procuring, or benefiting from such offences.

Defences may include:

  • Genuine (though not necessarily reasonable) belief the child was above the legal age; or
  • A valid, lawful marriage to the person at the time.

To be charged, the accused must have been an Australian citizen or resident when the offence occurred.

Frequently Asked Questions

In Western Australia, a child is anyone under 18 years of age. Even though the age of consent is 16, different offences apply depending on the child’s age and whether there was a relationship of care, supervision, or authority.

Child sexual offences fall into several parts, including:

  • Offences against children under 13;
  • Offences against children aged 13 to under 16;
  • Persistent sexual conduct with a child under 16;
  • Offences involving 16–17-year-olds in your care or authority; and

Child sex tourism (Commonwealth offences committed overseas).

Yes, in some situations. Consent is not a defence for many child sexual offences.
In particular, if the child is 16 or 17 but is under your care, supervision, or authority (for example as a teacher, coach, support worker, or employer), sexual activity can still be a criminal offence even if they agreed.

Offences involving children under 13 carry some of the most serious penalties in WA law:

  • Sexual penetration – up to 20 years;
  • Procuring/inciting sexual activity – up to 20 years;

Indecent dealing or recording – up to 10 years.
There is no mistake-of-age defence in this category.

In limited cases involving a child aged 13 to under 16, a defence may apply if:

  • The accused reasonably believed the child was 16 or older, and
  • The accused was no more than 3 years older than the child.
    This defence does not apply where the child was under the accused’s care, supervision, or authority.

This charge applies when sexual conduct is alleged to have occurred on three or more different days with a child under 16.
The maximum penalty is 20 years’ imprisonment.
The prosecution does not need to prove exact dates — only that the conduct happened repeatedly within the charged period.

Australian citizens and residents can be charged in Australia for child sexual offences committed overseas under Commonwealth child sex tourism laws.
These include allegations of sexual activity, grooming, procuring, or persistent abuse outside Australia.

Possibly. Conviction may result in registration on ANCOR (Australian National Child Offender Register).
This can involve long-term reporting obligations, restrictions, and in some cases supervision that continues well after any sentence is served.

Do not attend an interview or provide a statement without legal advice.
Anything said to police can be used as evidence later.
If police want to speak with you, contact Perrella Legal immediately so we can advise you before any questioning occurs.

Most child sexual offence allegations are dealt with in the District Court or Supreme Court, depending on the charge.
The matter usually starts in the Magistrates Court, then moves to a higher court for trial or sentencing.

Certain sexual offences committed during an aggravated home burglary carry mandatory minimum prison terms, even for first offenders.
This means the court must impose a prison sentence and cannot reduce it below the required minimum.

We provide discreet, strategic defence at every stage, including:

  • Advising before police interviews;
  • Analysing forensic, digital, and witness evidence;
  • Identifying defences and legal weaknesses;
  • Negotiating for withdrawal or reduction of charges; and
  • Representing you in court with confidentiality and care.
