Indecent assault, explained simply

Indecent assault is a sexual offence: unwanted physical contact of a sexual nature, without consent. Unlike sexual assault or rape, it doesn't involve penetration — but the law still treats it as a serious breach of a person's body and dignity. It can happen anywhere: at home, in public, or where one person holds power over another, such as a workplace or school.

The basics

What indecent assault means

It happens when someone intentionally touches another person without their consent, and the touching is indecent — that is, it has a sexual character, judged against ordinary community standards. In plain terms, examples include unwanted sexual touching such as groping or a forced kiss, whether over or under clothing, or sexual touching done through force, threats or deception.

WHAT THE PROSECUTION MUST PROVE The contact was intentional Without consent Indecent / sexual in context No penetration is required — that's what sets it apart from sexual assault.
All three elements must be present. The line between indecent assault and the more serious sexual assault or rape offences is penetration — which indecent assault does not involve.
How it starts

How a charge usually starts

Police may lay a charge after:

  • A report or formal complaint from the person
  • CCTV or witness evidence
  • Recorded messages or admissions
  • Forensic or medical examination

Where the person involved is a child or otherwise vulnerable, extra protections and procedures apply.

In court

The court process

Less serious matters are heard in the Magistrates' or Local Court; indictable or aggravated cases go to the District, County or Supreme Court. The usual path:

  1. First appearance — a plea is entered.
  2. Evidence disclosure — from the prosecution to the defence.
  3. Hearing or trial — guilt is determined.
  4. Sentencing — based on the harm caused, the relationship, and any history.

Courts treat it more seriously where there was force, threats or coercion, where the person was under 16, or where the accused was in a position of authority or trust.

Defences

Which of these can apply depends entirely on the facts and the evidence — a criminal lawyer can tell you which, if any, fit your situation.

  • Consent (not valid if under the age of consent)
  • Reasonable, mistaken belief in consent
  • No indecent element — accidental or not sexual
  • No physical contact occurred
  • False accusation
  • Mental impairment
