Few things are more frightening or life-altering than being accused of sexual assault based on nothing more than one person’s word. At National Criminal Lawyers®, our sexual assault lawyers in Sydney frequently represent clients who suddenly find themselves the subject of allegations with no physical evidence, no witnesses, and no corroborating material, just a complainant’s account. These cases are often described as “he said, she said” matters, and they raise complex questions about credibility, consent, forensic gaps, and the limits of proof in criminal law.

In NSW, a person can be charged with sexual assault under s 61I of the Crimes Act 1900 (NSW) even where the only evidence is the complainant’s testimony. Sexual assault carries a maximum penalty of 14 years’ imprisonment and is viewed with utmost seriousness by the courts and police. But the fact that police lay a charge does not mean the evidence meets the standard required for conviction. The law demands proof beyond reasonable doubt, and courts apply strict principles when the case hinges entirely on uncorroborated allegations.

Understanding how these cases are investigated, prosecuted, tested at trial and sentenced is essential for anyone facing allegations in the absence of physical or forensic evidence.

National Criminal Lawyers has a rich record in successfully defending clients who have been accused of sexual assault charges.

Can You Be Convicted of Sexual Assault on Someone’s Word Alone?

Legally, yes, but only if the prosecution proves every element of the offence beyond reasonable doubt. The law does not require DNA, injuries, messages, admissions, or witnesses. However, where a case relies solely on the complainant’s account, courts apply a number of judicial safeguards and directions to ensure the accused receives a fair trial.

The starting point is that the prosecution must prove that sexual activity occurred, that it was without the complainant’s consent, and that the accused knew the complainant was not consenting or was reckless as to that fact. In “word-against-word” cases, these elements come under intense scrutiny, because the prosecution’s evidence rises and falls on the credibility of a single witness.

This is where NSW criminal law introduces important protections for the accused. Trial judges frequently give a Murray direction, derived from R v Murray (1987) 11 NSWLR 12, reminding jurors that if the prosecution case depends solely or substantially on the evidence of the complainant, and that evidence has weaknesses or inconsistencies, they must approach the evidence with caution. This direction recognises the real risk of wrongful conviction in cases lacking corroboration.

Depending on the circumstances, judges may also give a Longman warning from Longman v The Queen (1989) 168 CLR 79, particularly in historic allegations where delay has compromised the accused’s ability to respond. In such cases, jurors are warned that the passage of time may have caused significant forensic disadvantage, and that they should scrutinise the complainant’s evidence carefully.

These directions are not “loopholes”, they are essential safeguards embedded in NSW criminal law, acknowledging that uncorroborated evidence must be tested with special care to prevent miscarriages of justice.

What If There Is No Forensic Evidence?

The absence of physical evidence does not automatically defeat a prosecution, but it does influence how the case is assessed. JUDCOM research shows that lack of forensic evidence often increases the importance of credibility and reliability assessments. Courts examine:

• whether the complainant’s narrative is consistent across police statements, forensic interviews, and cross-examination
• whether the timing of the report makes the account more or less reliable
• whether the surrounding circumstances (messages, CCTV, witness observations) support or contradict the allegation

When the evidence is thin, jurors are reminded, often explicitly, that they cannot fill evidentiary gaps with speculation. A “possibly guilty” accused must still be acquitted unless the prosecution eliminates reasonable doubt.

Consent, Intoxication and Honest Mistake in Word-Against-Word Cases

Consent is central to sexual assault law in NSW. A key defence involves demonstrating that the accused reasonably believed the complainant was consenting. In cases involving alcohol, drugs or incomplete memories, the prosecution must still prove beyond reasonable doubt that the accused either knew the complainant was not consenting or was reckless. Defence lawyers often use surrounding circumstances, flirtation, mutual touching, prior communication, or behaviour observed by others, to show that any belief in consent was honestly held.

If the complainant’s memory is impaired, inconsistent, or reconstructed after the fact, courts must treat the evidence with caution. Where intoxication affects the complainant’s narrative, judges often reinforce to the jury that memory gaps or partial recollections require heightened scrutiny.

Bail for Sexual Assault Charges in NSW

Bail is a critical issue. Sexual assault is treated seriously under the Bail Act 2013 (NSW), but many clients successfully obtain bail, particularly when the case depends solely on allegations without physical evidence. Courts consider the strength of the prosecution case, and in “he said, she said” matters, the case strength may be assessed as weak, which increases the likelihood of bail being granted. Conditions often include non-contact orders, curfews, or restrictions on alcohol use.

Having a specialist sexual assault bail lawyer present submissions early can prevent unnecessary remand during what may be a long trial process.

Sentencing Trends: What JUDCOM Says When Convictions Occur

Even though many uncorroborated sexual assault allegations result in acquittals or withdrawals, some proceed to conviction. According to Judicial Commission sentencing statistics, NSW courts emphasise the seriousness of sexual autonomy violations. However, they also recognise that in borderline cases, where there is no force, threats or injury, sentencing must reflect proportionality. Mitigating factors such as prior good character, remorse and insight, lack of criminal history, and rehabilitation prospects significantly reduce penalty severity.

Where the evidence is weak but sufficient for guilt, courts still exercise caution. Judges often acknowledge, in sentencing remarks, the need to avoid excessive punishment where the offence arises from miscommunication, intoxication, or social misperceptions rather than predatory behaviour.

How National Criminal Lawyers® Defend “He Said, She Said” Sexual Assault Allegations

Our sexual assault defence lawyers approach these cases with extreme precision. We examine every detail of the complainant’s account, scrutinise inconsistencies, and reconstruct the timeline through messages, CCTV, digital forensics, and witness statements. We frequently brief senior counsel for cross-examination, especially when a Murray direction or Longman warning is likely to be argued.

We also analyse the psychological dynamics of the allegation, the circumstances under which the complaint was made, potential motivations, intoxication effects, and communication patterns before and after the event. In many cases, we engage forensic psychologists or memory experts to explain how errors, suggestibility or emotional framing may influence recollection.

Many “he said, she said” matters are withdrawn before trial because of detailed defence submissions (including Representations to Police) showing that the prosecution cannot meet the required legal standard. For clients, this avoids the ordeal of trial and prevents life-changing consequences.
