Assault and violence offences are treated as serious matters under South Australian law and can lead to significant penalties, including imprisonment. If you’ve been arrested, bailed, or summoned to court for an alleged assault, you need to seek legal advice immediately. At Caldicott + Isaacs, we have extensive experience defending clients charged with offences ranging from basic assault and causing harm to aggravated assault, assaulting police, manslaughter, and even murder.

Being investigated or charged by police can feel overwhelming and often gives the impression that you’ve already been found guilty. It’s important to remember that the burden of proof lies with the prosecution meaning they must prove beyond reasonable doubt that you committed the offence.

Our role is to stand between you and the police, to hold the prosecution to that standard, and to ensure that your rights are fully protected at every stage.

We examine every element of the allegation, from whether harm was actually caused to whether your actions may have been in self-defence. Assault charges often involve competing versions of events, and small details can make a big difference to the outcome. With the right preparation and representation, you can challenge the evidence, negotiate lesser charges, or even have the matter withdrawn.

Our expert defence lawyers defend assault and violence matters every day. Our lawyers appear regularly in the Adelaide Magistrates Court, District Court, and Supreme Court, representing clients across South Australia. We understand how the court system works, how prosecutors and police build their cases, and what strategies are most effective in defending them.

Our firm is known for its preparation, persistence, and strong advocacy. We take a strategic, evidence-driven approach to every case – identifying weaknesses in the prosecution’s evidence, exploring possible defences, and presenting your version of events clearly and persuasively. You will be guided through every step of the process with practical advice, regular updates, and a clear focus on achieving the best possible outcome.

If you’ve been charged with an assault or violence offence, don’t leave your future to chance. Contact us as soon as possible, ideally before your first court appearance or police interview so we can protect your position and start preparing your defence.

If you need more information about assault offences in South Australia, these FAQs answer the most common questions.

Do I need a lawyer for an assault charge?

Yes. Assault and violence offences carry serious consequences including convictions, fines, restraining orders, and imprisonment. A lawyer can analyse the evidence, identify defences, negotiate with prosecutors, and significantly improve your chances of a better outcome.

What should I do if police want to interview me about an alleged assault?

Contact us before speaking to police. Anything you say in an interview can be used as evidence. Early advice can prevent mistakes, protect your rights, and ensure you do not unintentionally damage your defence.

What if I received a summons or report to attend court?

You must obtain legal advice immediately. A summons means police believe there is enough evidence to prosecute you. Speaking to a lawyer early allows us to prepare your defence, request disclosure material, and protect your position before your first court date.

Can an assault charge be withdrawn?

Yes. Assault charges can be withdrawn if the evidence is weak, inconsistent, unreliable, or if a valid defence applies. We regularly negotiate with prosecutors to have matters downgraded or discontinued where appropriate.

Will I go to prison for an assault charge?

Penalties for these offences vary depending on the type of assault, level of harm, aggravating factors, and your history. Many first-time offenders avoid imprisonment with the right mitigation and defence strategy. Legal representation plays a major role in achieving this.

What is the prosecution required to prove?

The prosecution must prove beyond reasonable doubt that you intentionally or recklessly applied force, threatened another person, or caused harm. They must support their case with admissible evidence. It is not your job to prove innocence.

What is the difference between assault and causing harm?

Basic assault involves unlawful force or threats, while assault causing harm requires proof of actual physical injury. Causing harm carries heavier penalties. We examine medical evidence, witness statements, and the circumstances to challenge whether harm was truly caused.

What if I acted in self-defence?

Self-defence is a complete defence if you believed force was necessary and your response was reasonable in the circumstances. Many assault charges arise from misunderstandings, mutual arguments, or situations where a person was genuinely trying to protect themselves or others.

Can I be charged if the other person started the fight?

Yes. Even if you did not start the confrontation, you can still be charged. However, this may support a defence of self-defence or provocation. A lawyer can help present the full context of the incident.

What should I do if the alleged victim wants to drop the charges?

Only the prosecution can discontinue a charge. The alleged victim cannot withdraw it themselves. However, their cooperation or lack of cooperation can influence how the DPP or police proceed. We can advise on how this may affect your case.

How serious is assaulting police?

Assaulting police is treated very seriously by South Australian courts and can lead to imprisonment even for first-time offenders. The circumstances matter greatly, and strong representation is critical to reducing penalties.

What if the allegation is false or exaggerated?

False or exaggerated accusations are common in heated situations. We can challenge inconsistencies, credibility issues, motive, and unsupported claims. Independent evidence such as CCTV, messages, or witness accounts can be crucial.

Will an assault conviction affect my job or travel?

Possibly. Many employers conduct criminal history checks, and some countries restrict entry for people with violence-related convictions. A lawyer can help you seek outcomes that avoid a conviction where possible.

Do I have to appear in court?

Usually yes. For most assault matters, the accused must attend unless the court grants specific permission otherwise. We can advise on your obligations and appear with you to ensure you are supported throughout the process.

When should I contact a lawyer?

Immediately. Contact us as soon as possible after the incident, even before you are charged or questioned by police. Early involvement allows us to protect your rights, gather evidence, and prepare your defence before the matter progresses.
