Murder Lawyer Sydney
Experienced Criminal Defence Lawyers Representing Clients Charged With Murder In Sydney And Across NSW
Murder is the most serious charge in NSW and carries a maximum of life imprisonment. It is tried before a jury in the Supreme Court, and the case usually takes well over a year to reach that point.
At Hugo Law Group, our Sydney lawyers defend murder charges under the Crimes Act 1900 (NSW). A great many of these cases turn not on whether the accused caused the death, which is often not in dispute, but on what the prosecution can prove about their state of mind at the time.

Charged With Murder In Sydney?
To establish murder, the prosecution must prove that your act caused the death and that you acted with one of the states of mind the law requires.
Those states of mind are:
- An intention to kill
- An intention to inflict grievous bodily harm, meaning really serious injury
- Reckless indifference to human life, meaning you foresaw death as probable and acted anyway
- Or the death occurred during or immediately after a crime carrying a maximum of 25 years or more, known as constructive murder
Grievous bodily harm: really serious injury. The prosecution does not have to prove you intended to kill if it can prove you intended to cause injury of that severity.
How We Can Help With A Murder Charge
Murder trials are long, document heavy and decided by a jury on issues that are often narrow.
Our team can assist by:
1. Testing What The Prosecution Says You Intended
Intent is almost always proved by inference from the surrounding circumstances rather than directly. We examine whether those inferences are genuinely open, or whether a lesser state of mind is equally consistent with the evidence.
2. Advising You Before Police Interviews
Homicide investigations involve extensive questioning. We explain your rights and the consequences before you decide whether to participate, and no decision of that kind should be made without advice.
3. Identifying The Available Partial Defences
Certain defences do not result in an acquittal but reduce murder to manslaughter, which changes the maximum from life imprisonment to a term of years. Whether one applies is assessed from the evidence, not assumed.
4. Preparing And Running The Trial
Murder trials require sustained preparation, independent expert review and careful management of the evidence over a long period.

How Murder Can Be Established In NSW
For a murder conviction in NSW, the prosecution must prove both that the accused caused the person’s death and that the required state of mind existed at the time.
There are four ways a person can be found guilty of murder:
Intent to kill
The clearest form, requiring proof that you meant to cause death. Proved by inference from conduct, weapons used and what was said.
Intent to cause grievous bodily harm
Proof that you intended really serious injury, even if death was not intended. This is the most commonly relied on pathway.
Reckless indifference to human life
Proof that you foresaw death as probable and acted regardless. The level of foresight required is high and is frequently contested.
Constructive murder
Where death occurs during or immediately after a crime punishable by life imprisonment or 25 years, without any intent to kill or injure being proved.
Murder Penalties In NSW
Murder carries the highest penalties available in the state, and in limited circumstances a life sentence is mandatory.
| Offence | Maximum Penalty |
| Murder, s 18 Crimes Act 1900 (NSW) | Life imprisonment, under s 19A, served for the term of the person’s natural life |
| Standard non-parole period, ordinary cases | 20 years |
| Standard non-parole period, higher categories | 25 years where the victim was a child under 18, an intimate partner of the offender, or a police officer, emergency services worker or other public official killed because of their work |
| Mandatory life sentence, s 19B Crimes Act 1900 (NSW) | Required for the murder of a police officer in the course of their duty, where the offender knew or should have known who they were. Does not apply to offenders under 18 |
| Mandatory life sentence, s 61 Crimes (Sentencing Procedure) Act 1999 (NSW) | Required where the level of culpability is so extreme that no lesser sentence is adequate |
| Manslaughter, following a successful partial defence | Up to 25 years imprisonment, under s 24 Crimes Act 1900 (NSW) |
| Where the matter is heard | Murder is tried before a judge and jury in the Supreme Court of NSW |
A life sentence in NSW means the term of a person’s natural life. Where a life sentence is not imposed, the court sets both a head sentence and a non-parole period.
The intimate partner category in the standard non-parole period was added recently and applies to murders committed on or after 24 November 2025. For offences before that date, the earlier categories apply.
Because the gap between a murder conviction and a manslaughter conviction is so large, whether a partial defence is available is frequently the single most consequential question in the case.
Complete Defences And Partial Defences
The distinction matters. A complete defence results in an acquittal. A partial defence reduces murder to manslaughter, which removes the possibility of a life sentence.
Self-defence, a complete defence
Under s 418 of the Crimes Act 1900 (NSW), where you believed the conduct was necessary to defend yourself or another and the response was reasonable in the circumstances as you perceived them.
Mental health impairment, a complete defence
Under the Mental Health and Cognitive Impairment Forensic Provisions Act 2020 (NSW), where an impairment meant you did not know the nature and quality of the act or did not know it was wrong. The outcome is a special verdict of act proven but not criminally responsible, not a simple acquittal.
Extreme provocation, a partial defence
Under s 23 of the Crimes Act 1900 (NSW). Narrowed in 2014, it now requires the deceased’s conduct to have been a serious indictable offence, meaning one punishable by 5 years or more, and to have caused a loss of self-control.
Substantial impairment, a partial defence
Under s 23A of the Crimes Act 1900 (NSW), where a mental health impairment or cognitive impairment substantially impaired your capacity to understand events, judge right from wrong, or control yourself.
Excessive self-defence, a partial defence
Under s 421 of the Crimes Act 1900 (NSW), where you believed the conduct was necessary to defend a person but the force used was not reasonable, the verdict is manslaughter rather than murder.
Causation not established
Where the death resulted from another cause or an intervening event, the prosecution may be unable to prove your act caused it.
Where a partial defence succeeds, the verdict is manslaughter rather than murder, and the maximum falls from life imprisonment to a term of years.
What Happens After A Manslaughter Charge?
Homicide matters run over a long period, often more than a year from charge to trial.
- Investigation and charge
Homicide investigations are extensive. Charges are sometimes laid immediately and sometimes months later.
- Bail
Bail is contested in these matters and the test is demanding. An application needs to be prepared thoroughly rather than run at short notice.
- Brief of evidence
The brief includes post-mortem findings, expert reports, forensic evidence, witness statements and any recorded interview.
- Charge certification and case conferencing
The prosecution certifies the charges and the parties confer before the matter proceeds to the higher court. This is the stage where charge negotiations most often occur.
- Trial or sentence
The matter proceeds to trial before a jury, or to a sentence hearing on a plea. Either way the preparation is substantial.

Frequently Asked Questions
No. An intention to cause really serious injury is enough, as is reckless indifference to human life, meaning you foresaw death as probable and acted anyway. Murder can also be established where a death occurred during a very serious crime, without any intent to kill or injure being proved. This is why intent is so often the central contest rather than causation.
The line is drawn on state of mind. Murder requires intent to kill, intent to cause really serious injury, reckless indifference to human life, or a death caused during a very serious crime. Manslaughter covers unlawful killings where none of those is established, or where one is established but a partial defence reduces the verdict.
It is a defence that does not result in an acquittal but reduces murder to manslaughter, which removes the possibility of a life sentence. The recognised partial defences in NSW are extreme provocation, substantial impairment because of a mental health or cognitive impairment, and excessive self-defence. Whether any is available depends entirely on the evidence about what happened and about the accused.
It is granted rarely. Murder is treated as a show cause offence, so the onus falls on the accused to demonstrate why detention is not justified before the court considers the usual risk questions. An application requires substantial supporting material and should not be attempted without proper preparation.
It means imprisonment for the term of the person’s natural life, without a release date. It is the maximum for murder and is mandatory in limited circumstances. Where a life sentence is not imposed, the court sets a head sentence and a non-parole period after which parole may be considered.
Commonly well over a year, and often longer. The brief is large, expert reports take time, and Supreme Court trial listings add further delay. That period is when the defence case is built, so it is used rather than simply waited out.
