As outlined under section 18 of the Crimes Act 1900:
1. (a) Murder shall be taken to have been committed where the act of the accused, or thing by him or her omitted to be done, causing the death charged, was done or omitted with reckless indifference to human life, or with intent to kill or inflict grievous bodily harm upon some person, or done in an attempt to commit, or during or immediately after the commission, by the accused, or some accomplice with him or her, of a crime punishable by imprisonment for life or for 25 years.
(b) Every other punishable homicide shall be taken to be manslaughter.
Accordingly, to be convicted of a manslaughter charge, the police must prove beyond reasonable doubt that you committed a homicide without the intent to kill, or a homicide with reckless indifference to human life.
In NSW, the maximum penalty for the offence of manslaughter is imprisonment for 25 years.
