Murder in Australian law

In Australia, murder is a criminal offence where a person, by a voluntary act or omission, causes the death of another person with either intent to kill, intent to inflict grievous bodily harm, or with reckless indifference to human life.^[1] It may also arise in circumstances where the accused was committing, or assisting in the commission, of a different serious crime that results in a person's death. It is usually punished by life imprisonment. Australia is a federal nation and the law of murder is mostly regulated under the law of its constituent states and territories. There is also federal murder offence available in limited circumstances.^{[2] [3]}
