Crimes Act 1961

Every one who in pursuance of a suicide pact kills any other person is guilty of manslaughter and not of murder, and is liable accordingly.

Where 2 or more persons enter into a suicide pact, and in pursuance of it 1 or more of them kills himself or herself, any survivor is guilty of being a party to a death under a suicide pact contrary to this subsection and is liable to imprisonment for a term not exceeding 5 years; but he or she shall not be convicted of an offence against section 179.

For the purposes of this section the term suicide pact means a common agreement between 2 or more persons having for its object the death of all of them, whether or not each is to take his or her own life; but nothing done by a person who enters into a suicide pact shall be treated as done by him or her in pursuance of the pact unless it is done while he or she has the settled intention of dying in pursuance of the pact.

It shall be for the person charged to prove that by virtue of subsection (1) he or she is not liable to be convicted of murder, or that by virtue of subsection (2) he or she is not liable to be convicted of an offence against section 179.

The fact that by virtue of this section any person who in pursuance of a suicide pact has killed another person has not been or is not liable to be convicted of murder shall not affect the question whether the homicide amounted to murder in the case of a third person who is a party to the homicide and is not a party to the suicide pact.
