The degree of violence by the offender
14 The offender used his knife to inflict fatal wounding. Having stabbed the deceased in the back of the neck, the offender only stabbed the deceased once in the abdomen, but the severity and gravity of the wound is well described in the passage in the report of Dr Lyons which I set out earlier in these sentencing remarks. However I must bear in mind that this was not a prolonged knife attacked in which many abdominal stab wounds were inflicted.
15 I must carefully weigh the issues identified in Alexander as reviewed in my assessment of the objective gravity of this crime of manslaughter.
16 The offence of manslaughter involves the unlawful taking of human life, and as such it has always been regarded as a most serious offence. See R v Hill (1981) 3 ACR 397 per Street CJ at 402 and R v McDonald (NSWCCA, unreported, 12 December 2005). In R v Morabito (1992) 62 ACR 82 at 85 Wood J, as he then was, referred to the fact that manslaughter, even when committed after a prolonged period of provocation, was to be regarded as a major crime calling for a "grave measure of criminal justice". See also R v Mohamad Ali [2005] NSWSC 334 at [58].
17 Objectively viewed the offence committed by the offender was a serious one indeed.
18 Before considering the requirements of s 21A of the Crimes (Sentencing Procedure) Act 1999 (NSW) I review the subjective features as emerged on the hearing.
19 The offender was born on 14 March 1985. He comes from an unfortunate background in that his parents separated when he was five or six years of age and it was the offender's perception that his father had been violent to his mother. As a young child he remembers being with his mother and his sister when the father's body was discovered in the flat where he had been living and his father had died a violent death.
20 The offender had the support of his grandparents. He attended high school and achieved his school certificate before enrolling in Manufacturing/Engineering at TAFE. He did not complete this course. The relationship with Ms Barton began when he was 16 years of age. The offender lived for a period in Sydney but then in 2006 moved to the North Coast and settled in Stuarts Point. Here the offender obtained work at the Yarrahapinni Nursery. He was a nursery hand with this employer from September 2006 until November 2007 performing a range of nursery tasks. Ms Dobson, the managing director of the nursery company presented to the Court a glowing reference of the offender and Ms Dobson also attended Court and gave some evidence. Ms Dobson spoke very favourably of the offender and expressed her ongoing willingness to support him when he has served the sentence inevitably to be imposed. The offender left the nursery to work in the concrete industry. He worked on the Bonville Bypass as a concreter, form worker and steel fixer, and then obtained work with Australian Precast Solutions in Macksville where he was working until the time he committed this offence.
21 A significant number of favourable testimonials have been provided to the Court: one from his uncle, Peter David Lynch; one from Stuarts Point carpenter Steven Smith; one from a former employer Colin Leibe; one from a former workmate Keith Megson; one from Stewart Young and Mark Ngo for whom the offender is presently working in the engineering workshop at Parklea Correctional Centre; finally, one from his TAFE teacher Brian Sheekey who has stated that the offender is enrolled in the Certificate III course in Engineering Fabrication Trade. Mr Sheekey reports that the offender is following instructions and shows great enthusiasm and skill towards each task.
22 Anita Duffy, psychologist, assessed the offender on 31 August 2010 and provided a report on 2 September 2010. I have drawn on Ms Duffy's report as well as the offender's affidavit in setting out the back ground pertaining to the offender. Ms Duffy conducted an assessment and following this in the opinion expressed said inter alia:
