(a) extent and nature of the injuries inflicted: death was caused to one victim, and extremely serious and permanent injuries were occasioned to the other.
(b) number of people put at risk: the appellant stole the motor vehicle which was the subject of, or used in, these offences at about 4:00 pm on 3 May 2012. At that time he was affected by both alcohol and cannabis. The vehicle was stolen from a car park in Manuka and driven by the appellant to an oval in Hughes. After doing a burnout in Coxen Street, he drove into Webster Street and then towards the intersection of Webster Street with Groom Street. At the intersection of Webster and Groom Street the appellant collided with another vehicle. He did not stop after the collision, and drove his stolen vehicle along Groom Street to the intersection with Kent Street, then along Kent Street to the intersection with Kitchener Street, then along Kitchener Street to the intersection with Birdwood Street, then along Birdwood Street to the intersection of Colvin Street until he turned right onto Colvin Street and stopped the vehicle. He then got out of the stolen vehicle and inspected the damage to it. He then re-entered the stolen vehicle and drove it to a service station in the shopping centre in Hughes. After filling the petrol tank with petrol, he drove the vehicle away from the service station without paying for the petrol onto Conyers Street, then into Wisdom Street before turning into Yamba Drive. The appellant drove the stolen vehicle through a red traffic light at the intersection of Yamba Drive and Kitchener Street, and then along Yamba Drive towards the Canberra Hospital. Shortly after 4:35 pm he approached the traffic light controlled pedestrian crossing in front of the Canberra Hospital. The victims were crossing with the "walk" sign at the pedestrian crossing as the appellant approached on Yamba Drive. At that point he was travelling at about 118 km per hour. The appellant, of course, had a red light facing him at the pedestrian crossing. He drove straight through the red light, narrowly missing one pedestrian, but hitting the two victims. The appellant did not stop, but continued to drive long Yamba Drive until, about 150 m from the pedestrian crossing, he collided with a Ford Territory four wheel drive vehicle, forcing that vehicle into another vehicle and bringing the appellant's vehicle to stop. At the time these offences occurred children could be expected to be travelling home from school, and moderately heavy traffic could be expected on Yamba Drive. His path also took him past a major public hospital where it could be expected that people with limited mobility would utilise the pedestrian crossing. It is not possible to determine precisely how many people were put at risk by the appellant's driving, but it is fair to infer that it was a substantial number.
(c) degree of speed: the appellant was seen to drive at high speed and on the wrong side of the road on Wisdom Street and was also seen to drive at high speed on Kitchener Street. He was also travelling at 118 km per hour on Yamba Drive, a 60 km per hour zone, outside the Canberra Hospital when he struck the victims. The speeds at which the appellant drove reveal a callous disregard for the safety of other members of the community.
(d) degree of intoxication or of substance abuse: the appellant was affected by both alcohol and cannabis at the time he drove the stolen motor vehicle. In a taped record of interview with police the appellant confessed to being intoxicated during the course of his driving. He said that when he stole the car he was "pissed - couldn't see the road properly", and that while he was driving he was "in and out of consciousness". It is clear on the appellant's own version of events that he was highly intoxicated by the alcohol and cannabis he had consumed.
(e) erratic or aggressive driving: from the point at the oval at Hughes where the appellant did a burnout to the point where he collided with the Ford Territory the appellant was observed to drive erratically on multiple occasions.
(f) competitive driving or showing off: this was not a feature of the appellant's driving.
(g) length of the journey during which others were exposed to risk: the length of the journey was not great, being no more than about 4 km. This was not, however, a case of momentary inattention or lapse of concentration, and the journey was through suburban areas at peak hour.
(h) ignoring of warnings: this was not a feature of these offences.
(i) escaping police pursuit: in his record of interview the appellant conceded that he drove as he did on Yamba Drive so as to avoid police apprehension for driving a stolen motor vehicle.
(j) degree of sleep deprivation: this was not a feature of these offences.
(k) failing to stop: the appellant failed to stop his vehicle after colliding with the victims, callously leaving them where they lay on the road. He continued to drive for another 150 m before colliding with another vehicle, and then attempted to flee the scene on foot.
