4 The facts of the offence are as follows. The appellant and Brown met in Melbourne and travelled via Adelaide and Perth to Geraldton. The victim, Mr John Blood, was travelling further north on a fishing holiday. He offered the appellant and Brown a lift in his car in return for sharing fuel expenses. The three arrived in Exmouth on 27 October 2006 and camped at a local caravan park. By this time the appellant harbored an unreasonable hatred of the victim. The appellant indicated to Brown that he wanted to kill him. On Saturday night the three visited three beaches on the western side of the North West Cape to see turtles. It was at the last of the beaches that the victim was killed. When they arrived at the third beach at about 11.00 pm the victim parked his vehicle. The three walked southwards along the moonlit beach looking for turtles. After the three had walked along the beach about 50 m, the appellant said he had forgotten his cigarettes and jogged back to the vehicle. The appellant's actual intention was to fetch a weapon with which to kill the victim. The weapon was a piece of camping equipment which was a round metal bar with a hook on the end. The appellant caught up with Brown and the victim who were now 100 m along the beach. The appellant got the victim to look away from him on the pretext that he had seen a turtle in the water. When the victim looked in the direction of the water, the appellant used the metal bar to strike a very forceful and savage blow to the side of the victim's head. When the victim fell to the ground he was able to raise an arm to defend himself while the appellant continued to strike the victim to the back of his head about six times. The victim had not been rendered unconsciousness and while lying face down in the sand was able to take his wallet and keys from his pocket and throw them towards the appellant. He said words to the effect, 'Take my wallet, take my car. Just stop'. The appellant took the credit cards out of the wallet and demanded to know the victim's PIN number. The appellant pretended
