The function
3 During the day of the accident the respondent had attended a function at Camp Markham, part of HMAS Stirling. The purpose of this function was to welcome new members of the diving team to which the respondent belonged and to farewell some members who were being deployed to Townsville and then on to the United States for military exercises.
4 The Tribunal made a careful review of the evidence and set out its findings of fact. If I may say so, the clear way in which the issues, evidence and findings are presented could serve as a model for Tribunal determinations; see AAT Act s 43(2B). The findings of the Tribunal can be summarised as follows.
5 The function was organised by the diving team social convenor, ABCD Shields, who was in charge of the team fund or "kitty". His Warrant Officer and Executive Officer Lieutenant McPhail approved. Those attending paid $10 each. The function was to commence at noon.
6 The prescribed normal working hours for the diving team were between 7.50 am and 3.50 pm each working day. The Tribunal said at [21]:
"As a general rule all personnel commenced leave at 4.00 pm. There is evidence that the team did not always work until 4.00 pm, including on some Fridays, depending on the work available at the time."
7 Members of the team arrived at the function at various times, some between 12.00 and 1.00 pm and others afterwards. A barbeque and beer keg were set up and sausages cooked. Soft drinks were also available. Personnel began socialising and drinking, discussing questions of issues of interest including work matters and in particular the deployment to Townsville and the United States. There were no formal speeches or proceedings. Lieutenant McPhail attended the function for some two hours. He left about 3.00 pm. Members of the team commenced leaving from some time after 2.00 pm although "quite a number" were still at the function at 3.00 pm when Lieutenant McPhail left. Petty Officer Davies left at this time, although he returned about 4.15 pm. The Tribunal said at [24]:
"I am satisfied that many left between 3.00 and 4.00 pm although quite a number were still at the function after 4.00 pm. In due course there were only eight or so remaining at the function and they continued there until around about 5.30 pm when a number of those remaining helped clean up the site. There is no evidence to indicate that an announcement was made that the function had concluded."
8 All or almost all of the diving team who were at work at the base that day attended the function. The number who attended was in excess of thirty and could have been as many as forty.
9 The Tribunal found at [28] that there was the "clear understanding of most members of the diving team that it was necessary for them to attend the function". The Tribunal found at [30]:
"that it was a common understanding among the members of the diving team that they were in fact required to attend the function at Camp Markham, and that is why almost all, if not all, members actually attended the function at Camp Markham, including senior personnel."
10 After reviewing the evidence about leave the Tribunal found at [32]:
"… leave was not piped or formally announced and it was quite unclear as to exactly when members of the team were free to take their leave. Leave was not good prior to the function at Camp Markham.
…
The team members generally believed that they were required to attend the function and could not simply proceed directly home."
11 At about 3.30 pm ABCD Shields started to pack up the barbeque and moved it to a secure place. Quite a number were still at the function after four. In due course there were only eight or so remaining and they continued there until about 5.30 pm when a number of those remaining helped clean up the site.
12 The respondent arrived at the function soon after 12.00 and remained until about 6.00 pm. He was drinking beer and soft drink during that time and probably some food. The Tribunal fund that he had consumed "a considerable amount of beer" and was under the influence of alcohol and therefore unable to ride his motorcycle safely when he commenced his journey home.
13 Shortly after 6.00 pm the respondent left Camp Markham on his motor cycle to ride directly to his residence. He turned left into Dampier Road and headed south towards the main gate of the base. The motor cycle veered onto the wrong side of the road and collided with a light pole. The respondent's helmet flew off and he was thrown about twenty metres in the air. He sustained serious injuries including significant impairment of brain function.
