53 It was John's evidence that in 1975 George requested that John led him $10,000 to buy a truck. George was trying to establish a trucking business of his own. John said he felt an obligation to help, so that although he hadn't $10,000 to spare, he did send to George by post office orders $7,500 in 1975 and a further $1,400 at the beginning of 1977. He produced bank passbooks showing withdrawals of the two amounts as some confirmation of this. George denies these events occurred. George's evidence, under cross-examination, had some consistency with John's evidence, however, in that George confirmed that he was short of money at that time and that he was trying to build up a trucking business. It was also John's evidence, denied by George, that in 1978 he accepted a proposal by George that, instead of repaying the $8,900 in cash, George would build a shed on John's land at Lot 17 Rockingham, which could be used in the family business in the meantime. A shed was built by George in 1978, on Lot 17 Rockingham. While George asserted this had cost some $7,500, in fact under cross-examination it appeared that only $4,500 was outlaid. The remaining $3,000 was explained as an estimate of the value of George's own labour on the flooring. George contended that his construction of the shed on Lot 17 Rockingham, at the expense of the family business, demonstrated that at that time he believed, and acted to his disadvantage on the basis, that Lot 17 was in truth his and that John had no interest in it. As a matter of an assessment of the relative credibilities of John and George as they gave their evidence on this issue, however, I am persuaded that the evidence of John regarding the $8,900 and the shed is to be preferred. It also has some external and contemporary support, in my finding, from the bank passbooks and the construction of the shed.
