18 The statements provided to Mrs S, which were in evidence before the Tribunal, are very difficult to understand, and cannot readily be married up with events in the chronology, to the extent that there is an agreed chronology. By way of example, I note that the statement dated 30 June 1995 shows a mortgage on the Arthur River Roadhouse with principal and interest owing as at 30 June 1995 in a sum exceeding $134,000. After deducting from that and the other assets of Mrs S (totalling a little over $139,000) moneys said to have been advanced by Duckham Thorpe and costs not billed, there is what is described as a "nett [sic] position (approximately)" of $112,235.67. In the statement dated 30 June 1997, two years later, there is an "opening balance" of $112,235.67, and an entry for notional interest of $11,223.57. Calculation reveals that that sum is 5 per cent simple interest applied to the opening balance. It is not clear why the interest was calculated only on the net position as at 30 June 1995, rather than on the balance outstanding on the loan from time to time. Nor is it clear where the figure of 5 per cent simple interest comes from.
