69 I interpose at this point consideration of the collateral arrangement dealing with superannuation. Accepting, as I have, the evidence of the applicant in preference to that of the second respondent, it follows that the agreed rate for superannuation contributions was $2,000 per annum as alleged by the applicant and not $520.00 per annum as claimed by the second respondent. In any case, there were other factors supporting this conclusion. The availability of a superannuation benefit was, of course, the incentive the applicant needed to change employment from PGH to the first respondent - he was emphatic about that. The letter of 15 July 1980 was silent on the contribution rate, mentioning only it was a "non-contributing superannuation fund, which basically is a life assurance policy covering you for 24 hours, 7 days per week with a retirement payout figure, should you stay with us until the age of 65." However, the only documentary material initially produced concerning superannuation was by the applicant being a series of letters during August and September 1991, following the termination of the relationship between the parties, and the trust deed of the superannuation fund with the rules thereunder. In a letter dated 29 August 1991 to the second respondent as a trustee, the administrator of the fund, Scott & Co, indicated that "an initial contribution was made on behalf of the (applicant) for the year ended 30 June, 1980. No further contributions were made subsequent to that date". The quantum of the single contribution was not stated but it was said in the letter that on termination "the amount due to (the applicant) would be the above mentioned $6,570 less any long service leave, as appropriate". Then, during the course of the proceedings, the respondents' solicitor produced a letter dated 29 November 1993 from the first respondent stating that, with interest, the principal amount of $6,570 had increased to $7,377.94 as an amount due to the applicant.
