iii. more recently in Neat Holdings Pty Ltd v Karajan Holdings Pty Ltd (1992) 110 ALR 449 the High Court [per the joint judgment of Mason CJ, Brennan, Deane and Gaudron JJ] has put the matter in the following terms (at 449-450):
The ordinary standard of proof required of a party who bears the onus in civil litigation in this country is proof on the balance of probabilities. That remains so even where the matter to be proved involves criminal conduct or fraud. On the other hand, the strength of the evidence necessary to establish a fact or facts on the balance of probabilities may vary according to the nature of what it is sought to prove. Thus, authoritative statements have often been made to the effect that clear or cogent or strict proof is necessary "where so serious a matter as fraud is to be found". Statements to that effect should not, however, be understood as directed to the standard of proof. Rather, they should be understood as merely reflecting a conventional perception that members of our society do not ordinarily engage in fraudulent or criminal conduct and a judicial approach that a court should not lightly make a finding that, on the balance of probabilities, a party to civil litigation has been guilty of such conduct.
iv. The High Court has pointed out in Pascoe v Federal Commissioner of Taxation (Cth) (1956) 30 ALJR 402 at 403 [citing Cussen J in Cox v Smail [1912] VLR 274 at 283] that the evidence given by a man of his intention and state of mind, must:
be tested most closely and received with the greatest caution.
v. Courts have emphasized that the best evidence of a man's purpose is to look at what was actually done: ASX Operations Pty Ltd v Pont Data Australia Pty Ltd (No 1) (1990) 27 FCR 460 at 482-483.
