Mention fraud as a possible factor in elections and you’re said to be in need of psychiatric assistance.

While measures against fraud at general elections have never been as rigorous in Australia as in some other democracies, they were significantly eased in the 80s, ostensibly to make voting easier. (Few voters at the time were aware that voting was difficult.) But the AEC has found no evidence of resulting widespread fraud.
