In 1971, New South Wales detective sergeant Philip Arantz discovered through a police computerisation program that reported crime figures had allegedly been systematically understated for years. He concluded that the data suppression concealed police corruption and possible links to organised crime, potentially reaching Police Commissioner Norman Allan. After senior officers rejected his complaints, Arantz worked with journalist Basil Sweeney to publish official figures in The Sydney Morning Herald showing that reported crime in 1971 was 75 percent higher than in 1970—an increase the source says could not plausibly be explained by a sudden crime wave.
The disclosure triggered retaliation rather than an immediate investigation. Arantz was suspended, compelled to undergo psychiatric assessment, and dishonourably discharged after Commissioner Allan allegedly led efforts to discredit him. The New South Wales government under Premier Neville Wran paid Arantz $250,000 in 1985, and special legislation in 1989 provided for his notional reinstatement and publicly vindicated his claims. Allan and former premier Robert Askin had already retired by then; Arantz later documented the episode in his 1993 book A Collusion of Powers.
