Christopher Hill, one of the men at the centre of Australia’s biggest insider trading heist, says casual conversations in the office about workplace policies and deeper relationships between management and staff could have helped prevent the $8 million theft.

As detailed in The Australian Financial Review’s podcast, The Sure Thing, Hill helped university friend Lukas Kamay turn $10,000 of seed money into $7.8 million in late 2013 and early 2014, a crime that led to both men spending years behind bars.
