Billionaire WiseTech Global founder Richard White had a lengthy relationship with an employee and gave her a luxury waterfront mansion worth $7 million, sparking unease among board members already battling to contain the crisis engulfing the logistics software giant.

Christine Kontos, a product manager at the logistics software firm, was recruited by Mr White after the start of their relationship in 2016. When it ended seven years later, Ms Kontos was gifted the four-storey house in Melbourne’s harbour front Docklands, an investigation by The Australian Financial Review, The Sydney Morning Herald and The Age can reveal.
