The Tech Council of Australia’s big backers are privately raising concerns about how the industry association for some of the country’s largest technology firms dealt with the exit of billionaire businessman Richard White from its board, a separation they say took far too long.

Mr White, the founder of WiseTech Global, resigned as chief executive of the logistics software giant and from his position on the Tech Council last week after an investigation by The Australian Financial Review, The Sydney Morning Herald and The Age revealed he had been accused of bullying and had purchased a multi-million dollar house for a female employee.
