Software group WiseTech chief quits over 'personal attacks'

White, who had already quit as chief executive in 2024 over allegations including undisclosed "close personal relationships" in the workplace, is to remain as chief innovation officer.

The news sent WiseTech shares surging more than 10 per cent in morning trade on the Australian Securities Exchange.

"Recent personal media attention is creating an unnecessary distraction from the strength of WiseTech's business," White said in a statement, without providing details of the allegations.

"As I have stated previously, I strenuously and unequivocally deny the recent allegations in the media," he said.

"Further, I am conscious that personal attacks on me in the media that are unconnected to the performance of the Company nevertheless have the potential to encourage short selling activity."

WiseTech said Raelene Murphy, previously the firm's lead independent director, had been appointed as independent chair.

"My personal experience working with Richard is totally at odds with media reports," she said.

"I have found him to be an incredibly hardworking, focused and committed founder who has built a leading global technology business with enormous potential to continue to grow stronger."

Her appointment was a "step in the right direction", said a report by equity research group RBC Capital Markets.

"That said, while structural improvements in board composition are positive, the market will likely want to see ongoing evidence that the refreshed board, CEO, and Chief Innovation Officer, operate independently before attributing any meaningful re-rating."
