The sprawling waterfront home is the third property purchased for a woman Richard White is alleged to have a relationship with, but the first involving a staffer.

The stoush between the businessman and the Sydney wellness entrepreneur who was once his alleged lover erupted earlier this month.

Richard White and his fellow WiseTech Global billionaires have lost more than $2bn from their share wealth in the two weeks since his legal stoush with an ex-lover and subsequent controversies became public.

Billionaire Richard White and his ex-lover Linda Rogan have abandoned their legal fight. Ms Rogan filed a notice of discontinuance with the court late on Monday.

The businessman has previously said he was selling down his stake in the software giant he founded because investors were demanding shares be made available.

A new series of damaging allegations have wiped $6 billion from the company’s market value and an estimated $2 billion from Richard White’s personal wealth.

WiseTech Global ( WTCHF, Financial ), an Australian-based software firm, found that the value of its shares dropped by 18% based on allegations against Richard White, the firm's chief executive officer.
