Rabobank Australia has appointed Caroline Oosterbaan as chief executive and Regional Manager for Australia and New Zealand, effective 1 March 2026\. Oosterbaan succeeds Mark Wiessing, who has retired after more than 20 years with the Dutch agricultural lender and more than two years leading the Australasian operations.

#### OOSTERBAAN'S BACKGROUND

Oosterbaan joins the Australian leadership from the Netherlands, where she served as Global Head of Clients and Portfolio Management for Rabobank's international Wholesale and Rural Business. 

Rabobank Australia operates primarily as a specialised agricultural lender, providing finance to farmers, food-processing companies, and agribusiness supply chains across the country. 

Wiessing had held the dual role of CEO of Rabobank Australia and Regional Manager since May 2023, and had spent more than two decades within the Rabobank group across multiple geographies and functions. The bank's media release confirmed his retirement from both positions effective 1 March 2026, and expressed appreciation for his long contribution to the group.
