Having played a key role in NAB's financial management and strategic decisions, Goonan brings extensive experience to Westpac. His transition is expected to impact both banks as they navigate a competitive banking environment in Australia. Goonan took over as Chief Financial Officer of National Australia Bank in July 2023, having previously served as Executive General Manager of Group Strategy and Development. Since he stepped into the role, NAB's share price has risen by about 26% from July 1, 2023, up until the stock's last close on Friday. Meanwhile, Westpac has confirmed that its current CFO, Michael Rowland, will stay in his position until the current NAB CFO, Goonan, officially joins the bank. Westpac's shares rose by 0.7%, while NAB's shares dipped by about 0.4% as of 12:05 AM GMT. This shift comes amid a series of leadership changes at both banks over the past year.
