Andrew Irvine officially stepped into the powerful role of CEO and Managing Director of National Australia Bank (NAB) in April 2024, inheriting the leadership of one of Australia's "Big Four" banks. His appointment, after a two-year succession planning process, was initially heralded as a "gold standard" transition. However, his early tenure has not been without its challenges, with recent reports highlighting scrutiny from shareholders.

Irvine, a British-Canadian dual citizen, brought a wealth of international experience to NAB, having spent over 12 years at the Bank of Montreal (BMO) in Canada, where he rose to become Head of Canadian Business Banking. Prior to that, he honed his skills at McKinsey & Company and Credit Agricole. He joined NAB in 2020 as Group Executive of Business and Private Banking, a division he is widely credited with significantly strengthening, making him a natural successor to the outgoing CEO, Ross McEwan.

His appointment was met with optimism. NAB Chairman Philip Chronican praised Irvine's "deep understanding of customers," his expertise in "digitisation, transformation and modernising," and his advocacy for the agricultural sector and small businesses. Irvine himself expressed excitement about leading a bank "core to the financial needs of so many Australians and New Zealanders."

Early Challenges and Scrutiny

Despite the initial positive reception, recent reports have brought Andrew Irvine's leadership style and professional conduct under the microscope. In July 2025, it emerged that NAB shareholders had reportedly raised concerns with Chairman Phil Chronican regarding Irvine's "professional demeanour" and even his drinking habits at company events. While no allegations of inappropriate behavior towards staff have been made, the scrutiny has been "difficult" for Irvine and his family, as he publicly acknowledged. He stated he expects scrutiny in his role but hopes it will be "even-handed and balanced."

Adding to the complexities of his early months, NAB has seen the departure of key executives, including highly respected Chief Financial Officer Nathan Goonan, who moved to rival Westpac. Rachel Slade, the former Group Executive of Business & Private Banking (Irvine's old role), was also replaced by Andrew Auerbach, a former colleague of Irvine's from Bank of Montreal. These executive changes, combined with reports of a significant share sale by Irvine in March 2025 (prior to the public announcement of some executive moves), have fueled internal discussions and external speculation.

The Road Ahead

Andrew Irvine's leadership will be crucial as NAB navigates a competitive banking landscape and addresses internal and external pressures. His mandate from the board is clear: to continue executing NAB's strategy to be the most customer-centric company in Australia and New Zealand. His background in business banking and his focus on digitization and customer needs remain key strengths.

As the current Chair of the Australian Banking Association (ABA) Council, Irvine also plays a significant role in advocating for a strong and stable banking system in Australia.

The coming months will be pivotal for Andrew Irvine. How he addresses the recent scrutiny, manages executive transitions, and delivers on NAB's strategic objectives will define the narrative of his early tenure and shape the bank's future trajectory. Observers will be watching closely to see how this internationally experienced banker steers NAB through these challenges and strengthens its position in the Australian financial sector.
