Ms Murphy joined the bank in 2016, bringing more than 20 years’ experience from multiple industries with her.
Ms Murphy said she enjoyed her role at NAB and was stepping aside to allow for a new team to lead the company forward.
“I have thoroughly enjoyed my time at NAB and have reached a useful point of reflection to consider other roles.
“It is important for the incoming CEO to have members of their leadership team who are utterly committed to the coming years,” she said.
NAB group chief executive officer Philip Chronican said that Ms Murphy had led the team through a challenging period and had helped built the organisation up.
“Building a truly customer-centric culture is more important than ever and Ms Murphy and her team have laid the foundations for us.
“She has rebuilt the function from the group up with structure, policies and process to best support the organisation,” he said.
A global search is underway to find a replacement; meanwhile, Julie Rynski, current customer executive regional and agribusiness, will take on the role in the interim.
Ms Rynski has more than 30 years of banking experience and joined NAB in 2017. She is responsible for delivering the bank’s strategy as the leading agribusiness bank in Australia.
