SYDNEY, Australia — The two top executives at one of Australia’s largest banks will depart after a damning report on misconduct in the country’s financial industry singled them out for their resistance to changing how they do business.

National Australia Bank said on Thursday that Andrew Thorburn, its chief executive, and Ken Henry, its chairman, would soon resign from the company. The bank cited the report issued on Monday by an Australian royal commission that castigated the industry for putting profit ahead of its customers and called for tougher regulations and accountability.

The report recounted moments during months of public hearings and submissions in which Mr. Thorburn dismissed systems failures that might have cost his customers over 100 million Australian dollars, or $71 million, as “carelessness.”

“Having heard from both the C.E.O., Mr. Thorburn, and the chair, Dr. Henry, I am not as confident as I would wish to be that the lessons of the past have been learned,” Kenneth Hayne, who led the commission that investigated questionable financial industries practices, wrote in the Monday report.
