Federal officials are examining if there are other instances of consultants leaking confidential government information after certain PwC partners and staff were caught sharing secret policy information with clients while advising on measures to combat tax avoidance.

Treasurer Jim Chalmers said he was furious with PwC, the nation’s largest accounting firm, over the leak and that Commonwealth agencies were already examining the work being done by advisers to ensure similar leaking “isn’t happening in other cases”.
