APRA has appointed two new executive general managers (EGMs) to its senior executive team, completing the regulator's transition to a new organisational restructure that was announced in May 2017.

Westpac head of risk analytics and insights Sean Carmody will join APRA in the newly created role of EGM, risk and data analytics.

Separately, in an internal promotion, current APRA chief risk officer Ben Gully has been appointed EGM, specialised institutions division.

APRA chairman Wayne Byres said the appointments will "refresh" the regulator's senior leadership team.

"Together with the appointments in May of four new senior executives, we have completed our organisational restructure designed to ensure APRA continues to respond to changes in the financial sector and deliver on APRA’s mission to protect the financial well-being of the Australian community," Mr Byres said.
