The appointment is part of a new executive structure at the Australian airline, announced in a statement today.
Heading an information technology services division that sits separate from a new Qantas Shared Services area, Willett reports to chief financial officer and executive general manager strategy, Peter Gregg. Balfour -- who is set to join Telstra in April -- previously also looked after shared services such as property, procurement and financial services in her expanded role as executive general manager business services.
Willett -- who starts in his new role on 20 February -- was previously one of Balfour's direct reports.
The airline announced the new executive structure with its half year results, which recorded a net profit after tax of $352.6 million.
