Umeoka will leave Microsoft in late December to pursue 'a new career opportunity' in the US closer to his family. Fellows will step up into the role in 22 December and will relocate from Sydney to Singapore.
'The Asia Pacific region is incredibly diverse and dynamic,' Fellows said in a statement. 'It is also a place where we can do much to deliver on our mission to make technology available to the next generation of users, and I am keen to make the most of the opportunity to work with our partners and governments around the region to deliver on that commitment.'
'I am passionate about education and the role that technology can play in developing skills and improving learning, as well as advancing the role of women in the IT industry. We have a track record supporting these goals, and I am keen to ensure we build on these very strong foundations.'
There is a strong history of executives in the IT sector stepping up from Australian leadership roles to take on wider Asia-Pacific responsibilities, often from Singapore. Former SAP Australia and New Zealand chief Geraldine McBride, for example, was promoted to lead the company's Asia-Pacific operations in January 2007 before leaving earlier this year.
However, Microsoft could not today say whether Fellows would be directly replaced or who would take her position locally if so.
One executive who was seen by some parties as an eventual potential successor was the company's former director of business and marketing operations, Tony Ward, who had wide-ranging responsibility within Microsoft Australia under Fellows. But Ward resigned in July and was replaced by Nigel O'Rorke '” who has now only been in the role for a few months.
Out of the rest of Microsoft Australia's senior leadership team, one of the most high-profile executives is Pip Marlow, the company's public sector director.
