Twitter will unveil its first Australian headquarters this week.
The social networking giant has been steadily increasing its presence in Australia since late 2012, with a still-growing roster of staff and high-profile partnerships with several sporting codes and media organisations.
It will formally open its corporate offices in Sydney CBD this week, though staff members have been working from the building for several weeks.
Twitter also confirmed on Monday that it has appointed former Google Asia-Pacific executive Karen Stocks as its Australian managing director.
The opening of an office in Australia has long been rumoured, after Twitter set up a Twitter account for the Australian market. In January, Shadow Foreign Minister Julie Bishop said she understood that Twitter's move into Australia was "imminent".
The move comes as Twitter seeks to grow its pool of around 2 million Australian users and increase advertising revenue.
A permanent presence in Australia may also help streamline cooperation with local authorities, which have previously asked social network companies to play a greater role in the fight against online bullying.
Facebook increased its presence in Australia in 2009, hiring Mia Garlick, a former assistant secretary at the Department of Broadband, Communications and the Digital Economy. Facebook in Australia now operates under Managing Director William Easton.
Google also has corporate offices in Sydney.
