The Sydney Theatre Company has announced the appointment of Andrew Upton as the group's new Artistic Director, a role he has previously shared with wife Cate Blanchet.


Mr Upton will take the role following the final co-production in early 2013 after Ms Blanchet stands down from the role.


"After an extensive national and international search for a new Artistic Director, which identified a number of outstanding candidates, we considered that Andrew would be the best person to lead the company as it evolves into the next stage of its artistic development," STC Chairman David Gonski said.


"We are very pleased that we were able to convince Andrew to accept another three year term to continue this terrific creative momentum, after he and Cate made the decision to continue living in Australia. The board considers Andrew to be the best person to build on the outstanding work he and Cate have achieved."


Mr Upton thanked the Board for his appointment, saying he felt honoured to continue his participate in the organisation.
