Perth Airport's 2009 master plan has received approval from Australia's government.
The plan involves a 10 year A$2.4 billion ($2.2 billion) investment programme, says Anthony Albanese, Australia's minister for infrastructure, transport, regional development and local government.
The plan includes the phased relocation of all passenger services to the airport's international precinct.
He also notes that the airport's main runway will be resurfaced in early 2010, and this will take seven weeks to complete.
