Qantas will purchase 10 Fokker 100s for recently-acquired Network Aviation.
"Our intention from day one has been to grow Network, and today's announcement will increase its F100 fleet five-fold," chief executive Alan Joyce says in Sydney.
Three F100s will be delivered during the 2011 financial year ending 30 June. A further four will be delivered during the 2012 financial year, Qantas says.
Qantas last December purchased Perth-based Network Aviation to move into the booming fly-in-fly-out charter services for the mining sector in Western Australia.
"Mining company demand for fly-in-fly-out air services to transport employees to and from remote sites within the state, however, cannot be met solely by regular passenger transport services," Joyce said at the time of the acquisition.
Network Aviation operates a fleet of two 100-seat Fokker 100 aircraft and six 30-seat Embraer Brasilia EMB-120ERs, according to Flightglobal's ACAS database.
When the acquisition is finalised, Network Aviation will become a wholly-owned subsidiary of Qantas. It will retain its existing management, employees and operating structure.
