"This new contract ensures the continued employment of nearly 100 local maintenance technicians and support personnel in Townsville," Minister for Defence Personnel, Materiel and Science Greg Combet said.
"The contract is a three-year contract worth approximately $35 million and has five one-year options.
"It will ensure the viability of the Black Hawk in a cost effective way until the end of its service life.
"This new contract offers increased value for money and a more balanced approach to risk when compared to the previous arrangements.
"The contract was sourced through a competitive open tender process and will provide for deeper maintenance services for the Black Hawk in Townsville."
The Black Hawk will remain the primary troop lift capability for the Army until it is replaced by MRH 90 and then withdrawn from service.
BAE opened a new aircraft maintenance centre in Townsville during 2009.
