Ultra was in the process of establishing its headquarters in Adelaide at the Mawson Lakes precinct and will build on the space that Avalon already has.
The company is seeking a share of the White Paper's billions, with the $80 million AWD sonar contract already on its books.
Managing director of Ultra Electronics Australia, Doug Burd, welcomed the White Paper's emphasis on sea defences, with new submarines and frigates as well as ongoing work on the AWDs and the LHDs.
"There are a lot of opportunities for a group like ours," Burd said.
