Australia's defence ministry on Friday announced it will slash 1,000 civilian jobs as part of a belt-tightening exercise to bring the national budget back into surplus.
The move is expected to see Aus$300 million (US$321 million) in savings over three years.
"We believe that on the civilian employees front we can do more," defence minister Stephen Smith told reporters in Perth.
"One thousand civilian employees will not be required as a result of the introduction of greater efficiencies."
Reducing the projected workforce would be achieved by natural attrition, not hiring new staff and limited voluntary redundancies if required, the government said.
Military personnel will not be impacted.
The Australian government will announce its national budget on Tuesday, outlining in part how it intends to bring the bottom line back to surplus by 2012-13 as the country rides an Asia-driven mining boom.
