Women, junior workers, graduates and indigenous people will bear the brunt of a federal government order to cut 14,000 temporary workers, an analysis of government workplace statistics shows.

Graduate and indigenous recruitment will be slashed, hiring will be frozen across the bureaucracy and lead science organisation CSIRO will be among the the agencies hardest hit with the jobs of up to 1400 scientists and researchers threatened.

The public service workplace authority, the Public Service Commission, issued orders late on Thursday to departmental bosses not to renew any temporary contracts or casual positions and to begin sacking ''non-ongoing'' workers.

On another front, the AusAID graduate program has been scrapped as part of the government's $4.5 billion cut to the foreign aid budget.

Dozens of recruits preparing to start their careers in February have been told not to show up.
