More than 10 agencies among 175 that are being targeted by the federal government to save $500 million over the budget forward estimates have already been scrapped, calling into question the extent of the savings claimed.

Finance Minister Mathias Cormann said on Saturday that jobs would be lost "across the public service" as a result of the savings measures, which are expected to be announced in full on Monday as part of the Mid-Year Economic and Fiscal Outlook.

Senator Cormann said News Corp Australia had published a "pretty comprehensive list" on Saturday of the agencies, bodies and committees that would be affected.

Among the 175 government bodies identified on the hit list are four councils and committees established by the Council of Australian Governments, which were scrapped a year ago as part of a plan to reduce the number of councils from 22 to eight.
