At 31 December 2017, there were 150,489 employees in the Australian Public Service. This was a 1.8% decline from December 2016 and the lowest December headcount over the last decade.

  • The 31 December 2017 headcount comprises 136,392 ongoing employees (90.6%) and 14,097 non-ongoing employees (9.4%).
  • The majority of the headcount decrease over the last 12 months is attributable to the decrease in non-ongoing staff—nearly 2,300 or 14%. While ongoing numbers also fell, this was only by about 500 or -0.3%.
  • Annual December headcounts have been steadily decreasing from a peak of 166,582 in 2011—a fall of just over 16,000 (Figure 1).
