Expenditure on base salaries is the single largest component of personnel expenditure (others include superannuation, performance payments, redundancy costs, etc.). The total salary cost shown in the first tab on the chart below is calculated by multiplying the number of FTE employees in the Public Service by the average annual FTE base salary. These are approximate annual salary costs and do not represent total personnel expenditure. The total base salary cost in the Public Service increased by 12.9% ($554 million) to $4,841 million in 2020, up from $4,287 million in 2019. This was driven by a 8.6% increase in FTE staff numbers and a 3.9% increase in average salary.
Total salary cost by occupation group is the product of average base salary and the number of FTE staff in that group. The Manager group had the largest cost at $956.1 million in the year to 30 June 2020, as shown on the second tab in the chart above. The second largest cost was for the Inspectors and Regulatory Officers group at $761.7 million, followed by the Social, Health and Education Workers at $749.2 million. These three groups accounted for over half (51.0%) of Public Service employee salary costs.
The largest increases in salary cost by occupation group were for Information Professionals (up $127.1m or 22.4%), Other Professionals not elsewhere included (up $29.6 million or 14.6%) and Social, Health and Education Workers (up $88.4 million or 13.4%). They accounted for 44.2% of the increase in total base salary costs.
