Remuneration Outcomes by Various Parameters
As has been the case in previous reports, along with all the remuneration information, data concerning agency size, work location (by State) and job family have also been collected.
Mercer has conducted a One-Way Analysis of Variance (ANOVA) test to determine whether differences observed in the average TRPs for each of these groups was significant. The following tables reflect these analyses, which essentially assess whether the null hypotheses—that all the averages are the same—should be accepted or rejected.
The greater the ‘F’ value, the lower the probability that the observed differences could have occurred by chance. If the differences in the averages for each category could have occurred by chance in less than 1 per cent of occurrences (p≤ .01), we could safely reject the null hypothesis.
Agency Size
As can be seen in Table D.1, analysing TRP by size of agency (using employee numbers) shows that for SES 3, the average TRP was higher for agencies employing 2,500 or more employees than for the other size categories, and, for SES 1 and SES 2, the highest average TRP was paid by agencies with less than 100 employees.
| Agency Size | Band | ||
|---|---|---|---|
| SES 1 | SES 2 | SES 3 | |
| Less than 100 | $213,359 | $315,133 | -- |
| 100 to 499 | $213,119 | $265,354 | $341,134 |
| 500 to 999 | $204,474 | $256,992 | $337,089 |
| 1,000 to 2,499 | $211,541 | $260,959 | $328,633 |
| 2,500 or more | $211,248 | $266,367 | $344,877 |
| % Difference from min to max | 4.35% | 22.62% | 4.94% |
| F | 4.004 | 1.902 | 2.659 |
| p | <0.001 | 0.058 | 0.036 |
| significance | sg | ns | sg |
Although there were some large differences in average TRP for SES 2, these were not statistically significant, whilst the differences between TRP for SES 1 and SES 3 were statistically significant. This means that the differences noted between the different size categories for SES 2 were no more significant than the variation that naturally occurs within each group of similar sized agencies.
Tables D.2 to D.4 show Q1, median and Q3 values for Base Salary and TRP by agency size, for each SES classification.

Location
APS agencies employ staff in a wide variety of locations across all States and Territories. Within each SES classification, it could be expected that remuneration would vary to some extent by location, given the wide differentials in the labour market between different States, and also cost of living differences between capital cities and the main regional locations.
As can be seen from Table D.5, differences were observed in average TRP levels for SES 1 and SES 2 employees in different locations (SES 1: 7.21 per cent and SES 2: 8.45 per cent). These differences were statistically significant at both SES 1 and SES 2. There was insufficient data available to examine differences between TRP levels for SES 3 employees by location.
| Location | Band | ||
|---|---|---|---|
| SES 1 | SES 2 | SES 3 | |
| ACT | $210,202 | $264,609 | $343,955 |
| NSW | $215,766 | $262,047 | -- |

| F | 63.099 | 5.119 | 1.476 |
| p | <0.001 | <0.001 | 0.116 |
| significance | sg | sg | ns |
As can be seen from table D.5, SES 1 employees based in the Northern Territory earned slightly more than those based in other states, whilst the highest paid SES 2 employees were based in Victoria. SES 1 and SES 2 employees deployed overseas were the lowest paid within their band.
Job Family
For the analysis shown below by SES classification and job family, Mercer has not included categories where there were too few respondents, as well as excluding those coded as ‘other’ and ‘missing’. A summary of ANOVA outcomes are shown below.
| Job family | Band | ||
|---|---|---|---|
| SES 1 | SES 2 | SES 3 | |
| Audit | $208,535 | -- | -- |
| Communications | $210,648 | -- | -- |
| Corp Services | $213,126 | $253,810 | -- |
| Economics | $211,522 | $243,800 | -- |
| Engineering & Technical | -- | -- | -- |
| Finance | $213,250 | $282,136 | -- |
| HR | $207,191 | $275,898 | -- |
| IT | $212,250 | $265,659 | -- |
| Intelligence & Security | $220,489 | -- | -- |
| Legal | $215,982 | $265,037 | -- |
| Medical | $222,525 | $282,374 | -- |
| Management | $214,032 | $269,827 | $331,069 |
| Policy Development | $209,447 | $262,684 | $328,104 |

| F | 10.960 | 15.692 | 0.708 |
| p | <0.001 | <0.001 | 0.588 |
| significance | sg | sg | ns |
As can be seen, for SES 1 and SES 2 employees, average TRP values for the different job families are statistically significantly different. At SES 1, the Audit and HR job families were below other job families and Medical was the highest. At SES 2, the large difference of 15.69 per cent observed between different job family groups was also statistically significant, with Medical again the highest and Economics the lowest.
