Geologist salary: Why the national line is just a starting point
If you’re looking at a geologist salary in Australia, the national full-time average of $108,352 a year (ABS Average Weekly Earnings, May 2026) is a useful benchmark, but it rarely tells the whole story. Geologists are concentrated in high-paying industries and states, and their pay is often set by enterprise agreements or individual contracts rather than awards. This page explains where the median geologist sits relative to the national line and what factors can push a salary higher or lower.
Where the median geologist stands
The most recent data from Jobs and Skills Australia (drawn from ABS surveys) shows that geologists, geophysicists and hydrogeologists have a median full-time weekly earnings of $2,914. That works out to about $151,500 a year before tax – well above the national full-time average of $108,352 and even further above the national full-time median of about $90,532. But this median comes with a caveat: geologists typically work 51 hours a week, compared to the national average of 44 hours for full-time workers. Their median hourly earnings of $61 are also higher than the national median of $47 for all occupations.
It’s important to note that the $2,914 figure is a median, not an average, and it includes all full-time geologists regardless of experience or location. The national line used on this site – $2,083.70 per week – is the average weekly ordinary time earnings for full-time adults, which excludes overtime and is measured across all industries. So a geologist earning the median is about 40% above that line.
Why state matters
State is one of the biggest drivers of variation. According to Jobs and Skills Australia, 51.8% of geologists work in Western Australia, where the mining industry dominates. Western Australia’s full-time average weekly earnings are $2,227.40 ($115,825 per year), the second-highest of any state after the ACT. The mining industry itself has an average weekly earnings of $3,224.20 for full-time adults – far above the all-industry average. A geologist working on a mine site in WA is likely to earn significantly more than one working in a government agency in Tasmania, where the state average is $1,846.30 per week ($96,008 per year).
Queensland employs 19.4% of geologists, with a state average of $2,039.70 per week ($106,064 per year). The remaining geologists are spread across other states, with smaller shares in NSW, Victoria, and South Australia. If you’re comparing a geologist salary to the national line, it’s essential to factor in where the job is based. See state and territory averages for more detail.
How award and agreement coverage shifts the figure
Many geologists are covered by enterprise agreements or individual contracts, especially in the resources sector. The Professional Employees Award 2020 sets minimum rates for some professional geologists, but actual pay is often well above award. The national minimum wage from 1 July 2026 is $26.44 per hour ($1,004.90 per week, $52,255 per year on 38 hours). Award minimums rose 4.75% in that adjustment, but geologist median hourly earnings of $61 are more than double the minimum.
For geologists in the public sector – for example, with state geological surveys or environmental agencies – pay is often set by collective agreements that follow public sector wage policies. These may be closer to the national average than the high end seen in mining. The public sector full-time average is $2,263.10 per week ($117,681 per year), while the private sector average is $2,034.10 ($105,773 per year). A geologist in a government role might earn around the public sector average, while one in mining could earn well above the private sector average.
Comparing to other occupations and industries
Geologists are classified as professionals, and the median hourly earnings for all professionals is $64.50 (ABS Employee Earnings, May 2025). Geologists at $61 per hour are slightly below that, but their longer hours push weekly earnings higher. The mining industry average of $3,224.20 per week is the highest of any industry, so geologists in mining is a strong performer.

Tax and take-home pay
Once you have a geologist salary, the next question is what you actually keep. The 2026–27 tax rates are: nil on the first $18,200, then 15% up to $18,200–$45,000, 30% up to $45,000–$135,000, 37% up to $135,000–$190,000, and 45% above that. The Medicare levy is 2% before reductions. For a geologist on the median $151,500, the tax would be roughly $38,000 plus Medicare, leaving about $110,000 after tax. But this is an estimate – use the salary line tool to calculate your exact take-home.
Summary
The national full-time average line of $108,352 is a useful reference, but a geologist salary is often much higher due to industry and location. The median geologist earns about $151,500, but that figure can vary by $20,000 or more depending on whether you’re in WA or Tasmania, in mining or government, and under an enterprise agreement or award. Always check the specific role and location before comparing to the national line.
