Average Mining Project Assistant Salary in Australia for 2026

How much does a mining project assistant make in Australia?

A typical mining project assistant working in Australia brings home around 5,258 AUD a month before tax. Entry-level pay starts near 31,700 AUD, and the top of the ladder reaches roughly 92,200 AUD for the most experienced and specialised people in the role.

The wide gap between low end and top end reflects how much pay can vary inside the same job title. A junior mining project assistant working at a small local employer earns very different money from a senior at a multinational. Skills, employer, city and years in the seat all push the number around.

How mining project assistant pay ranges in Australia

A good way to think about salary in Australia is to look at the distribution rather than the headline average. Half of all mining project assistants in Australia earn less than 57,200 AUD a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

Looking at the quartiles fills in the picture. A quarter of earners take home less than 41,900 AUD (the 25th percentile), and a quarter clear 69,200 AUD (the 75th percentile). The middle 50% of mining project assistants sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 31,700 AUD. The highest stretch to 92,200 AUD, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

Mining project assistant pay by experience in Australia

Years of experience is the single biggest lever on pay for a mining project assistant in Australia, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical mining project assistant salary changes as you move through the career ladder.

The single largest jump on the ladder is from 2 - 5 Years to 5 - 10 Years, where pay rises by about 34%. That is the point at which a mining project assistant typically goes from "competent in the role" to "the person other people in the team learn from", and the market pays well for that step.

Mining project assistant pay by education in Australia

Education sits alongside experience as one of the biggest factors driving mining project assistant pay in Australia. Higher qualifications consistently pull higher salaries, but the size of the gap tends to be smallest at junior levels and widens as people move up. Two people in the same role with the same years of experience but different degrees can end up earning very different money once they reach mid-career.

Mining project assistant gender pay gap in Australia

The gender pay gap is a stubborn feature of almost every labour market, and Australia is no exception. Male mining project assistants in Australia earn an average of 63,900 AUD a year, while female mining project assistants earn around 60,700 AUD. That works out to a 5% gap in favour of men, even when comparing people doing the same work.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.

Pay raises for a mining project assistant in Australia

Most countries hand out at least some kind of pay raise every year, typically when an employee's contract is reviewed or as a cost-of-living adjustment to keep wages roughly in step with inflation. The rhythm and size of those raises varies hugely between industries.

A typical worker doing this role in Australia sees a raise of about 11% every 15 months, which works out to roughly 9% on an annual basis. That figure is the typical underlying rate; in years where inflation runs high you can usually expect a bit more, and in flat-economy years a bit less.

Across all jobs in Australia, the national average raise is around 8% every 16 months.
