Electrical project engineers, mining engineers and project engineers are among the fastest-growing high-paying roles in Australia, with new data showing job advertisements for these positions have surged dramatically over the past year. The figures, drawn from a major employment platform covering the period from June to August 2026, paint a clear picture of where employers are spending their hiring budgets, and who stands to benefit most.

The Highest-Demand Jobs Paying Over $100,000

Job advertisements for electrical project engineers jumped 94 per cent compared to the same period last year, making it the fastest-growing role in the over-$100,000 salary bracket. The average advertised salary for the position sits at $149,043.

Close behind were mining engineers, where ad volumes climbed 87 per cent and average salaries reached $173,323. Project engineers rounded out the top three, with job ad growth of 65 per cent and an average salary of $157,015.

The full top 10 includes commercial managers, geotechnical engineers, health, safety and environment advisers, platform engineers, care managers, business service managers and workshop managers. Every role in the top 10 carries an average salary above $115,000, comfortably outpacing the average full-time Australian worker's annual earnings of $108,352.

The single most lucrative role in the group is commercial manager, where the average advertised salary reaches $208,298.

What's Driving the Surge in Engineering and Resources Jobs

The chief economist at the employment platform behind the data attributed much of the growth to two broad forces: commodity prices and public infrastructure spending.

"The price of some of Australia's key commodities has risen this year, supporting demand for those working in the mining, resources and energy industry," the economist said. "In particular, demand for mining and geotechnical engineers has grown quickly over the past year."

Large-scale infrastructure projects across most Australian states, including major rail programs in each of the eastern states, are also fuelling demand for project engineers, commercial managers and health, safety and environment advisers in the construction sector.

A third driver is the accelerating build-out of artificial intelligence-related data centres, which is creating demand for construction workers as well as platform engineers. Job advertisements for platform engineers rose 41 per cent over the period. "AI is fuelling demand for platform engineers, as businesses increasingly look to adopt the technology and require skilled workers to build and manage the IT infrastructure needed to support it," the economist noted.

Experience Counts More Than a Fresh Degree

Career coach Kate Richardson said she was not surprised by the strong showing from engineering, construction and mining, but she was quick to flag an important nuance in the data: most of the roles in demand are not entry-level positions.

"It's not dissimilar to cybersecurity, where there is a shortage of experienced technical people, and yet the competition at graduate level is incredibly high," Richardson said, using platform engineering as an example. "Job ads for platform engineers have increased by 41 per cent, however this is not an entry-level role."

She said the findings suggest employers are seeking highly skilled and experienced staff rather than fresh graduates, and that anyone considering a career pivot should look carefully at the actual volume of available roles, not just the rate of growth in job advertisements. The platform does not disclose exact advertisement volumes, which means percentage growth figures alone can sometimes overstate the scale of opportunity in absolute terms.

Richardson described a growing trend among her clients of pursuing shifts that build on existing skills and credentials rather than committing to a full undergraduate degree. "A lot of people I'm working with are exploring shifts in their career that build on their existing skills and expertise, and might require additional credentials but don't demand a full-blown bachelor's degree," she said.

She did highlight cases where a more dramatic change had paid off. One of her clients recently left a successful marketing career to study environmental engineering, motivated by the desire to work regionally, step away from desk-based work and make a tangible environmental contribution.

What Job Seekers Should Consider

For Australians weighing up a move into one of these high-demand fields, Richardson's core advice is to look beyond the headline growth figures. Understanding how many actual positions are likely to exist in a given field in the near future is just as important as knowing which categories are growing fastest.

"If you're thinking about a change, you want to understand not just which jobs are growing, but how many of those jobs there are actually likely to be in the near future," she said.

The data underscores a broader trend in the Australian labour market: as commodity prices, government infrastructure investment and AI adoption converge, demand for skilled technical and project management professionals is outpacing supply, pushing salaries well above the national average and creating real opportunity for experienced workers ready to move.
