STEM degrees remain an important pathway into Australia's technology, engineering, infrastructure, energy, resources, and scientific industries. However, demand is not uniform across every STEM field.

Australia's latest 2025 Occupation Shortage List (OSL) shows that labour-market shortages have eased overall. In 2025, 29% of occupations were classified as being in shortage, compared with 33% in 2024 and 36% in 2023. Despite this improvement, shortages remain across several professional and technical occupations.

It is important to distinguish between an in-demand degree and an in-demand occupation. Australia's government measures shortages at the occupation level rather than ranking university degrees by demand. Therefore, the STEM degrees below are included because they provide pathways into occupations with current demand, skills shortages, or strong long-term employment prospects.

1. Civil Engineering

Civil engineering is one of the strongest STEM options for students interested in Australia's infrastructure and construction sectors.

Civil engineers work on roads, bridges, railways, buildings, water systems, transport infrastructure, and other major projects.

Jobs and Skills Australia has identified civil engineering among occupations that have experienced skills shortages, while Australia's continued investment in infrastructure supports ongoing demand for engineering professionals.

Potential Careers

• Civil engineer
• Structural engineer
• Transport engineer
• Geotechnical engineer
• Water engineer
• Infrastructure engineer
• Construction project engineer
• Environmental engineer

Civil engineering can be particularly attractive to international students because infrastructure projects occur across Australia's major cities as well as regional areas.

2. Electrical and Electronic Engineering

Electrical and electronic engineering provides pathways into Australia's energy, telecommunications, automation, electronics, manufacturing, and infrastructure sectors.

The field is becoming increasingly important as Australia expands renewable energy, electrification, digital infrastructure, and advanced manufacturing.

However, students should understand that shortage classifications can change. Some engineering occupations that experienced shortages in previous years moved out of shortage in 2025 as labour-market conditions changed.

Potential Careers

• Electrical engineer
• Electronics engineer
• Power systems engineer
• Telecommunications engineer
• Control systems engineer
• Automation engineer
• Renewable energy engineer
• Embedded systems engineer

The degree can also provide opportunities in emerging areas such as electric vehicles, renewable energy systems, robotics, semiconductor technology, and industrial automation.

3. Mechanical and Industrial Engineering

Mechanical engineering provides one of the broadest technical pathways into Australia's economy.

Mechanical engineers work across manufacturing, mining, energy, transport, construction, robotics, and industrial systems.

Industrial and production engineering similarly focuses on improving manufacturing processes, productivity, automation, and industrial operations.

Jobs and Skills Australia's 2025 shortage analysis shows that Industrial, Mechanical and Production Engineers moved out of shortage compared with 2024.

This does not mean mechanical engineering is no longer a valuable degree. Rather, it demonstrates that current shortage status can change as the supply of qualified workers and employer demand change.

Potential Careers

• Mechanical engineer
• Industrial engineer
• Production engineer
• Manufacturing engineer
• Robotics engineer
• Automotive engineer
• Maintenance engineer
• Mechanical design engineer

The broad applicability of mechanical engineering can provide graduates with flexibility when labour-market conditions change.

4. Computer Science and Software Engineering

Computer science and software engineering provide pathways into Australia's digital economy, including software development, artificial intelligence, cloud computing, data engineering, cybersecurity, and systems development.

The demand picture for technology careers requires careful interpretation.

Jobs and Skills Australia's 2025 data show that Software and Applications Programmers moved out of shortage nationally in 2025.

This means computer science should not be presented as a guaranteed shortage occupation.

However, software remains a major professional occupation in Australia, with thousands of businesses continuing to rely on software development, digital infrastructure, data systems, and technology services.

Potential Careers

• Software engineer
• Software developer
• Application developer
• AI engineer
• Machine learning engineer
• Cloud engineer
• Data engineer
• Systems engineer
• Cybersecurity professional

Students choosing computer science should focus on developing practical and specialized skills rather than relying on the degree title alone.

5. Environmental Engineering and Environmental Science

Environmental and sustainability-related STEM fields are becoming increasingly relevant as Australia manages climate risks, environmental regulation, renewable energy development, water resources, and the transition toward a lower-emissions economy.

Students can enter environmental careers through environmental engineering, environmental science, ecology, earth science, or related degrees.

Jobs and Skills Australia's clean-energy analysis identified Environmental Scientists among occupations that could experience future skills shortfalls as Australia transitions toward net zero.

Potential Careers

• Environmental scientist
• Environmental engineer
• Sustainability specialist
• Environmental consultant
• Water resources specialist
• Environmental impact assessment specialist
• Climate and sustainability analyst
• Renewable energy environmental specialist

This field can be particularly suitable for students who want to combine STEM knowledge with environmental and sustainability work.

6. Surveying and Spatial Science

Surveying and spatial science is a specialized STEM field with applications in construction, mining, land development, infrastructure, mapping, and geographic information systems.

Surveyors and spatial scientists work with geographical data to measure and map land, support construction projects, manage property boundaries, and provide information used in infrastructure and resource development.

Jobs and Skills Australia reports approximately 18,500 people employed in the Surveyors and Spatial Scientists occupation group.

Potential Careers

• Surveyor
• Cartographer
• Geospatial scientist
• GIS specialist
• Land surveyor
• Spatial data analyst
• Remote sensing specialist
• Geomatics professional

The field is particularly relevant to Australia's construction and resources industries.

Students interested in this pathway can combine surveying with geographic information systems, remote sensing, satellite data, drones, and spatial analysis.

7. Chemical and Materials Engineering

Chemical and materials engineering provides pathways into Australia's resources, energy, manufacturing, pharmaceutical, food-processing, and advanced-materials industries.

However, current shortage data should again be considered carefully.

Jobs and Skills Australia's 2025 shortage-driver analysis shows that Chemical and Materials Engineers moved out of shortage in 2025 after being classified as a shortage occupation in 2024.

The change reflects an easing of labour-market pressure rather than the disappearance of the occupation.

Potential Careers

• Chemical engineer
• Materials engineer
• Process engineer
• Production engineer
• Energy engineer
• Pharmaceutical engineer
• Process safety engineer
• Materials scientist

The degree remains particularly relevant to Australia's resources, energy, advanced manufacturing, and industrial sectors.

8. Mathematics, Statistics and Data Science

Mathematics, statistics, and data science provide pathways into technology, finance, research, government, healthcare, and business analytics.

The increasing use of artificial intelligence, automation, and data-driven decision-making has made quantitative skills increasingly valuable across different industries.

Students can enter this area through mathematics, statistics, data science, computer science, or related degrees.

Potential Careers

• Data scientist
• Statistician
• Mathematician
• Actuary
• Quantitative analyst
• Data analyst
• Research scientist
• Risk analyst
• Machine learning specialist

Students choosing this pathway can strengthen their employability by developing programming, statistical modelling, and data-analysis skills.

Most In-Demand STEM Degrees Compared

Australia's official shortage system evaluates occupations rather than university degrees. Therefore, this comparison should be viewed as a guide to degree-to-career pathways rather than an official government ranking of STEM degrees.

STEM Degree	Representative Career Pathways	Demand Context
Civil Engineering	Civil, structural and infrastructure engineering	Strong infrastructure demand
Electrical & Electronic Engineering	Electrical, electronics, power and automation	Important long-term sector
Mechanical & Industrial Engineering	Mechanical, manufacturing and production engineering	Broad demand; shortages have eased
Computer Science & Software Engineering	Software, AI, cloud and systems	Large occupation; shortage eased nationally in 2025
Environmental Engineering/Science	Environmental, sustainability and climate roles	Potential future skills demand
Surveying & Spatial Science	Surveying, GIS and geospatial science	Strong applications in construction and mining
Chemical & Materials Engineering	Chemical, materials and process engineering	Shortage status eased in 2025
Mathematics, Statistics & Data Science	Data, actuarial, quantitative and analytical careers	Broad cross-industry applications

The 2025 Occupation Shortage List found that 29% of Australian occupations were in shortage, down from 33% in 2024. The decline shows that Australia's labour-market demand can change significantly from year to year.

Why STEM Demand Is Changing in Australia

Several major developments are influencing Australia's STEM labour market.

Energy Transition

Australia's transition toward renewable energy and lower-emissions technologies is increasing demand for engineering, environmental, energy, and technical skills.

Jobs and Skills Australia's clean-energy analysis identifies engineering and environmental occupations as important to Australia's transition toward net zero.

This creates opportunities for graduates with backgrounds in electrical engineering, mechanical engineering, environmental science, chemical engineering, and related fields.

Infrastructure Development

Australia continues to require engineers and technical professionals for transport, construction, utilities, housing, water systems, and other infrastructure projects.

This supports demand for civil, electrical, mechanical, environmental, and related engineering skills.

Digital Transformation

Australian businesses increasingly rely on software, data, cloud systems, cybersecurity, and digital infrastructure.

However, the technology labour market has become more competitive in some areas. Australia's 2025 shortage data demonstrate that occupations previously experiencing shortages can move out of shortage as labour-market conditions change.

Mining and Resources

Mining continues to be an important source of technical employment in Australia.

The sector creates opportunities for engineers, geologists, environmental scientists, surveyors, spatial scientists, and other technical professionals.

This is particularly relevant in resource-producing states such as Western Australia and Queensland.

Best In-Demand STEM Degrees for International Students in Australia

International students should look beyond a simple shortage-list ranking when selecting a degree.

Civil engineering is a strong option for students interested in infrastructure and construction.

Electrical engineering can provide pathways into energy, telecommunications, automation, and advanced infrastructure.

Computer science offers considerable flexibility across industries, but students should recognize that Australia's national shortage classification for software and applications programmers changed in 2025.

Surveying and spatial science can be particularly useful for students interested in construction, mining, infrastructure, and geospatial technology.

Environmental science and engineering may benefit from Australia's long-term transition toward cleaner energy and environmental sustainability.

Students should also consider where employment opportunities are concentrated. Some of Australia's strongest STEM opportunities are located outside the country's largest cities, particularly in mining, energy, infrastructure, agriculture, and environmental services.

STEM Degrees and Australia's Skilled Migration System

For international students, labour-market demand can also matter because Australia uses occupation-based skilled migration and employment systems.

However, students should not assume that an occupation appearing on one Australian shortage list automatically guarantees permanent residency.

The Occupation Shortage List measures labour-market shortages. It is not itself a visa list. Jobs and Skills Australia explains that its shortage analysis supports government workforce planning and policy development.

Australia's Core Skills Occupation List (CSOL) is a separate policy instrument used for certain skilled migration purposes. Jobs and Skills Australia also notes that inclusion on the CSOL does not mean an occupation receives higher visa priority.

International students should therefore check current visa requirements and occupation lists separately rather than assuming that studying an "in-demand" STEM degree guarantees a migration outcome.

How to Choose an In-Demand STEM Degree in Australia

1. Check the Occupation Behind the Degree

Universities award degrees, but employers hire people into occupations.

A computer science degree, for example, can lead to several occupations with different levels of demand.

Students should identify the occupations they could realistically enter after graduation.

2. Check Current Shortage Data

Australia's Occupation Shortage List changes as labour-market conditions change.

The 2025 list shows why students should not rely on outdated shortage lists. Only 29% of occupations were classified as being in shortage in 2025, compared with 36% in 2023.

3. Consider Long-Term Demand

An occupation that is not currently classified as being in shortage can still have strong long-term prospects.

Civil engineering, environmental science, energy engineering, software, and other technical fields can be affected by infrastructure investment, technological development, demographic changes, and economic conditions.

4. Build Practical Skills

A STEM degree becomes more valuable when combined with practical experience.

Students can strengthen their employability through:

• Internships
• Industry placements
• Research projects
• Professional certifications
• Technical software
• Programming
• Laboratory experience
• Engineering projects
• Industry networking

5. Consider Regional Opportunities

Some STEM occupations have strong opportunities outside Australia's largest cities.

Mining, surveying, engineering, environmental science, agriculture, energy, and infrastructure can all create employment opportunities in regional areas.

International students who are open to regional employment may therefore have access to a wider range of opportunities.

Post-Study Work Options for STEM Graduates

Australia's post-study work system is another factor international students should consider.

Eligible graduates may qualify for the Temporary Graduate visa (subclass 485) after completing an eligible Australian qualification, subject to the requirements in effect when they apply.

The visa can provide an opportunity to gain Australian work experience after graduation.

However, post-study work rights should not be treated as a guarantee of permanent residency.

Students who intend to remain in Australia permanently should separately research employer-sponsored pathways, skilled migration, state and territory nomination, and other applicable visa options.

Australian immigration policies can change, so students should verify the current requirements before making an education or migration decision.

Final Thoughts

Australia continues to offer strong opportunities for STEM graduates, particularly in civil engineering, electrical and electronic engineering, mechanical engineering, computer science, environmental science and engineering, surveying and spatial science, chemical and materials engineering, and mathematics or data-related fields.

However, Australia's latest labour-market data show why an "in-demand STEM degree" list needs to be interpreted carefully.

The 2025 Occupation Shortage List found that overall shortages had eased, with 29% of occupations classified as being in shortage compared with 33% in 2024. Several professional engineering and ICT occupations also moved out of shortage.

For international students, this does not make STEM degrees less valuable. Instead, it means students should choose degrees based on a combination of current labour-market demand, long-term industry growth, career flexibility, location, practical skills, professional requirements, and post-study opportunities.

A degree that connects to multiple occupations can be particularly valuable because labour-market conditions can change during the three or four years it takes to complete a university qualification.

The strongest strategy is therefore not simply to choose the STEM degree with the longest shortage-list history. It is to choose a field where the student's skills, the Australian labour market, and long-term career opportunities overlap.
