In classrooms across Victoria each year, around 7,000 to 10,000 senior secondary students choose to study Physics as part of their Victorian Certificate of Education (VCE). For many, it’s a subject filled with challenge — equations, concepts that stretch imagination, and experiments that connect theory to the tangible world. Yet Physics stands apart from most other disciplines because of one critical fact: it is an enabling science. Physics opens doors. It is the foundation on which many Science, Technology, Engineering, and Mathematics (STEM) fields are built, influencing everything from renewable energy to space exploration, medical imaging, and artificial intelligence.
But despite its central role in modern innovation, the number of students taking Physics in senior school has been steadily declining — a trend that has raised concerns among educators, scientists, and policymakers alike. Understanding why Physics matters, and what we risk losing without a strong Physics pipeline, is essential for shaping the future of Australia’s STEM landscape.
The Foundations of an Enabling Science
To call Physics an “enabling science” is not a slogan — it’s a statement of fact. Physics underpins the principles that make other scientific and technological disciplines possible. Engineers rely on it to design bridges, aircraft, and electronic devices. Chemists use physical models to understand atomic interactions and energy transfers. Biologists employ physical methods in imaging, genetics, and biophysics. Even computer scientists and data analysts draw on the logic and mathematical reasoning that Physics cultivates.
In short, Physics teaches us not only what happens, but why it happens — and that habit of deep inquiry becomes invaluable across every STEM field.
Consider renewable energy: understanding photovoltaic cells requires knowledge of quantum mechanics and electromagnetism. Developing wind turbines or electric vehicles depends on mechanics, materials science, and thermodynamics — all grounded in Physics. Similarly, advances in medicine, from MRI scanners to radiation therapy, stem directly from discoveries in fundamental Physics. In space exploration, every satellite orbit and rocket trajectory is an applied Physics problem.
In each case, Physics doesn’t just explain the world — it enables humanity to build upon it.
The State of Physics Education in Victoria
According to the Victorian Curriculum and Assessment Authority (VCAA), 2023 saw approximately 9,700 students enrolled in VCE Physics Units 1–2 and about 6,800 in Units 3–4 completing the VCE physics exam. These numbers may sound healthy, but in context they represent a gradual decline from previous decades. In 2010, nearly 38% of eligible VCE students studied at least one “traditional” science subject (Biology, Chemistry, or Physics). That proportion has since fallen, with Physics particularly affected.
The gender distribution also reveals a persistent gap: in 2023, around 6,781 male students were enrolled in Physics Units 3–4, compared with only 1,507 female students. While efforts are ongoing to promote STEM equity, the numbers show that Physics continues to face an image problem — often seen as difficult, abstract, or “not for everyone.”
Yet the irony is that Physics offers everyone a unique intellectual toolkit. It cultivates the habits of problem-solving, quantitative reasoning, and creative experimentation that are crucial in the modern workforce. Whether a student becomes an engineer, an economist, or an environmental scientist, the thinking patterns developed through Physics remain invaluable.
The Decline of Physics Participation — and Why It Matters
The falling participation in Physics is not just a school-level issue; it’s a national concern. Across Australia, only about 12% of Year 12 students currently study Physics — down from nearly 20% two decades ago. The reasons are complex: increased subject choice, perceived difficulty, competition from subjects that scale differently for the Australian Tertiary Admission Rank (ATAR), and cultural perceptions that Physics is “too mathematical.”
But this decline has implications far beyond classroom walls.
- STEM Workforce Shortages:
Many high-demand industries — engineering, computing, data science, and advanced manufacturing — require graduates with a solid grounding in Physics. A smaller pipeline of Physics-trained students means fewer future professionals capable of working in these fields.
- Technological Innovation:
Physics fuels innovation. From quantum computing and semiconductors to nanotechnology and energy storage, the breakthroughs that define the 21st century rely on a deep understanding of physical laws.
- Economic Competitiveness:
Nations with strong STEM education systems tend to lead in innovation and productivity. Australia’s future prosperity — in renewable energy, medical technology, and defense — depends on a workforce fluent in the principles of Physics.
- Scientific Literacy:
Beyond careers, Physics education fosters scientific literacy. Understanding energy, forces, and motion helps citizens make informed decisions about issues such as climate change, sustainable technology, and infrastructure.
In other words, Physics is not just about producing physicists. It’s about producing thinkers who can navigate and shape a technological world.
Bridging the Gender Gap
The gender imbalance in Physics is one of its most persistent challenges. Nationally, male students outnumber females by roughly 4:1 in senior school Physics. This disparity reflects broader cultural factors — early socialisation, lack of visible female role models, and self-perceptions about ability in mathematics and science.
Yet studies consistently show that when provided equal encouragement and opportunity, girls perform just as well as boys in Physics. Initiatives such as “Girls in Physics” breakfasts, mentoring programs, and targeted outreach have begun to shift perceptions, but lasting change requires early intervention. Building curiosity and confidence in science from primary school onward is essential if we are to achieve gender equity in the enabling sciences.
Reframing Physics Education
If Physics is to thrive, it must be seen not as an elite or difficult subject, but as a gateway to discovery. Teachers, universities, and policymakers have key roles to play here:
- Contextualising Content: Showing how Physics connects to real-world problems — from climate solutions to medical imaging — makes learning more meaningful.
- Modernising Assessment: Encouraging creativity, design, and experimental thinking rather than rote mathematical manipulation.
- Promoting Career Awareness: Many students don’t realise how diverse Physics-related careers are — from finance and meteorology to robotics and astrophysics.
- Leveraging Technology: Interactive simulations, virtual labs, and data analysis tools can make abstract concepts tangible and engaging.
By modernising the way we teach and communicate Physics, we can inspire a new generation of students to see it not as an obstacle, but as a passport to opportunity.
A Call to Reignite Curiosity
Physics, at its heart, is the study of how the universe works. It asks the biggest questions — Why does time flow? What is light? How did the universe begin? These questions resonate with the natural human desire to understand, to explore, and to innovate. That curiosity has driven every leap of progress in human history.
Reigniting interest in Physics is not just about filling university quotas or boosting STEM numbers. It’s about keeping that spirit of curiosity alive — ensuring that Australia continues to produce thinkers who can navigate an increasingly complex world.
As we move deeper into the 21st century, the challenges we face — energy, environment, technology, health — will demand not just knowledge, but understanding. And understanding begins with Physics.
