Misconceptions and financial factors are stifling domestic PhD enrolments — but the engineers who do sign up say the experience is worth it.
For decades, the University of New South Wales (UNSW) has been a globally recognised force in engineering, training thousands of domestic and international students for professional and academic careers.
UNSW remains the Australian university with the most engineering PhD students — currently more than 900, according to Deputy Dean Professor Ian Gibson FIEAust.
But for several years that figure has barely risen. What’s more, three-quarters of UNSW’s PhD qualifications are now being awarded to international students, most of whom, Gibson said, do not remain in Australia after graduating.
The situation is reflected across Australia’s G8 universities. Although the total number of engineering PhD enrolments in Australia rose two per cent to 10,121 between 2018 and 2019 (the latest year for which figures were available), the number of domestic enrolments fell by 5.6 per cent.
“We’ve reached a point where we cannot find enough qualified domestic applicants to fill all the scholarships that are available,” Gibson said.
As a result, fewer PhD-qualified engineers are entering the workforce, which Gibson said is knee-capping Australia’s research and development (R&D) capability and hampering the nation’s competitiveness.
“Like other countries, more than 50 per cent of the research and development in Australia is conducted by industry,” he noted.
“But if you look at a technology company in, say, the US or Japan, many more of their staff have PhDs, which means they have been better trained to undertake R&D.”
Australian businesses are simply not getting engineers with the skills required to undertake world-leading research and development, Gibson said.
“That limits our ability to innovate and to be competitive in the global marketplace.”
Greener pastures
How did we reach this point?
Gibson said it’s partly because Australian industries are thriving, which means demand for engineers is high.
“It’s a very buoyant graduate marketplace,” he said.
“Starting salaries for graduates are very tempting.”
The average graduate engineer salary is above $70,000 per year. The alternative is to continue as a PhD student on a stipend of perhaps $30,000 per year.
That might be appealing if graduates believed a PhD would fast-track their careers. But Gibson said most engineering students think otherwise.
“A PhD is seen as a degree to do if you want to become an academic,” he admitted.
That is precisely what some graduates do want, but most engineers with an interest in research are keen to work in industry, according to Gibson.
“We need to change their perception that PhDs are only good for academia,” he said.
“It’s partly the universities’ responsibility. Currently, our PhD programs are not designed to attract people who want to work in industry.”
But he said employers have a role to play, too.
“We hear unhelpful messaging from some parts of the Australian industry that ‘a PhD is a waste of time’, in a way that you don’t hear overseas,” he said.
In fact, he pointed out, one of the reasons they have no trouble attracting international PhD students is because there is a recognition outside Australia that the qualification opens doors.
On the front line
Gibson said UNSW and other G8 universities could benefit from speaking to current PhD students and recent graduates to find out more about what encouraged them to pursue the qualification.
One such student, Constantine Tsounis, a third-year Scientia PhD Scholar at UNSW’s School of Chemical Engineering, said he signed up after encountering visionary PhD students and supervisors while he was an undergraduate.
“They convinced me that a PhD is not just about conducting research but also about developing professional skills to manage and lead organisations and have a positive impact on humanity,” he said.
Tsounis is unapologetically ambitious.
“I wanted a fast track towards positions that create wide-reaching positive environmental and social outcomes,” he said.
His PhD research into catalysts that can turn wastewater into clean hydrogen dovetails with his aspiration to help the world withstand and eventually reverse climate change.
Tsounis believes other young engineers would be more likely to enrol in PhD courses if the qualification was framed as a way to speed up, not slow down, a career.
Dr Arman Siahvashi, an Engineers Australia member and Forrest–Fulbright Postdoctoral Fellow in the Chemical Engineering Department at the University of Western Australia (UWA), agreed.
He didn’t realise how much he could achieve as a PhD student until he went to work in industry.
“After my master’s, I spent three years in oil and gas,” he said.
“But I needed something more challenging and intellectually stimulating than the work I was doing there.”
So Siahvashi enrolled in a PhD course at UWA.
“I saw it as an opportunity to combine my engineering skills and my imagination to invent and create something new and solve real-world industry problems,” he said.
Now, as a postdoctoral fellow, he straddles the line between academia and industry, collaborating with NASA and Chevron on commercial projects.
He said his PhD has enabled him to pursue his own R&D agenda at a time when the options to do so in Australian industry are limited. He also said the PhD gave him the opportunity to fail and eventually learn from his failures.
Facing struggles
Not all PhD students speak about the experience in glowing terms.
Anne Bettens, a PhD student at the University of Sydney’s School of Aerospace, Mechanical and Mechatronic Engineering, is pursuing the qualification to help her become an astronaut.
She says the tertiary sector seems to discourage all but a chosen few engineering graduates from becoming PhD students.
“It’s not financially viable to do it without a scholarship, and I really struggled to get funding at the beginning because of a paperwork issue that shouldn’t have been an issue,” she said.
“PhD students are struggling to get scholarships and struggling to get by.”
Bettens said she had not expected the process to be so arduous. She wondered if some engineering graduates are avoiding PhDs because they’ve heard about these funding and administrative issues.
“I’m glad I’m doing it, but I don’t think it should be portrayed as smooth sailing,” she added.
“You work very hard and there’s always difficulties, administratively and with funding. You need to be determined.”
Dr Ashley Roberts, an engineer at Woodside Energy and a US citizen, said that pursuing postgraduate qualifications has allowed her to travel internationally.
She went first to Europe, where she did research at the Center for Electron Nanoscopy in Denmark, and then to Monash University, where she conducted experiments at the Australian Synchrotron and the Australian Centre for Neutron Scattering.

In her experience, student researchers in Australia are not given as much freedom as those overseas.
“Some labs are just not efficient at enabling access,” she said.
Another problem: engineers such as Roberts, whose undergraduate qualification is not Australian, cannot use a PhD alone as a path to permanent residency.
That might be one reason so many international PhD students subsequently leave the country.
“There is a lack of recognition from Australia of the value we can add,” she said.
Forging ahead
Gibson said UNSW is taking steps to address some of the issues currently dampening enthusiasm for engineering PhD courses.
“We’re planning to introduce three new industry research degrees,” he said. “And we’re actively seeking to fund ‘top-up scholarships’ to remove the income differential between PhDs and graduate industry roles.”
But Gibson, who has worked as an engineer in computing and other industries, said solutions can only come if the business and tertiary sectors work together.
“This is hard for us to do by ourselves, but if we collaborate, everyone will benefit.”
I am keen to study a PhD, and I work full-time in industry. I have several projects that I could pursue for Master and PhD-level research that would greatly assist the industry I work in.
Earlier this year I called several universities for information about their PhD programmes. I quickly discovered the main barrier to study for industry professionals – it is the fact that universities require on-campus enrollment for PhDs. This alone would discourage many qualified professionals from continuing study past Master level. Even at Master level it is difficult to find research degrees that are not on-campus.
Perhaps within the next 5 years universities will have introduced a part-time, full-online option into their PhD programmes, because on-campus studies are not an option for me. I am happy to waive the stipend.
Can Prof. Ian Gibson accept me. I am 81 YO with more than 50 years in rolling stock experience. My subject is:
Hybrid Locomotive Powered from Hydrogen Fuel Cells for electric locomotives including Slip/Slide control and predictive wheel diameter compensation of each wheel powered by DTC inverters using permanent magnet AC traction motors. This is a world wide requirement and a development to assist Climate Change
Proposed PhD thesis by Bernard Schaffler. BSc Eng. MSc Eng. FIEAust. CPEng. MIEEE.
I only have to build the traction simulator and then it will be ready to convert filthy diesel locomotives.
Good read and highly accurate+relevant. I’m literally in this situation, where phd ambitions are based on affordability criteria both in terms of course fees and reduced salary.
I started PhD. Back in 2017 after completing my Bachelors in Mechanical Engineering with First Class Honours.
Even with full scholarship and leaving stipend, the PhD. was a massive financial burden and I withdrew after 6months. With the scholarship I was restricted to only 8hrs work per week and no one would hire an engineer with that restriction.
I completed my undergrad as a mature aged student with a full-time study load while working full-time as tradesman with six figure salary with mortgage and car loans commitments.
Following my PhD. withdrawal, I since enrolled and just completed a Masters of Engineering in Electrical Power, completing it within 2yrs while again working full-time as a Mechanical Engineer with a six figure salary.
Now the university has again invited me to consider continuing my studies with a higher degree by research. But again due to financial circumstances this will not be an option.
Thank you professor Ian Gibson. Your words are vissionary. I am currently working in the construction industry and studying part time for many years. Besides all this the innovative ideas that I am currently working on in my “spare time ” which has become the most valuable time due to constraints of the methodologies (1) Self Assessment, (2) Career Exploration, (3) Career Identification, and (4) Action Plan. However the reality is the common denominator in all these elements is time. Once societies understand the challenges of the world as they apear in time, governments would be forced to invest in their academics so that we can procure innovative ideas and new industries that are well overdue.
The subject of PhD is part of my academic dream and one I will go after as long as I am alive.
Engineers are problem solvers in what ever context you wanna put it. So with so many problems in the world its just not sustainable for our societies to keep up with the rapid changes. The methodology of the current systems and there inefficiencies clearly need a overhaul. We live in a information age and soon to be a metaverse world which will open up new pathway plans for better service delivery to the community creating global scaled solutions. The effectiveness of the value of time can always be questionable and improved.
