Why Study @ Swinburne CAS?

Because we're focussed on research!

Excellent researchers, cutting-edge astrophysics
With around 20 research faculty, 20 postdoctoral researchers and 30 PhD students from over two dozen different countries, CAS offers a vibrant, diverse and research-focused atmosphere where PhD students help conduct – and learn how to lead – cutting-edge research. As the home of the ARC Centre of Excellence for Gravitational Wave Discovery, OzGrav, and also a node of the ARC Centre of Excellence for All Sky Astrophysics in 3D CAS is one of Australia's leading astronomy and astrophysics research centres.

Wide-ranging expertise
With expertise in optical, infrared and radio astronomy, computational and theoretical astrophysics, we observe, imagine and simulate the most exciting astrophysical phenomena. Our research strengths cover all major areas of astronomy, from cosmology and the large-scale structure of the Universe, to quasars and the most distant known galaxies, extreme phenomena (including supernovae, hypernovae, fast radio bursts, and gravitational waves), to clusters and groups of galaxies, down to our own Milky Way, its structure and fascinating contents: stars, planets, pulsars, neutron stars and globular clusters. We also research 3-D visualisation techniques and applications of advanced scientific computing. Our latest research results are highlighted in our news section.

The world's best telescopes
We are the only Australian institute to have access to the Keck twin 10-metre telescopes! The Keck Observatory in Hawaii comprises the world's largest optical telescopes and CAS astronomers are now observing there for 15 nights per year. You could too! And with access to European Southern Observatory facilities including the Very Large Telescope, thanks to Australia's 10 year Strategic Partnership with ESO. CAS astronomers are also regularly awarded observing time at major national, international and space-based observatories covering the entire electromagnetic spectrum.

Extreme computing
CAS is also home to 'The Green Machine' and the GPU-based 'gSTAR', and since March 2018 also the new 'OzSTAR' supercomputer. As some of Australia's most powerful supercomputers, these facilities are excellent research tools in key areas of astronomy ranging from simulations of large-scale structure formation to the processing of enormous data volumes collected from radio telescopes. They are also used to render 3-D animations and movies promoting and explaining astronomy to the broader community. CAS is the only astronomy department in the southern hemisphere with its own supercomputers.

High-achieving PhD students
Around 30 high-achieving students are currently undertaking their PhD studies at CAS. They are a friendly, knowledgable group of independent-minded astronomers who help each other become experts in their fields. CAS students come from all over the world, not just Australia: as the map indicates, current CAS students come from more than two dozen different countries. They speak about 20 different languages fluently.

We encourage applications from high-achieving students anywhere in the world who are strongly motivated to complete a PhD in astrophysics and/or supercomputing with an emphasis on astrophysical applications.

We welcome and encourage visits to CAS by prospective PhD students! It's the best way for you to see who we are, what we do and what doing a PhD here is all about. Please contact Dr. Edward Taylor by phone or email to arrange a visit.

The CAS PhD Program

The primary postgraduate degree we offer is a Doctor of Philosophy (PhD) by Research in Astrophysics. Academically high-achieving students work with leading astronomers to research important questions in astrophysics, data analysis and visualization. The 3.5 year program enables students to conduct independent research at a high level of originality, relevance and quality. Swinburne PhD graduates often take positions in leading astrophysics institutions around the world, and pursue a diverse range of other careers.

A wide range of potential PhD topics are on offer. Summaries of current thesis work by CAS students are also available.

CAS PhD students are provided with a powerful workstation and access to the considerable computational resources of 'The Green Machine' and 'gSTAR'. Students have access to internal funding to help support travel to telescopes, international conferences and/or collaborative meetings. Please see the summary of PhD student support at CAS.

CAS maintains links with astronomers at the Australian Astronomical Observatory and the Australia Telescope National Facility. Potential PhD projects on offer at the AAO and ATNF are also available to incoming Swinburne students. CAS PhD students also have numerous opportunities to be involved in outreach and education.

Swinburne Research administers all of the University's research and graduate studies. For more information, see their Post-graduate Studies website. The full Research Degrees Policies and Guidelines can be found there. Please note that we do not offer PhD programs online or by distance learning.

Masters by Research

Formally, we do award Masters by Research degrees in Astrophysics, but this is not the preferred route for postgraduate study at CAS. Scholarships for Masters by Research applicants are almost never awarded. If you believe your situation is exceptional, please contact Dr. Edward Taylor by phone or email to discuss your case.

Please note that we do not offer Masters by Research programs online or by distance learning. CAS does offer an online Master of Science (Astronomy) course via Swinburne Astronomy Online, but this is not a research degree.


Note for international students: there are significant costs associated with moving to Australia to start a PhD, including Overseas Student Health Coverage, visa and relocation expenses. Please find some information about these costs, and our sources of PhD student support, at this link.

At CAS we normally only accept PhD students who receive a scholarship to support them during their studies. Fortunately, Swinburne offers a range of different scholarships (see here for the latest rates) for both international and domestic students (typically SUPRA and RTPS scholarships respectively). All scholarships include a tuition-fee waiver.

We call for Expressions of Interest in our PhD program once or twice per year. See below for instructions on How To Apply. All PhD scholarships are highly competitive, so CAS first assesses the qualifications of each candidate.

Note: External scholarships. Some countries and external agencies offer scholarships for students wanting to study a PhD in Australia. We encourage students to apply for these opportunities in addition to applying for a scholarship from Swinburne; students applying for external scholarships still need to complete the stages listed in the How To Apply section below.

How To Apply

Applications for PhD positions and scholarships at CAS proceed in four stages:

  1. An online Expression of Interest (EoI) to CAS.

    Next deadline TBA; second half of 2018.

  2. If your application is short-listed following the EoI deadline, discussions with potential CAS PhD supervisors.
  3. A short, formal interview with representatives from CAS, either in person, skype or phone.
  4. A formal application to Swinburne for PhD candidature and a scholarship.

These four stages are described in more detail below. Typically, students start their PhD around 6 months after the EoI deadline, although their is flexibility in the start date.

Expression of Interest (EoI)

As a first step, all students interested in undertaking a PhD in CAS must submit an Expression of Interest (EoI) via our online system. We happily accept and review expressions of interest submitted outside of our regular recruitment rounds. You will be asked to upload documents such as your CV, academic transcripts, examples of previous research, and nominate academic references. Our selection panel will shortlist the best candidates who have a good chance of obtaining a PhD scholarship at Swinburne. The selection panel will notify shortlisted candidates about 2 weeks after the EoI deadline.

Finding a supervisor

If your EoI is shortlisted by the selection panel, you will be invited to start searching for a PhD supervisor and discussing potential PhD projects with CAS staff.


After matching with supervisors, we interview all CAS scholarship applicants to assist us and Swinburne in fairly and accurately ranking them. Such interviews are normally held by skype, phone or in person about a month after the EoI deadline.

Formal Applications

Once a CAS staff member agrees to supervise your PhD studies, you've agreed on a PhD project, and have passed the interview, you will prepare a formal application to Swinburne for PhD candidature and a scholarship.

Timing of applications and PhD start dates

Scholarship winners are informed about 1 month after the EoI deadline. The formal application process, to issue the Confirmation of Enrolment at Swinburne, can take several weeks. Students requiring a visa to study in Australia may then apply for one, taking typically 1 month, and then make arrangements to travel to Melbourne to begin their PhD studies. After these steps, students typically begin their PhDs in CAS around 6 months after the EoI deadline, although there is a wide variation (3-9 months).


The eligibility requirements for undertaking a PhD at CAS are detailed in Swinburne Research's Research Higher Degrees Policy and Procedure document. In summary, PhD applicants must have completed at least 4 years (or part-time equivalent) of university studies, at a high level of achievement, in a subject area related to their proposed PhD project. For most CAS PhD applicants, this translates to having completed a BSc with first or upper second class Honours or a Masters (with a research component) awarded at a similarly high grade.

IMPORTANT: There are also English language requirements for international students.

If English is not one of your native languages then at least 24 full months (or part-time equivalent) of your formal university studies must have had English as the language of instruction and assessment.

If that is not the case, you must submit the results of an English language examination with any formal PhD scholarship application. You do not have to take such exams before submitting an EoI.

If you have previously taken a language exam, the results must have been issued no more than 2 years prior to your application.

International students must study full time.
