Preparing for a Viva Voce Examination at an Australian University

Prof. David Chen · 2025-01-15 · 7 min read · PhD

While less common than in the UK, some Australian universities require an oral examination. Here's how to prepare.

Introduction

While Australian PhD examination is primarily thesis-based (unlike the UK, where a viva voce is standard), some Australian universities and disciplines do require or offer an oral examination. Understanding what to expect can help you prepare effectively.

When Is a Viva Required in Australia?

Universities That May Require It

Some Australian universities include an oral component as part of the examination process:

  • University of Western Australia (for some disciplines)
  • Some faculties at Monash University
  • Creative arts and practice-based PhDs at various universities
  • Professional doctorates (DBA, EdD) at some institutions

    • When It's Optional

    Some universities offer an optional oral examination:

  • To clarify issues raised by examiners
  • When examiners' reports are contradictory
  • When the candidate requests one

    • When It's Not Used

    Most Australian PhD examinations rely solely on written examiner reports. The thesis speaks for itself.

    Types of Oral Examination

    Thesis Defence

    A formal presentation and questioning session, similar to the UK/European viva:

  • 30–60 minute presentation
  • 60–90 minutes of questions from a panel
  • Panel may include external examiners, internal academics, and an independent chair

    • Oral Clarification

    A less formal session to address specific questions raised by examiners:

  • Usually shorter (30–60 minutes)
  • Focused on specific issues in the examiner reports
  • May be conducted via video conference

    • Research Presentation

    Some programs require a public research presentation:

  • Open to the university community
  • Followed by questions from the audience and panel
  • Common in sciences and engineering

    • How to Prepare

    Know Your Thesis Inside Out

  • Re-read your entire thesis before the examination
  • Be prepared to discuss any section in detail
  • Know the limitations of your research and how you'd address them
  • Understand how your work contributes to the broader field

    • Anticipate Questions

    Common viva questions include:

    **About Your Research:**

  • "Can you summarise your thesis in 3–5 minutes?"
  • "What is the original contribution of your research?"
  • "If you could do it again, what would you change?"
  • "What are the main limitations of your study?"

    • **About Methodology:**

  • "Why did you choose this methodology over alternatives?"
  • "How did you ensure the reliability/validity of your findings?"
  • "How generalisable are your results?"

    • **About the Field:**

  • "How does your work relate to [specific scholar's] research?"
  • "What are the implications of your findings for practice/policy?"
  • "Where do you see this research going in the next 5–10 years?"

    • Practice

  • Present to your supervisor and ask them to challenge you
  • Practice with peers — they'll ask different questions
  • Record yourself and review
  • Prepare concise, structured answers (don't ramble)

    • Practical Preparation

  • Bring a copy of your thesis (annotated with key page numbers)
  • Dress professionally but comfortably
  • Arrive early to settle your nerves
  • Bring water and any notes you need

    • During the Examination

    Presentation Tips

  • Structure your presentation clearly (introduction, methods, key findings, contribution)
  • Use slides sparingly — focus on key figures and results
  • Don't try to cover everything — highlight the most important aspects
  • Stick to the time limit

    • Answering Questions

  • Listen carefully to the full question before answering
  • It's acceptable to pause and think before responding
  • If you don't understand a question, ask for clarification
  • Be honest about limitations — examiners respect intellectual honesty
  • If you don't know the answer, say so — then explain how you'd find out

    • Managing Nerves

  • Take deep breaths before and during the examination
  • Remember: you know more about your research than anyone else in the room
  • The panel wants you to succeed — they're not trying to trip you up
  • Most candidates pass — the viva is rarely the deciding factor

    • After the Examination

    The panel will typically deliberate and provide one of the following outcomes:

  • Pass with no amendments
  • Pass with minor amendments (most common)
  • Major amendments required
  • Revise and resubmit

    • You'll receive formal written feedback, usually within a few weeks.

    Conclusion

    Whether required or optional, an oral examination is an opportunity to showcase your expertise and passion for your research. With thorough preparation, it can even be an enjoyable experience. DissertlyPro can help you prepare for your viva with mock examinations and presentation coaching.
