Academic writing has long been associated with detached, formal sentences, and the passive voice has carried much of that reputation. Phrases such as "it has been argued" or "the data were collected" sound scholarly, yet they often hide who did what. Across universities in Sydney, Melbourne, Brisbane and Perth, markers often return drafts with the same note: tighten the prose. Shifting towards active constructions is one of the most reliable ways to do that.
Active voice places the doer of the action at the front of the sentence, followed by the verb, then the object. The result is tighter syntax, shorter sentences, and a clearer sense of responsibility. For students writing under the academic integrity frameworks monitored by bodies such as the Tertiary Education Quality and Standards Agency, clarity about who performed an action is more than a stylistic preference. It reinforces accountability, which sits at the heart of scholarly ethics and is closely linked to practices covered in guidance on understanding plagiarism.
There is, however, no rule that every sentence must be active. Skilled academic writers know that passive voice remains useful when the actor is unknown, unimportant, or less interesting than the action itself. The skill lies in choosing deliberately rather than defaulting. Reading sample papers from the essay examples library shows how experienced writers switch between voices depending on the discipline, the audience, and the conventions of the journal or department.
What follows is a practical guide for Australian students who want to sharpen their academic prose. It covers how to recognise passive constructions, when to keep them, and how to build a habit of writing with cleaner, more confident sentences that still respect the formality expected in Australian universities.
Passive voice usually hides inside a recognisable shape: a form of "to be" followed by a past participle. Sentences like "the survey was administered" or "the findings were discussed" should raise a small flag. The pattern almost always signals that the writer could have named an actor and chosen a stronger verb instead. A quick search for "was," "is," "were," "been," and "being" highlights many candidates, though not every match is passive — sometimes those auxiliaries are doing other grammatical work.
A second clue is vagueness. When a sentence reads smoothly but leaves the reader wondering who actually carried out the action, the construction is often passive. In Australian theses examined under the conventions of institutions such as the University of Queensland, the Australian National University, or Monash, examiners regularly flag this vagueness as a weakness, particularly in methodology chapters where precision is essential.
It helps to read each paragraph aloud. Active voice tends to land with a confident rhythm, while passive voice often feels padded, especially when paired with nominalisations such as "the analysis was performed by the researcher." Listening for that heaviness is a quick way to find sentences that could be rewritten with the actor restored.
The differences between the two voices become clearer when placed side by side. Common academic constructions appear below alongside revised versions, with a brief note on the effect of each change. The revisions are minor in some cases and substantial in others, but every rewrite preserves the original meaning while making the actor visible. Many students find this kind of comparison useful as a template they can apply to their own drafts.
| Passive sentence | Active revision | Effect |
|---|---|---|
| The samples were analysed by the research team using gas chromatography. | The research team analysed the samples using gas chromatography. | Names the actor and shortens the sentence by removing the auxiliary. |
| It is widely believed that policy reform is overdue. | Many scholars argue that policy reform is overdue. | Replaces vague attribution with a specific type of source. |
| The experiment was conducted over a six-week period. | We conducted the experiment over a six-week period. | Establishes first-person ownership where appropriate. |
| A limitation was identified regarding the small sample size. | The small sample size limits the generalisation of the findings. | Shifts from reporting a vague event to making a direct claim. |
| The results have been interpreted in several ways. | Researchers have interpreted the results in several ways. | Identifies the interpreters, which adds credibility. |
These swaps are not about stripping formality. Australian academic English still allows for measured prose, including British spelling conventions such as "behaviour," "analyse," and "recognise" used across most universities. Active voice simply delivers the same content more efficiently, letting readers absorb the argument with less effort.
When rewriting a passive sentence, the first decision is what to make the subject. Often the actor is already implied in the surrounding text — the writer, the research team, the policy makers, or the participants. Putting that actor up front gives readers a clearer map. In a literature review, for example, "Brown (2021) argued that..." is more informative than "it has been argued that..."
Sometimes the subject is not a person but a piece of evidence or a study. Sentences like "the dataset revealed a clear pattern" are active even though no human actor is named. This is a useful pattern when the writer wants to emphasise what the data does rather than who collected it, a common move in chapters reporting findings from ARC-funded research projects in Australia.
The subject should be specific enough to do real work. "Researchers have found" carries more weight than "it has been found," and "the survey indicates" is sharper than "indications were made." Each tightening gives the reader something to anchor onto across several pages of dense prose.
A common worry is that active voice sounds too direct or personal for academic writing. In Australian tertiary contexts, where group work, lab reports, and reflective journals are routine, students sometimes fear that "I" or "we" will sound informal. Academic style guides, including the APA and Harvard variants taught in most Australian universities, accept first-person usage where it aids clarity.
Where the actor truly is the author — in a methods chapter, a reflective essay, or a position paper — first-person active voice is both appropriate and clearer. Phrases such as "we interviewed twenty participants in Melbourne" or "I reviewed the literature between February and June" give readers honest information about how the work was done. Compare that with "twenty participants were interviewed," which hides the researcher's role.
When the actor is a third party, the same principle applies. "The High Court ruled in 1992 that..." reads more naturally than "a ruling was made in 1992 that..." Active attribution also helps writers comply with the citation standards expected under Australian academic integrity policies, which require clear sourcing of claims.
Active voice is the default, but passive constructions remain useful in specific situations. Scientific writing about procedures often calls for passive voice when the method is more important than who performed it. Protocols and lab manuals across CSIRO publications and university science faculties describe actions without naming the actor, since the focus is on reproducibility.
Passive voice is also appropriate when the actor is genuinely unknown or deliberately omitted for ethical reasons. In qualitative research involving sensitive populations — a common scenario in studies approved by human ethics committees in Adelaide, Hobart, and elsewhere — researchers may write "participants were interviewed" rather than identify individuals. Here the passive voice protects anonymity and aligns with ethical clearance conditions.
Passive voice can also smooth transitions. When a paragraph focuses on a single topic and the actor stays the same for several sentences, occasional passive phrasing avoids repetitive subject-verb openings. The skill is using this sparingly and with intent, rather than letting it dominate.
Improving active voice use is less about rules than about routine. Reserve the last ten or fifteen minutes of every writing session for a focused pass over each paragraph. During that pass, the writer scans for "was," "is," "were," "been," and "being," then rewrites any passive sentence that hides a meaningful actor. This editing sprint works well alongside the study habits common among Australian undergraduates, from the reading rooms of the State Library of Victoria to the late-night study spaces of the University of Sydney.
A second routine involves keeping a personal log of rewrites. Every time a sentence becomes stronger after being switched to active voice, the writer notes the original and the revision. Over a semester, this log becomes a record of the writer's own voice, useful when revising future drafts.
A third routine is reading published work in the target discipline with the voice in mind. Noticing how experienced writers in journals from across the Group of Eight handle active and passive constructions builds an intuitive sense of what works in a particular field. Combined with patient editing, that intuition becomes the foundation of clearer, stronger academic prose.
