Closing the same ICT gap with a graduate diploma or a master's: what ACS measures, and what the extra year buys

For the purpose that most people are actually asking about — getting an Australian postgraduate ICT qualification that the Australian Computer Society will treat as having a computing major — the award name does not decide anything. ACS says so in one sentence, and puts both awards inside it.

What does decide things is arithmetic: how long the qualification runs, how many units it contains, and what proportion of it is ICT. Those numbers are published, they differ sharply between a graduate diploma and a master’s at the same university, and they are the numbers to check on a course page before you pay for it.

This page reports ACS’s published criteria and figures from four university course pages, all read on 3 September 2026. It is not ACS, it does not assess qualifications, and it does not predict any assessment outcome.

The rule, in ACS’s words

On its qualifications evidence page, ACS sets out how it decides whether a qualification has an ICT major. For the postgraduate level:

“A 2-year postgraduate qualification (such as Graduate Diploma or Masters) is deemed as having a major in computing if at least 50% of the qualification is ICT.”

Note the parenthesis. Graduate diploma and master’s are named together, inside the same rule, with the same threshold. There is no separate, weaker test for a diploma and no bonus for a master’s.

The same page then adds three specific minimums, and this is where the two awards start to come apart. Australian postgraduate qualifications, ACS says, must contain:

“A minimum of 3 semesters or at least 1.5 years of full-time study; At least 2 semesters or 1 year of full-time equivalent ICT content; A minimum of 12 units or subjects”

And a further condition for compact Australian degrees: “An Australian postgraduate degree with only 12 subjects requires at least 67% ICT content.”

Three thresholds, then, that a course page will tell you about directly: 1.5 years full-time minimum, 12 units minimum, and an ICT proportion of at least half — rising to two-thirds if the qualification is exactly twelve subjects long.

Two further rules sit behind those and are worth knowing before you choose electives.

An IT minor is defined relationally: “A Bachelor’s or higher qualification is assessed as a minor when the IT content is at least two-thirds of the requirements for a major.” Anything below that is assessed as a non-IT qualification.

And the ICT content has to be the right ICT content: “In all educational qualifications, at least 65% of the IT content must be closely related with sufficient core content to the nominated occupation (ANZSCO) to meet the suitability criteria.” A qualification can clear the major threshold and still fail this one, because they measure different things — volume, then relevance to one nominated occupation.

We cover how the major test is applied in what counts as an ICT major under ACS, and the case of adding ICT at postgraduate level on top of a non-ICT bachelor’s in non-ICT bachelor’s plus ICT master’s.

Two gates, not one — and universities advertise the other one

There is a second thing called “ACS accreditation”, and it is not the same as the assessment above.

ACS runs an accreditation scheme for ICT degree courses, and describes itself on that page as “the official accrediting body for ICT degree courses in Australia”, with a scheme aligned to the AQF, the Higher Education Standards Framework and the international Seoul Accord. Universities advertise that accreditation on their course pages, and it is the thing most prospective students think they are checking.

ACS itself is careful about how the two gates relate. On the assessment side it says: “Australian qualifications that have been accredited by the ACS will generally meet the IT, Data Science or Cyber Security major criteria. Please note that this does not guarantee that the qualification will be assessed as being closely related to the nominated occupation and ANZSCO code.”

So course accreditation is a strong signal about the first test and says nothing about the second. Choosing an accredited course does not remove the need to look at whether its ICT content is closely related to the occupation you intend to nominate.

Two practical notes on checking accreditation, both from the list itself.

Accreditation is dated, and the dates are ranges. Every row on the ACS list carries an “Accreditation Period” written as a year range — we saw periods such as 2026–2028 and 2018–2025 on the list on 3 September 2026. Accreditation attaches to intake years, not to institutions in perpetuity. The row that matters is the one covering the year you commence.

Award titles on the list and on marketing pages do not always match. The ACS list is organised by institution and school and uses the award title as ACS records it, which is not always the title a university markets. Matching by name alone will produce false negatives. If you cannot find your course, that is a question for ACS or the provider, not a conclusion.

We are not going to tell you which specific awards are or are not accredited. We will say what we observed about the list’s shape when we read it: every award title on it was a Bachelor-level or Master-level award. We did not find a graduate certificate on it, and we found a single graduate diploma. Draw no inference from that about any particular course — ACS’s own accreditation criteria documents sit under a path its robots.txt closes to crawlers, so we did not retrieve them and cannot tell you what the scheme’s scope rules say. Ask ACS.

The same gap, two ways: what the numbers look like

Here is the comparison the question is really about, using two universities that publish both awards and their figures. All figures are as published by the institution on 3 September 2026, are indicative, and are subject to the caveats each institution attaches.

At UNSW, the Graduate Diploma in Information Technology runs 1.7 years full-time and carries 72 units of credit. The Master of Information Technology runs 2 years and carries 96 units of credit. The 2026 indicative international first-year fee is the same on both pages, at $63,000; the indicative fee to complete is $97,000 for the diploma and $130,500 for the master’s. On the Commonwealth Supported Place figures, the indicative fee to complete is $14,500 for the diploma and $19,000 for the master’s. The master’s page states: “This program is accredited with the Australian Computer Society at the level of Professional.”

At Southern Cross University, the Graduate Diploma of Information Technology runs 1 year full-time and requires 8 units; the Master of Information Technology runs 2 years. Both pages quote an indicative annual international fee of $26,000, which the fee table breaks down as $3,250 per unit and states is “based on completing 8 units per year”. The graduate diploma page states “This course is accredited by the Australian Computer Society (ACS)”; the master’s page states the program “is professionally accredited by the Australian Computer Society (ACS)”.

Read those two universities side by side and the useful lesson is not which is cheaper. It is that “graduate diploma” is not a fixed quantity. One of these runs 1.7 years and 72 credit points. The other runs 1 year and 8 units. They carry the same award name and are not the same thing, and ACS’s thresholds — 1.5 years, 12 units — are set in exactly the units that separate them.

Do the arithmetic against your own course page before you enrol. Only ACS can say what it will decide about any particular qualification, and nothing here is a prediction about either of these courses or any other.

What the extra year actually buys, honestly

Three things, and it is worth being clear which of them you are paying for.

Headroom against the thresholds. A longer, larger qualification is further from every published minimum. That is the whole of it — being further above a threshold does not earn anything extra, it just removes a way to fall short.

A higher AQF level. ACS assesses postgraduate qualifications “to the equivalent of a 2-year AQF Level 8 and above award”. A master’s and a graduate diploma are different AQF levels, which can matter for things that are not ACS assessments at all — admission to further study, some employers’ classification structures, and some overseas recognition processes.

Optionality, if the credit works. Southern Cross states that “Graduates of the Graduate Diploma receive direct entry and up to eight units of credit towards the Master of Information Technology”, and describes the diploma as “a pathway to further postgraduate study”. Where a provider publishes articulation like that, doing the diploma first is not a cheaper route to the master’s — the units are the same units — but it is a way of committing to half of it at a time. That has real value if you are unsure, and none at all if you already know you want the master’s.

What the extra year does not buy is a different test. The same 50% ICT rule, the same 65% closely-related rule, and the same nominated-occupation requirement apply to both.

The scheduling trap nobody puts on the price page

UNSW’s course pages carry a notice that its academic calendar changes from 2028, and that “the duration of your studies may vary depending on when you commence your degree prior to 2028”. Its international admissions notice adds that some programs were at capacity for 2026 intakes with applications closed to new overseas commencements, while 2027 intakes were open.

A published duration is a statement about a structure, not a promise about your calendar. Where a duration is expressed as 1.7 years, ask how that maps onto actual terms and start dates in the year you would commence, because a qualification that ACS measures in semesters and years is one where a few months of calendar slippage can move you across a threshold.

What this page does not do

It does not assess your qualification and does not tell you whether ACS will find an ICT major, a minor, or neither. ACS decides that, on a complete application, against the criteria in force when you apply.

It does not name any institution or course as unaccredited, and nothing here should be read that way. Where we describe the ACS list, we describe only what appeared on it on one dated reading.

It does not reproduce the ACS accredited-courses list. Read ACS’s own list for the accreditation period covering your intake year.

It does not quote a fee we did not read on the institution’s own page, and every fee above is indicative and dated. Fees change annually; check the figure for your commencing year.

It does not cover visas, points, or nomination. A skills assessment is not an immigration decision and this site does not give immigration advice; for that go to the Department of Home Affairs or a registered migration agent.
