The Australian National Dictionary Centre at ANU chose "social media ban" as its 2025 Word of the Year. Macquarie Dictionary chose "AI slop". Neither will help you at a Coles checkout at 6pm on your third day here.
A much smaller set of words will. Maybe forty do almost all the work in a first month: the ones you hear from a housemate, a shift supervisor, a leasing agent, and a lecturer who says "yeah nah" in a way that sounds like agreement and is not.
Most slang lists are written for tourists, full of words nobody under sixty says out loud. This one is organised by the situation you are standing in when you hear the word, and it prioritises the ones that confuse, embarrass or cost you money.
Casual vocabulary is low stakes. The vocabulary of renting, enrolment and casual work is not slang at all, but it is unfamiliar enough to function like it, and getting "census date" wrong is more expensive than getting "bikkie" wrong.

The pattern behind half the list
Australian English shortens a word to one syllable and adds either -o or -ie. Afternoon becomes arvo, service station becomes servo, breakfast becomes brekkie, sunglasses become sunnies. The Australian National Dictionary Centre dates arvo to the 1920s, so this is a century old habit, not an internet one.
So if you hear a short word ending in -o or -ie that you do not know, guess the long form. Rego is registration, ambo is an ambulance officer, garbo is the rubbish collector. You will be right more often than not.
Two you cannot guess. Maccas is McDonald's. Colesworth is a joke compound of Coles and Woolworths, used when someone is complaining about grocery prices.
At the shops and the checkout
A checkout worker will say "how are you going?" This is not a question about your journey or your wellbeing. It is hello. Reply "good thanks, how are you?" and the transaction proceeds.
You may also get "you right there?" while browsing. That means "do you need help?" The answer is "yeah I'm right thanks", which means no.
When you thank someone, expect "no worries", "you're right" or "all good" in return. All three mean you are welcome, and none imply there was a problem.
"Chemist" is the pharmacy. "Bottle-o" is the liquor shop, a separate licensed shop here rather than a supermarket aisle.
At uni and in class
The vocabulary here is half slang and half administration, and the administration half matters more.
Australians say "uni", never "college". Here a college is usually a residential hall or a vocational provider, so saying you go to college produces a follow up question.
A "unit" or "subject" is what you might call a course. A "course" is the whole degree. "Semester" is the standard half year block, though some providers run trimesters, three shorter teaching periods a year that compress your workload.
The word that costs money is census date. The University of Sydney defines it as "the date when your enrolment in your unit of study is finalised and you become academically and financially liable". Drop a subject before it and you owe nothing. Drop it after and you are charged, and international students may only be allowed to withdraw for circumstances beyond their control. Put the date in your phone in week one.
"Tute" is tutorial, "prac" is practical class, "wag" means to skip a class. "Reckon" means think, and it is normal in seminars: "I reckon the second reading is stronger."
The housing options open to first year international students differ a lot in how far they sit from a 9am tute.
At a share house inspection or with an agent
This is where misunderstanding costs money.
Bond is the security deposit. In Victoria, Tenants Victoria states the maximum is one month's rent where the rent is $900 a week or less, and the Residential Tenancies Bond Authority holds it, not the landlord. That is the point students miss: bond is lodged with a state authority, so if an agent asks you to pay it into a personal account, stop.
An "inspection" has two unrelated meanings. A pre lease inspection is the open house where twenty people walk through in fifteen minutes. A routine inspection is the landlord's periodic check once you live there, with written notice. If a housemate says "we've got an inspection Thursday", ask which kind.
A "lease break" is ending a fixed term agreement early, and it usually costs you advertising, reletting fees and rent until a new tenant starts. See what breaking a student accommodation contract early actually costs.
"Furnished" often means a bed and a wardrobe, not cutlery. "Bills included" needs a definition in writing. "Doona" is the quilt you buy on day two, because it is rarely supplied.
"Agent" means the property manager acting for the owner, not for you. The differences between PBSA and a private rental matter more here than the slang, and your rights as a student tenant are worth reading before you sign. Scam listings exploit this vocabulary gap with terms like "holding deposit" that sound official and are not.
At work in a casual job
Casual and part time are different legal categories, not two words for the same thing.
A casual has no guaranteed hours and no paid annual or sick leave, and is compensated with a loading. The Fair Work Ombudsman states that from 1 July 2026 the national minimum wage is $26.44 an hour, and casuals entitled to it must get at least $33.05 an hour, including the 25 per cent casual loading. A part time employee has set hours and paid leave.
"Penalty rates" are the higher rates paid for evenings, weekends and public holidays under an award. If your Sunday rate matches your Tuesday rate, ask which award covers you.
"Super" is superannuation, the compulsory retirement contribution your employer pays on top of your wage, set by the ATO at 12 per cent of ordinary time earnings for 2025 to 2026. It is not a deduction from your pay, and casuals get it too. International students can generally claim it when they leave Australia permanently.
"Cash in hand" means unrecorded payment. It strips you of super, penalty rates, records for your visa and any ability to complain.
Other shift words: "roster" is the schedule, "shout" means to buy a round, "knock off" means finish work, "sickie" means a day off claimed as sick.
At the doctor
A GP is a general practitioner, your first stop for anything non urgent. "Bulk billing" means the clinic charges Medicare directly and you pay nothing, but most international students are not on Medicare, so expect to pay and claim back. Overseas Student Health Cover is a visa condition, and the government's privatehealth.gov.au notes it covers hospital, medical and ambulance care plus limited pharmaceuticals, but not dental, optical or physiotherapy. "Script" means prescription, and 000 is the emergency number.
At the pub, socially, and on public transport
"Yeah nah" and "nah yeah" are the two most misread phrases in Australian English, and they are not random.
The final word carries the meaning. "Yeah nah" means no, softened by acknowledging what you said. "Nah yeah" means yes, after brief hesitation. "Yeah nah yeah" means yes. If you cannot follow the chain, listen for the last syllable.
"Heaps" is the general intensifier: heaps good, thanks heaps. "Keen" means willing, so "are you keen?" is an invitation. "Carry on" means to make a fuss, not to continue. "She'll be right" means it will work out, and is sometimes a real assessment and sometimes a way of avoiding one.
The transport card is regional: Opal in Sydney, Myki in Melbourne, go card in Brisbane. Most systems require a tap on and a tap off, and forgetting to tap off charges the default fare. Concession fares vary by state and are not automatic for international students.
A "sanger" is a sandwich, a "snag" a sausage, and "bring a plate" means bring food to share.
Mate, insults, and the tone rule
Australians use words as friendly address that are insults elsewhere. This is real, and it is also the area where a new arrival is most likely to misjudge.
"Mate" is the clearest example. Said warmly it means friend, and strangers use it constantly. Said flatly, slowly, with a pause before it, it is a warning. The word has not changed. Tone did all the work.
Beyond that, some Australians address close friends with words that are genuinely offensive in most other Englishes, and treat the offensiveness as proof of intimacy. Two rules keep you safe. Receiving one of those words from a friend is usually affectionate, and reacting calmly costs you nothing. Do not use them yourself until you have heard that person use them about themselves, and never at work or in class.
The workplace line is firm regardless of what you hear on a building site. Australian employers are subject to discrimination and bullying law, and "everyone talks like that" is not a defence. Universities apply their own conduct codes. Swearing casually among friends is normal here. Swearing at someone, or about a protected attribute, is not.
This register is easier to receive than to produce, and you lose nothing by understanding it without using it.
The words the lists include that nobody says
Be sceptical of any slang list that features these.
"Strewth", "crikey", "fair dinkum" as an exclamation, "shrimp on the barbie" (Australians say prawn), "sheila" for a woman, "cobber" for friend, and "g'day mate" as tourism advertising uses it. You will hear "g'day" in regional areas, but the full stage version is rare.
"Bogan" is real and current, but handle it carefully. It is a class judgement, defined by the Australian National Dictionary Centre as an uncultured or unsophisticated person, and it spread after a late 1980s television character. Australians use it about themselves freely. A recent arrival using it about a suburb lands differently.
Regional variation is genuine. The Macquarie Dictionary's Australian Word Map divides the country into 27 regions and collects words that work in only some of them, including the words for a sausage in bread and a swimming costume. A national slang list is always slightly wrong wherever you are.
Frequently asked questions
What does "yeah nah" mean in Australian slang?
It means no. The last word carries the decision, and the first is a politeness acknowledging what you said. "Nah yeah" reverses it and means yes. In a longer chain, the final syllable is the answer.
Why do Australians say "how are you going" instead of hello?
It is a greeting, not a question, and has nothing to do with travel. Reply "good thanks, how are you?" and continue. "How ya going" and "how's it going" work identically.
Are thongs shoes or underwear in Australia?
Shoes. Thongs are the flat rubber sandals sold everywhere for a few dollars, and the word is used without hesitation on campus and at work. For the underwear, Australians say g-string.
Is it rude if an Australian friend swears at me?
Usually not, if the tone is warm and it is aimed at the situation or used as address. Australians often use offensive words affectionately with close friends. Do not copy it until you know the person well, and never at work or in class.
What is the difference between casual and part time work in Australia?
Casual work has no guaranteed hours and no paid annual or sick leave, and is paid a loading instead. From 1 July 2026 a casual on the national minimum wage must receive at least $33.05 an hour, including the 25 per cent loading. Part time work has set hours and paid leave.
What is a census date and why does it matter?
It is the date your enrolment in a subject is finalised and you become financially and academically liable. Withdraw before it and you owe nothing. Withdraw after and you are charged, and international students may face extra restrictions and fees.
Bottom line
Learn the twenty words in the table plus bond, lease, census date, casual loading and super. The rest you will absorb by accident within a month, and performing it early is the fastest way to sound like a tourism brochure.
The real risk is not misusing "arvo". It is nodding through a leasing conversation or a first shift because the words sounded approximately familiar and you did not want to interrupt. Australians are largely unbothered by being asked to repeat themselves.
Slang varies by state, suburb and age, so treat any list, including this one, as a starting point rather than a script. Our guides to the types of student housing available in Australia and the journey from arrival to move in cover the decisions that come first.
