18 Australian Slang Words You Need to Know in 2025
1. G’day
A contraction of “Good day,” this greeting is so embedded in Aussie life that you’ll hear it at dawn, midday, and dusk. It dropped the first vowel sound and added that relaxed apostrophe, making “G’day” the go-to opener in cafés, shops, and streets.
While outsiders might think it’s reserved for friends, Aussies use it politely with strangers, too, no class barriers here.
Example: “G’day! Could I grab a flat white, please?”
2. Mate
More than just “friend,” “mate” reflects Australia’s egalitarian culture. It’s a term of camaraderie and respect, cutting through social hierarchies.
You’ll hear it in both city boardrooms and rural paddocks. Calling someone “mate” softens requests, builds rapport, and, when used with strangers, signals you want to connect on friendly terms.
Example: “Thanks for lending me your umbrella, mate.”
3. No worries
Literally translating to “don’t worry,” this phrase is Australia’s answer to “you’re welcome,” “it’s okay,” and “no problem.” It embodies the relaxed attitude Aussies take toward mishaps or favours.
Someone thanks you? You reply “no worries.” You oversleep? A mate tells you “no worries.” It’s versatile, polite, and reassuring, all in two words.
Example: “Cheers for picking me up.” “No worries!”
4. Fair dinkum
When authenticity matters, Aussies pull out “fair dinkum.” It means genuine, honest, or the real deal. You can call a person fair dinkum (trustworthy), an offer or story fair dinkum (credible), or even a situation fair dinkum (serious).
The phrase likely traces back to British dialect “dinkum” (meaning honest work or wages), which Aussies grafted “fair” onto for emphasis by the late 1800s.
Example: “Is that car up for grabs, or are you just yanking my chain?” “Fair dinkum, it’s yours for a good price.”

5. Crook
When Aussies say they feel “crook,” they’re talking about being unwell, anything from a mild cold to a full-blown flu. The term goes back to the early 20th century and echoes the British use of “to crook” meaning to become ill or die.
Use it carefully in a medical context or when commiserating with someone feeling under the weather.
Example: “I’ll skip the barbie today, I’ve been feeling a bit crook since last night.”
6. Bogan
“Bogan” in Australian Slang playfully describes someone seen as unsophisticated or uncultured. It’s often paired with stereotypes, like mullets, flannel shirts, or loud cars, but can be used lovingly among friends.
Depending on tone and company, calling someone a bogan might be friendly ribbing or a mild insult. Always gauge the vibe before you pull out this term.
Example: “He rocked up in his old Commodore wearing thongs and a singlet, total bogan style.”
7. Mozzie
Shortening “mosquito” to “mozzie” is part of Australia’s fondness for abbreviations. Given the country’s warm climate and wetlands, mozzies are a fact of life, especially in summer or tropical regions. You’ll hear warnings to wear repellent, nets, or long sleeves to keep these tiny vampires at bay.
Example: “Don’t forget the mozzie spray when we camp near the creek.”
8. Servo
Need fuel for your car or vending snacks at any hour? Head to the “servo,” Aussie shorthand for service station or gas station.
This abbreviation reflects a broader pattern in Australian English: chopping syllables to make speech quicker and more casual. Servos often double as mini-marts, so Aussies might pop in for lollies, cold drinks, or a sausage roll at any time.
Example: “I’m almost flat-out, gonna pull into the servo for a quick top-up.”
9. Thongs
In Australia, “thongs” aren’t lingerie, they’re flip-flop sandals. Ideal for beaches, backyards, or quick errands, thongs slip on easily and air out sweaty feet.
The term dates back to early 20th-century usage and refers to the thong-like strap that sits between your toes. Try this word in the wrong context elsewhere, and you might get a few raised eyebrows!
Example: “Pack your togs and thongs, we’re off to Bondi Beach.”
10. Tradie
Tradespeople, electricians, plumbers, builders, are crucial to keeping Australia running. “Tradie” is the affectionate shorthand for “tradesman” (or tradesperson).
Calling someone a tradie in Aussie Slang respects their skillset and hard work. Whether you’re arranging a house repair or praising a welding job, this term signals you understand local work culture.
Example: “We need a tradie to sort out the dodgy wiring in the kitchen.”
11. Barra
Barramundi, affectionately called “barra,” is both a prized game fish and a popular menu item in Australia’s north. Aboriginal languages of the region gave us “barra,” while commercial fishing and tourism spread the word nationwide.
Even if you catch it yourself or order it grilled at a restaurant, “barra” represents fresh, local seafood at its best.
Example: “The local pub’s serving barra tacos tonight, can’t miss that.”
12. Footy
“Footy” covers several codes of football in Australia, most notably AFL (Australian Rules Football) and rugby league or union, depending on your state.
Each season, footy matches dominate weekend broadcasts and local bar chatter. Use “footy” to talk about games, favourite teams, or stadium outings, and you’ll tap into Australia’s rich sporting culture.
Example: “I’ve got tickets to Saturday’s footy match at the MCG.”
13. Bottle-o
To pick up beer, wine, or spirits, Aussies visit the “bottle-o,” short for “bottle shop.” Often attached to pubs or standalone, bottle-os are open late, making them essential for weekend gatherings and last-minute party prep.
Use the term to ask directions, plan a barbecue, or signal you’re the designated drink runner.
Example: “Swing by the bottle-o, grab a six and some ice.”
14. Dag
“Dag” originally referred to wool tangled on a sheep’s rear end, but by the mid-20th century, it morphed into a term for someone a bit unfashionable or socially awkward.
However, calling someone a dag can be affectionate, a nod to their quirky charm. Use it among friends to celebrate eccentricity rather than to wound feelings.
Example: “Sure, he’s a dag with those socks and sandals, but he’s got a heart of gold.”
15. Chockers
In Australian slang words, when something is “chockers,” it’s absolutely packed, be it trains in Sydney rush hour, countertops at a bakery, or your schedule on a busy day.
It likely springs from “chock-full,” meaning stuffed to capacity. Aussies deploy it to convey busyness or overcrowding with punchy economy.
Example: “The park was chockers with families enjoying the sunshine.”
16. Codswallop
“Codswallop” is perfect for calling out nonsense. Whether someone tells a tall tale or you hear an absurd conspiracy theory, “codswallop” dismisses it with irreverent flair.
The word dates back to early 20th-century British usage but found a home in Australia’s love for robust, colorful language.
Example: “All that talk of aliens controlling the weather is just codswallop.”
17. Dunny
In rural Australia especially, the “dunny” refers to a simple toilet or outhouse, often a small shed separate from the main house. Urban usage sometimes applies it to portable toilets at festivals or construction sites.
The term possibly comes from the English dialect “dunnekin,” meaning a small, dirty place.
Example: “Hold your horses, I’ve gotta find the dunny before we hit the road.”
18. Esky
Every Aussie gathering, barbecue, picnic, fishing trip, relies on an “esky,” the ubiquitous portable cooler. Originally a brand name from the 1950s, “Esky” became a generic term for any insulated container keeping drinks and food cold.
If you show up without an esky, you’re practically asking for warm beer.
Example: “Load the beers and snags into the esky; we’re off to the river.”
Cultural Significance & Tips
- Abbreviations & diminutives: Aussies love chopping words—barbecue to “barbie,” afternoon to “arvo,” communication to “commo.” Embrace the habit to blend in.
- Context matters: Tone and company determine whether terms like “bogan” or “dag” stay friendly or risk offense. Always gauge first.
- Regional variations: In Queensland, “footy” usually means rugby league. In Victoria, it means Aussie Rules. In WA, a “servo” might stock local craft beers unheard of elsewhere.
- Media influence: Shows like Neighbours or Kath & Kim helped export dialect around the globe. Listening to Australian podcasts or TV can sharpen your ear for natural rhythms.

With these 18 slang terms, you’ve unlocked the door to authentic Aussie speech. From the laid-back “G’day” to the hearty dismissal of “codswallop,” each word carries a slice of Australia’s history and culture.
