Interview Questions for Labourers

The concrete truck is booked, the gate is open and your new labourer is missing. You ring. No answer. Now someone else has to carry the load.

A labourer can look like an easy hire until they miss a start or ignore a safety rule. These interview questions for labourers help you test the basics before you offer. No set of questions can promise a good hire.

This guide is for builders, subbies and contractors hiring labourers. If you're a labourer getting ready for an interview, there are plenty of "how to answer" guides out there. This one is for the person doing the hiring.

The short answer: what should I ask a labourer in an interview?

Ask about turning up, safety and the work they've really done. Ask how they get to site and what time they can start. Ask what they'd do if told to do something unsafe. Check their White Card. Ask everyone the same questions, take notes, and call a foreman they worked for before you offer.

A labourer who doesn't last costs more than you think. Work out what a wrong hire could cost you with your own numbers. Our post on the cost of a bad hire in construction breaks it down.

Before the interview: know what "labourer" means on your site

"Labourer" covers a lot. Cleaning up and loading out is one job. Barrowing concrete, setting out or running a compactor is another.

Before you talk to anyone, write down three things:

• The work. What will they actually do in week one?
• The must-haves. A White Card, plus any licence the tasks really need. Ask for a reliable travel plan, not car ownership unless the job needs it.
• The hours. Start time, finish time, Saturdays, and how long the job runs.

That list is also the start of your job ad. Our tradie job ad template shows how to turn it into an ad people reply to.

Turning up: the questions that matter most

For a labourer, turning up is half the job. So start here.

1. "How will you get to site each day?" Listen for a reliable plan and a backup. A lift or public transport can work if it gets them there on time.
2. "Our start is 6:30. What time would you leave home?" A good answer has a real time in it. It shows they've thought about the trip.
3. "Tell me about your last job. How did it end?" Listen for a clear story. "The job finished" is fine. Vague answers are worth a follow-up question.
4. "What would you do if you were running late?" You want "I'd ring the foreman before start time." Not "I'd just get there."
5. "Can you do Saturdays if we need them?" Ask for an honest answer now, not after you've hired them.

Ask about the job, not about their home life. If the role needs early starts or travel, ask if they can do that. Don't ask about kids or family to find out. The Australian Human Rights Commission's guide to preventing discrimination in recruitment gives the same advice.

Safety questions for a construction labourer

A new labourer who doesn't speak up can get hurt, or get someone else hurt. These questions show how they think.

6. "Do you have a White Card? Can I see it?" Safe Work Australia says workers must have a construction induction (White Card) card before they can start on a construction site. They must show it to the business running the site when asked.
7. "What would you do if the foreman asked you to do something you thought was unsafe?" You want to hear "stop and ask." Going along with it to keep the peace is a warning sign.
8. "Have you worked near moving plant or in trenches?" Listen for real examples and what they did to stay safe.
9. "Have you read and signed a SWMS before?" A SWMS is a safe work method statement. It sets out the hazards and controls for high risk construction work. Safe Work Australia lists the high risk construction work that needs a SWMS, like work with a risk of falling more than 2 metres. A green labourer may not know the word. That's fine. You're checking if they'll read it.
10. "Tell me about a time something went wrong on site. What did you do?" Good answers are specific and honest.

One thing not to ask: "Have you ever made a workers' compensation claim?" The Human Rights Commission says it may be against the law to ask that, or how much sick leave someone took. Ask instead if they can do the genuine tasks of the job, like lifting and carrying.

General information only, not legal advice. Check the Australian Human Rights Commission guide and your state WHS regulator for your situation.

Questions about the work itself

Now find out what they can really do.

11. "Walk me through a normal day on your last site." You want tasks, tools and the type of job. "Just labouring" needs a follow-up: "Like what?"
12. "What tools and machines can you use on day one?" Ask for honesty. Someone who says "never used a plate compactor, happy to learn" is more useful than someone who bluffs.
13. "Which trades have you worked alongside?" Labourers who've helped concreters, formworkers or bricklayers know how a site runs.
14. "What's the hardest physical day you've done?" You want a real story. It tells you if they know what the job feels like.
15. "What do you do when you've finished a task and the foreman's busy?" Look for "clean up safely and ask what's next." They should not start a new task without the training or go-ahead it needs.

If you want a labourer who could become an apprentice later, ask: "Is there a trade you'd like to learn?" It tells you who wants to stay and grow. We cover that path in how to hire an apprentice in Australia.

A short trial: do it the right way

Want to see how they work? Plan a paid, supervised skills check. Agree the tasks, hours and pay before they start. Check the pay rate and employment terms with your workplace adviser.

Don't assume an hour is free just because you call it a trial. Time alone does not settle whether work can be unpaid. We could not open the full Fair Work unpaid trials page during this review, so this guide does not advise you to use an unpaid trial.

Paying does not remove your safety duties. Check the White Card, give an induction and put a supervisor beside them. Choose a task that suits their skills. Don't use a trial as a way to leave a new person alone on risky work.

General information only, not legal advice. Check Fair Work's unpaid trials page for your situation.

Red flags to listen for

Watch for these in the interview:

• They can't name a single site or task from their last job.
• Every past boss was "a joke" and every job ended badly.
• They have no plan for getting to site.
• They'd do unsafe work to avoid trouble.
• They say yes to everything, even things that don't fit what they told you earlier.
• They can't show a White Card and have no plan to get one.

One red flag isn't always a deal breaker. Ask a follow-up question. Two or three together usually are.

Score it, check it, decide fast

Use the same questions for every labourer. Then score each answer quickly. A simple 1 to 3 works:

Score	What it means
1	Weak or vague answer, or a red flag
2	OK answer, nothing special
3	Clear, real example, and it fits your site

Add up the scores. Then call a foreman or site manager they worked for. Ask what they were like on their worst day. Our post on reference check questions for tradies has the full list.

Once the checks are done, give them a clear answer. Tell them when you will call, then keep that promise.

Once they start, give them a clear plan for the first fortnight. Our guide on how to keep good tradies covers what to do.

Quick checklist before the offer

• They have a clear plan to get to site on time.
• Their White Card is sighted.
• Their answers on safety were "stop and ask," not "just do it."
• You asked every candidate the same questions.
• You've called at least one foreman or site manager who supervised them.
• Any work trial has agreed pay, safe tasks and proper supervision.

FAQ

What interview questions should I ask a labourer?

Ask how they get to site, what time they can start, and what they did on their last job. Ask what they'd do if told to do something unsafe, and check their White Card. Ask every candidate the same questions, score the answers, then call a foreman who supervised them before you make an offer.

What should a construction labourer know before starting on site?

They need a White Card before they start on a construction site, says Safe Work Australia. They should know how to follow a foreman's directions, wear the right PPE and speak up about unsafe work. If they'll do high risk work, they should read and follow the SWMS for it before they start.

Can I do an unpaid trial for a labourer?

Do not assume a short trial can be unpaid. This guide recommends a paid, supervised skills check with tasks and pay agreed first. We could not open Fair Work's full unpaid trials page during this review. Check the official guidance or get workplace advice before relying on an unpaid arrangement.

What are red flags when interviewing a labourer?

Watch for no plan to get to site, no real examples from past jobs, and blaming every past boss. Another big one is saying they'd do unsafe work to avoid trouble. One red flag needs a follow-up question. Two or three together usually mean you should keep looking.

What should I not ask in a labourer interview?

Stick to the job. Don't ask about family, kids, religion or where someone is from. The Australian Human Rights Commission says it may be against the law to ask about past workers' compensation claims or sick leave. Instead, ask if they can do the genuine tasks of the role. This is general information, not legal advice.
