Aussie Homes has partnered with House Hunters to help you find, buy and own your next home.
With cost-of-living pressures biting, more Aussies are rolling up their sleeves and tackling home improvement projects themselves. A few how-to videos and a trip to Bunnings? Feels like you're halfway there. But the DIY trend may be backfiring, with new research showing it’s leading to costly mistakes.
A national survey conducted by hipages, the country’s largest tradie platform, revealed that in the past year alone, around 4.2 million households have experienced a DIY mishap.
Driven by a desire to sidestep tradie fees and speed up renovations, nearly 7 in 10 respondents (69%) said they’d taken on some form of DIY job - most commonly painting (43%), landscaping or garden work (33%), and cabinetry (21%).
What’s causing concern among professionals, however, is the number of homeowners dabbling in more technical tasks usually reserved for licensed tradespeople. Plumbing projects were attempted by 26% of those surveyed, and 18% had a go at bathroom or kitchen tiling, jobs that can lead to big repair bills if done poorly.
The wrong tool or one wrong move can turn a quick fix into a costly mistake and, in some cases, a safety risk or even an insurance headache. So, how do you know when to roll up your sleeves and when to call in the pros? Let's break it down.
Aussies love a good project, and DIY is booming.
Whether it's putting together a cubby for the kids or giving the garden a glow-up, DIY has long been part of Aussie weekend culture. And lately? It's had a serious glow-up of its own.
Australia now ranks third in the world for DIY home renovations. In 2022 alone, 57% of Aussies spent over $12.3 billion on home projects, which is a lot of trips to Bunnings. So, what's behind the surge?
Cost-of-living crunch. With rising expenses, more people are choosing to DIY where they can. Skipping the tradie and tackling that paint job yourself could mean a few hundred saved; when every dollar counts, those wins add up.
Social feeds are full of inspo. Open Instagram or TikTok, and you'll find plenty of clever storage hacks, before-and-afters, and budget renos that look too easy not to try. It's never been simpler to learn, be inspired, and have a crack yourself.
More time at home. Post-pandemic life has changed how we use (and value) our homes. We've spent more time on them, spotted more flaws, and found more reasons to improve them. DIY became both a fix and a creative outlet.
The feel-good factor. Let's be real: there's a proud satisfaction in stepping back and saying you did that DIY reno. DIY isn't just about saving cash. It's about putting your stamp on your space.
Adding value smartly. Not every improvement needs a big spend to boost property value. From curb appeal upgrades to budget bathroom refreshes, even small DIY jobs can make a real difference, especially if you're looking to refinance or sell.
But with more DIY happening, there's also more risk. Some renos need a licence, some affect insurance, and others can go badly if you're not careful. So, it's worth knowing where the line is and when to call in the pros.
The projects perfect for Aussie DIY enthusiasts
Not all projects need a team of tradies or a truckload of tools. Some of the best renos are the ones you can roll up your sleeves and tackle yourself safely, affordably, and with a fair bit of satisfaction. These jobs hit that perfect DIY balance: low risk, low cost, and high reward.
Applying fresh paint is the first on the list. Painting is a classic for a reason. A few tins of colour, some drop sheets, and some prep work can completely transform a room. Whether it's reviving the lounge, brightening up the spare room or giving that old chest of drawers a new life, painting is budget-friendly and beginner-approved.
Just take your time; good prep and proper drying make all the difference.
Another pick is simple installs (like shelves, rods, or hooks). Adding a curtain rod or floating shelf might sound fiddly, but it's well within reach with a drill and a level. Just be sure to check what's behind your walls before drilling. Hitting the right spot makes the difference to the look and safety.
Assembling flat-pack furniture is also on the list—the Allen key, the mystery screw, the instructions that feel like a puzzle. But once you get into the rhythm, assembling is a handy skill. Set aside some time, follow the steps, and keep your cool. An electric screwdriver doesn't hurt either.
Gardening and landscaping basics are also popular. You don't need to be a landscaper to improve your yard. Weekend wins are pulling weeds, planting some colour, adding mulch, or building a raised garden bed. They boost street appeal and property value while giving you a break from screens and stress.
Small swaps also make a big difference. You'd be surprised by how much impact a new tap, cupboard handle, or light fitting can have. These little upgrades can modernise a room fast and stick to changes that don't require a licence (like electrical rewiring or plumbing work). Think of simple updates that refresh without the risk.
These kinds of projects are great for building confidence and breathing new life into your space. These touches can pay off when you're prepping your home for sale, refinancing, or just wanting to fall in love with your space again.
When to call in the professionals
There's nothing wrong with getting your hands dirty until it risks your safety, home or finances. Some jobs are better left to the experts.
Unsurprisingly, 41% of homeowners surveyed said a DIY disaster was mostly likely to occur in the bathroom, followed closely by the kitchen at 32 per cent, with the average cost of repairs seeing homeowners fork out $500 or more.
It's not about giving up; it's about being smart. Even the most confident DIY enthusiasts know when to step back and bring in the right tradie. Here are the jobs where a licensed professional isn't just recommended; it's non-negotiable.
Let's keep this simple: in Australia, doing electrical work is illegal unless licensed. That includes rewiring, installing power points or light switches, or anything beyond changing a bulb. Get it wrong, and you're not just risking a blown fuse.
We're talking about fire hazards, voided insurance, and serious safety concerns. If a job involves wires in the wall, it's time to put the tools down and call an electrician.
Fixing a leaky tap or clearing a blocked drain? That's usually fair game. But if you're touching pipes, installing new fittings or doing anything beyond surface-level maintenance, leave it to a licensed plumber. Water damage has a sneaky way of building up behind the scenes. What starts as a small drip can become expensive, especially when mould or rot sets in.
Thinking about creating an open-plan living area? That wall you want to knock down might be holding up half your house. Any load-bearing modifications need proper structural advice, often a council permit, and a qualified builder. Do it wrong, and you're not just risking safety. You could be reducing your home's value or creating issues when it's time to sell or refinance.
Pro tip: If you plan to use your equity to fund a reno, your Aussie Broker can help you envision what's possible before taking the first swing of the sledgehammer.
It only takes one misstep for roof work to also turn dangerous. Between slippery tiles, uneven surfaces and sheer height, roofing is one of Australia's most common causes of DIY injuries. But it's not just about safety. Your roof protects your home from the elements. Get it wrong, and water can find its way in. A qualified roofer knows how to get the job done properly and safely.
Tiling a small splashback? Go for it. But when it comes to bathrooms, laundries, or any wet zone, waterproofing needs to be spot-on, and in most states, it must be done by a licensed professional. A bad job can cause leaks, hidden damage, and stress later.
Plus, dodgy waterproofing can void your insurance. It is better to let the pros handle the base layer and then step in for the fun stuff like painting and styling.
The real risks of pushing DIY too far
There's nothing wrong with getting stuck into a weekend project until confidence becomes a costly mistake. The truth is, there's a fine line between hands-on and hazardous. And when it comes to home renos, knowing your limits can save you time, money and a lot of stress.
According to recent research, nearly half of Australians have had a DIY job go wrong. The most common blow-ups? Painting reached 43%; gardening reached 33%; plumbing reached 26%; carpentry reached 21%. So, what's at stake when DIY gets out of hand? Let's take a look.
DIY has risks, including ladders, power tools, and sharp edges. While it might start with a quick job, things don't take long to go sideways. Sprains, falls, and even electric shocks are more common than you'd think. If you're taking on a job that involves heavy lifting, heights or anything sharp or sparky, it's worth pausing to ask if you know what you're doing.
A trip to Bunnings is one thing. A trip to the hospital is another.
Many people also forget that if you damage your home by doing unlicensed or unsafe work, your insurance might not cover it. It could even void your policy entirely, especially if the issue is linked to plumbing, electrical work, or waterproofing that doesn't meet Australian Standards.
Botch a reno, and you could void your home insurance, meaning you might be left footing a repair bill of up to $6,600 for work that's not covered because a qualified pro didn't do it.
Even if it looks fine to you, a professional assessor will know. If you plan to sell or refinance, that's the red flag you don't want popping up.
Crooked shelves, uneven tiling, and that one patch of paint that's not quite the same colour will capture the eyes of buyers and valuers. DIY that looks rushed or rough around the edges can affect your home's appeal. If it hides a bigger issue (like water damage or poor ventilation), it can knock tens of thousands off your property's value.
In many states, doing certain work yourself (like electrical, gas, or structural jobs) is illegal, even if it's on your property. Skipping the permits or going beyond what's allowed could result in serious fines, forced removal of the work, or legal liability down the line.
Bottom line? It's not worth the risk. Check what requires a licence or council approval before you break ground, and when in doubt, call a professional.
Our Aussie Brokers are not here to scare you off DIY altogether. There are plenty of safe, satisfying jobs that are perfect for a weekend project (and we've listed some here). But when safety, insurance, or resale value is on the line, it's better to be cautious than sorry.
If you need a second opinion, your local Aussie Broker can help you figure out:
Whether a renovation will add value to your home.
If you can tap into your equity to fund a professional.
What lenders or insurers need to know before you make changes.
We're here to help you avoid the common pitfalls and make confident, well-informed decisions.
The real cost of DIY vs professional renovation
Let's talk about money. While DIY might seem cheaper upfront, it doesn't always stay that way.
That $150 paint job? It can balloon to $700 once you add in brushes, drop sheets, redos, and the weekend you lost doing it. So, before you roll up your sleeves, it's worth looking at how DIY stacks up against the pros, not just in dollars but also in time, stress, and risk.
Sure, DIY seems cheaper. There are no labour costs or call-out fees—just your time and the materials. But those savings can vanish if the job takes longer than expected, doesn't meet standards, or needs fixing later.
As time passed, we've also seen plenty of DIY success stories and ones that ended with a bigger bill than expected. Here are a few traps to watch out for.
Be mindful of buying tools you'll never use again. That $200 power tool is great for one job, but then it lives in the shed. Also, consider the wasted materials from mistakes—crooked cuts, cracked tiles, and peeling paint. Remember, small errors can lead to high costs.
Hiring a tradie to fix it and paying for the job twice is more common than you think. You'll also have to think about the lost time and missed income. If you're using annual leave or skipping side work, your time has a cost, too. And the big one? Confidence. A bad DIY can shake your trust in tackling the next DIY. Sometimes, it's not just about getting the job done; it's about knowing it's done right.
Hiring a licensed tradie often includes:
Warranties and guarantees: If something breaks, they come back and sort it.
Accountability: Licensed pros have to meet codes and standards.
Insurance: DIY gone wrong may not be covered by your home insurance, but qualified work is usually covered.
So, when should you DIY? Ask yourself: Is it safe? Is it legal? Do I have the tools, time and know-how to do this well? Would a pro add value or save me the headache?
If you're unsure, don't guess. Chat with a professional first. Better yet, talk to your local Aussie Broker. We can help you determine if that renovation is worth the spend and whether tapping into your home equity or refinancing could help you do it properly and with confidence.
How to set yourself up for DIY success
There's nothing quite like the feeling of stepping back and thinking you successfully did a DIY. Whether it's refreshing a tired space, ticking off that long-standing to-do, or adding your flair, a good DIY can be equally rewarding and cost-effective. But getting it right takes more than enthusiasm. It takes planning, prep, and knowing when to call in backup.
Here's how to set yourself up for wins, not worries.
Thinking of tackling your first reno? Start small and build up. Skip the bathroom overhaul and start with something bite-sized: a fresh coat of paint, swapping out cupboard handles, or assembling that flat-pack you've been ignoring.
These quick wins will give you a feel for tools, materials, and how long things actually take without the pressure of getting structural or safety-critical work right on your first go.
Smart tip: Stick to projects that won't affect your home's resale value or insurance coverage. Keep it cosmetic, not structural.
Invest in quality basics. You don't need a trailer full of tools, but a few decent essentials can make the difference between a smooth job and a frustrating one. Think: a reliable drill, sturdy tape measure, spirit level, and solid toolkit. The same goes for materials; don't cut corners. Cheap paint or hardware often leads to more work later.
Spend more now to save yourself the hassle (and extra costs) of redoing it.
Learn from people who know their stuff. We're lucky to live in a golden age of reno inspo—Youtube, Instagram, Bunnings workshops, or wherever you like to learn, there's help available. Just make sure it's local. Look for clear, step-by-step instructions, references to Australian safety or building codes, and comments confirming it works in real life.
If you prefer hands-on learning, in-person hardware store demos or weekend classes are a great way to build confidence.
Know your limits, and don't be afraid to ask. The best DIYers know when to put the tools down and involve a pro. If you're unsure whether it's legal, safe, or likely to pay off in the long run, that's your cue to stop and ask.
The takeaway? Start simple, be prepared, and don't wing it on renos that could cost you more than they're worth. Success comes from knowing your strengths and being smart about your limits. DIY should feel like progress, not pressure; your home should reflect your efforts, not your regrets.
DIY and renovation FAQs: What every Aussie should know
Having a few questions is normal wherever you are on your DIY journey. We've pulled together the questions Aussie Brokers get asked most often, along with the answers that'll help you make confident, well-informed choices for your home.
What home reno jobs are off-limits for DIY?
Some jobs are best left to the pros; in many cases, the law says they have to be. Here's what you can't legally DIY in Australia (even if you're handy):
Electrical work, including installing lights, adding powerpoints or rewiring
Plumbing work like moving pipes or installing drainage
Gas fitting, including appliance installation
Structural changes or anything involving load-bearing walls or framing
Waterproofing in bathrooms or other wet areas unless you're licensed
Skip the red tape, and it can cost you. We're talking fines, failed insurance claims, and potential safety risks. Your best move? Check with your state's building authority before you buy the tools.
How do I find a qualified tradie I can trust?
It's not about luck; it's about knowing where to look. State licensing websites like Fair Trading NSW, VBA VIC, or QBCC QLD are perfect for checking qualifications. You can also try industry bodies and look for registered members of the HIA or Master Builders Australia, which is a good sign.
Ask your neighbours, mates, or local Aussie Broker. We know who's good in your area. You can also read online reviews and cross-check platforms like Google and ProductReview to spot red flags.
Pro tip: A legitimate tradie will always be happy to show you their licence and insurance and provide a written quote with timelines. If they don't, walk away.
Can DIY affect my home insurance?
It sure can, and not in a good way. Your insurance provider might not cover the damage if something goes wrong because of unlicensed or unsafe DIY work.
In some cases, it could void your policy completely. Even small jobs, like shelves or tap fittings, can trigger problems down the track if they're not done properly. To stay covered:
Read your policy before you start.
Tell your insurer about any major changes, even if you DIYed them.
Use licensed tradies for anything involving plumbing, wiring or structure.
DIY can save you money, but only if it doesn't cost you a claim.
What should I check before hiring a tradie?
Before signing on, ensure your contractor checks all the right boxes. Some must-haves include a valid trade licence for your state or territory, public liability insurance, WorkCover insurance (if they have staff), an ABN, and a written contract with clear scope and pricing.
Depending on the job, you should also ask for waterproofing accreditation, asbestos handling certificates (for older homes), and proof that they meet Australian Standards and the National Construction Code.
Before you go all-in on your next project, talk to your local Aussie Broker. We'll help you make smart, confident decisions and avoid DIY dramas.
DIY with confidence, not guesswork.
DIY can be one of the most rewarding parts of owning a home, but only when done right. It allows you to add your style, save some money, and get stuck into something with your own two hands. However, not every job should be a solo mission.
The smartest renovators know where their skills end, and the pros step in. Whether it's a legal issue, a safety risk, or a reno that could impact your insurance or resale value, knowing when to call in help can save you big in the long run.
If you're planning a renovation, unsure what's allowed, or wondering how to fund it smartly, your local Aussie Broker is a great place to start. We'll help you explore your options, tap into your home equity if it makes sense, and avoid the common mistakes that catch people out.
Getting the job done right isn't just about tools and tiles; it's about having the right plan.
