Subaru Outback Best Years Australia: Which Models Are Worth Buying?

Finding the Subaru Outback best years in Australia sounds simple until we actually start shopping. There are petrol models, diesels, naturally aspirated engines, turbocharged XT versions, different generations, technology updates, and enough trim names to make a used-car listing feel like alphabet soup.

The good news? The Outback has been one of Subaru’s most useful Australian models for years. It sits somewhere between a traditional wagon and an SUV, combining a relatively low, comfortable driving position with generous ground clearance, permanent all-wheel-drive capability, a roomy cabin, and enough practicality for everything from Melbourne commuting to a muddy camping weekend in the Victorian High Country.

But some model years make considerably more sense than others.

For most Australian used-car shoppers, 2018–2020 Outbacks represent the sweet spot for value, while 2021–2022 models are among the strongest choices for buyers wanting a newer, safer and more refined vehicle. Buyers wanting considerably more performance should put the 2023–2025 Outback XT high on the shortlist.

Let’s break down which Subaru Outback years deserve our money—and which ones deserve a much closer inspection.

What Are the Best Subaru Outback Years in Australia?

If we wanted the short answer before digging into the details, our Australian shortlist would look like this:

That ranking isn't a claim that every 2019 Outback will automatically outlast every 2017 or 2021 example. Used vehicles don't behave that neatly.

A meticulously serviced older Outback can easily be a better purchase than a newer one that has missed maintenance intervals, been repeatedly driven on unsuitable tyres, or spent its life towing heavy loads.

That matters particularly with Subaru vehicles. Australian used-car guidance from CarsGuide similarly stresses the importance of complete servicing when evaluating an Outback and characterises overall reliability as more dependent on vehicle history than Subaru's reputation alone might suggest.

Why the 2018–2020 Subaru Outback Is Our Used-Car Sweet Spot

For many Australians, this is where the numbers begin making sense.

The fifth-generation Outback arrived earlier, but by 2018 Subaru had already had several years to develop and refine the platform. Buyers also gained a strong blend of modern safety equipment, comfortable touring ability, smartphone connectivity on relevant versions, and a cabin that still feels perfectly usable today.

A current Australian used-market search shows 2018 examples continuing to appear in meaningful numbers, including 2.5i, 2.5i Premium, 3.6R and diesel variants.

That availability matters. More cars for sale generally gives us more freedom to reject questionable examples instead of falling in love with the first Outback wearing shiny paint and freshly applied tyre dressing.

2018 Subaru Outback: One of the Strongest Bargains

The 2018 Subaru Outback is particularly interesting.

This was a mature version of the fifth-generation vehicle, and Australian buyers could choose between several engines and trim levels. The 2.5i Premium is especially attractive because it balances operating costs, equipment and resale appeal.

Australian specifications for the 2018 2.5i Premium include a continuously variable transmission, five-star safety credentials for its period and a claimed combined fuel figure around 7.3L/100km.

It isn't fast. Nobody will confuse a naturally aspirated 2.5-litre Outback with a WRX after pressing the accelerator.

But speed isn't really the point.

For family duties, road trips, wet highways and gravel access roads, the 2.5i is the sensible pair of hiking boots in the cupboard. It just gets on with the job.

Why We Like the 2019 Subaru Outback

The 2019 Outback follows essentially the same formula, which is precisely why we like it.

By this stage the fifth-generation design was well established. We aren't buying a first-year redesign filled with unknown variables. Instead, we're looking at a vehicle late in its generation, when manufacturers have generally had plenty of time to iron out smaller production and software wrinkles.

A well-kept 2019 2.5i Premium with sensible kilometres and documented servicing is one of the first Outbacks we'd search for on the Australian second-hand market.

The Real Advantage Is Depreciation

Someone else has already absorbed a substantial chunk of the vehicle's depreciation.

That's the sweet sound used-car buyers like to hear.

The car may still provide adaptive safety technology, a roomy boot, good ground clearance, permanent AWD and modern smartphone integration, yet it costs considerably less than a nearly new Outback.

That's why a clean late-fifth-generation car can make more financial sense than stretching the budget simply to put a newer registration year in the driveway.

2020 Subaru Outback: The Last of Its Generation

The 2020 model deserves special attention because it effectively represents the mature end of the fifth-generation Australian Outback era before the sixth-generation vehicle launched locally in 2021.

We generally like late-generation cars because their engineering has been in production for years. They may lack the newest styling and enormous touchscreen, but they tend to offer something more valuable to cautious second-hand buyers: familiarity.

Mechanics know them. Parts availability is established. Common wear points are better understood. Used examples have accumulated enough kilometres for real-world patterns to emerge.

A 2020 Outback with an excellent history can therefore be one of the smartest purchases in the entire range.

Is the Subaru Outback 3.6R Worth Buying in Australia?

Now we get to one of the interesting ones.

The 3.6R is the Outback we'd buy with the heart rather than the spreadsheet.

Instead of the familiar 2.5-litre four-cylinder, it uses Subaru's larger six-cylinder boxer engine. Contemporary Australian reviews positioned the 3.6R as the premium, more powerful member of the range, with equipment including a Harman Kardon audio system and three-mode SI-Drive.

Its biggest advantage is effortless performance.

Where the 2.5-litre car sometimes needs a deep breath before overtaking on a country highway, the 3.6R feels considerably more relaxed.

Load the boot. Add passengers. Turn on the air conditioning. Point it towards the Blue Mountains.

The engine doesn't seem particularly concerned.

2018–2020 3.6R Models Are Future Used-Car Favourites

We wouldn't be surprised if good 3.6R examples become increasingly sought after.

Large naturally aspirated six-cylinder engines are disappearing, and the 3.6R represents a distinctive chapter in Outback history.

There is a catch, naturally: fuel.

The six-cylinder is thirstier than the 2.5-litre model. Australian specification information lists combined consumption for the 2018 3.6R at roughly 9.9L/100km.

Real-world consumption will depend on traffic, load, driving style and conditions.

For someone doing short urban journeys every day, we'd favour the 2.5.

For someone regularly travelling long distances and wanting effortless power, we'd happily investigate the 3.6R.

Why 2021–2022 Are Among the Best Modern Subaru Outback Years

The sixth-generation Outback reached Australia in March 2021, representing a substantial step forward in technology, refinement and safety. Subaru itself described the new generation as adding technology and crossover capability when it launched locally.

This is where the Outback started feeling less like an ageing wagon cleverly disguised as an SUV and more like a genuinely modern family crossover.

Cabin quality improved. Ride comfort remained excellent. Driver-assistance systems became more sophisticated. The interior grew more contemporary.

And underneath it all, the Outback retained its fundamental personality.

Why the 2021 Subaru Outback Is So Appealing

A good 2021 Outback is arguably one of the best all-round used examples Australians can buy.

It is modern enough to feel current but old enough that depreciation has started doing useful work for second-hand buyers.

The safety story is particularly strong.

ANCAP awarded the Australian-market sixth-generation Outback a five-star rating under its 2021 protocols. ANCAP reported particularly high scores in child occupant protection and safety-assistance testing.

For families, that is a meaningful advantage.

Should We Worry That 2021 Was the First Year?

First-year models often make used-car buyers nervous, and that caution isn't unreasonable.

Whenever a manufacturer introduces a substantially redesigned vehicle, new electronics and software can create irritating early-production quirks.

For that reason, we'd inspect a 2021 example carefully and verify that any applicable updates, campaigns or recalls have been addressed.

But we wouldn't automatically avoid the year.

A well-maintained 2021 Outback remains an extremely compelling used family vehicle.

2022 Subaru Outback: Perhaps the Safest Bet

If our budget allows it, 2022 may be an even easier recommendation.

Why?

It preserves essentially everything attractive about the new generation while moving one production year beyond the initial launch.

That makes a 2022 2.5-litre Outback one of our favourite choices for buyers who aren't chasing outright performance.

It feels modern, spacious and secure without carrying the price of the latest vehicle.

In many ways, 2022 is the Goldilocks Outback: not too old, not too expensive, not unnecessarily complicated.

2023 Subaru Outback XT: The Year Performance Returned

Then Subaru added spice.

Australian buyers received the 2.4-litre turbocharged Outback XT in 2023, bringing substantially more performance than the naturally aspirated 2.5-litre version. Contemporary Australian reporting lists the XT at 183kW and 350Nm.

That's a noticeable jump.

The XT doesn't turn the Outback into a sports car, but it completely changes how relaxed the vehicle feels under load.

Accelerating onto a freeway becomes easier. Overtaking requires less planning. Mountain roads become less laborious.

And towing becomes much more interesting.

The XT Is Our Pick for Australian Touring

If our typical holiday involves a loaded vehicle, luggage, bikes, camping equipment or a trailer, the XT makes a convincing argument.

Australian-specification information for recent XT variants quotes braked towing capacity up to 2400kg, and Subaru explains that XT models receive additional mechanical provisions associated with their greater towing capability.

That does not mean we'd automatically hitch a 2400kg caravan to one and disappear across the Nullarbor.

Maximum towing capacity is only one part of a towing setup. Payload, tow-ball load, gross vehicle mass, axle limits and real-world stability all matter.

But compared with the standard 2.5, the XT clearly gives touring buyers more breathing room.

Are 2024 and 2025 Subaru Outbacks Good Years?

Yes.

In fact, 2024 and 2025 models are arguably among the most polished versions of the sixth-generation Outback.

By then the platform was established, turbocharged XT choices were available, and buyers could select between efficiency-oriented naturally aspirated versions and stronger turbo variants.

A 2024 Australian Outback Sport review recorded claimed combined consumption of 7.3L/100km for the naturally aspirated version, demonstrating why the 2.5 still makes sense for owners who don't need turbo performance.

Meanwhile, a 2025 Sport XT carries the 2.4-litre turbo engine, 183kW and 350Nm, with a 2400kg braked towing figure.

So which one would we buy?

If we mostly commute and road-trip lightly, the 2.5.

If we regularly tow, travel fully loaded or simply dislike sluggish overtaking, the XT.

What About the All-New 2026 Subaru Outback?

Australian buyers now have another wrinkle to consider.

Subaru Australia lists an all-new 2026 Outback, meaning the model line has entered another chapter.

For a used-car buyer, however, new generations often make the outgoing generation more interesting rather than less.

Why?

Because whenever a new shape arrives, older cars suddenly look older in dealer photographs—and prices eventually reflect that perception.

Mazda CX-5 Maxx vs Touring comparison Australia

The mechanical ability of a 2023 or 2024 Outback doesn't suddenly disappear because a newer one has appeared in the showroom.

For value hunters, that can create opportunity.

We would not yet call 2026 the "best year" for long-term ownership because there simply isn't enough Australian long-term evidence to make that judgement confidently. Newest does not automatically mean proven.

Are 2015–2017 Subaru Outbacks Still Worth Buying?

Absolutely—but condition starts becoming much more important.

The fifth-generation Outback launched locally for 2015 and carried a five-star ANCAP rating under the testing criteria applicable at the time.

These cars can provide enormous value.

A 2015 or 2016 Outback still gives us AWD, generous ground clearance, a roomy interior and comfortable highway manners for far less money than a newer SUV.

The problem is age.

At roughly a decade old, rubber components, suspension bushes, batteries, wheel bearings, cooling-system components and other wear items become more relevant than what the original brochure promised.

Service History Beats Model Year

This rule deserves to be painted above every used-car dealership entrance:

Buy the history, not just the badge.

We'd rather own a 2016 Outback with complete receipts, sensible kilometres and an owner who changed fluids religiously than a neglected 2020 example that has spent its life surviving on warning lights and optimism.

Check How It Has Actually Been Used

An Outback may look like a gentle family wagon yet have lived a surprisingly adventurous life.

Inspect underneath it.

Look for damaged plastic shields, dents, scraping and evidence of repeated gravel or off-road use.

Check the tyres too.

Subaru's AWD system is happiest when tyres are appropriately matched in size and wear. A vehicle running one nearly new tyre alongside three heavily worn ones deserves questions.

Should We Avoid Diesel Subaru Outbacks?

Australian Outbacks were sold with diesel power during earlier generations, and some buyers love them for their low-down torque and long-distance economy.

However, we'd approach an ageing diesel Outback more cautiously than an equivalent petrol model.

Modern diesel engines rely on emissions-control systems that prefer proper operating temperatures and sustained driving.

A vehicle that has spent years crawling through short suburban journeys may not have experienced the kind of running conditions a diesel likes.

That doesn't mean every diesel Outback is bad.

Far from it.

But unless diesel economy is central to our needs, the petrol versions usually make a simpler used-car proposition.

What About Subaru Outback CVT Reliability?

The continuously variable transmission is one of the most common concerns potential Outback buyers raise.

And understandably so—gearbox repairs are not pocket-change events.

We shouldn't assume every CVT is problematic, but we should inspect its behaviour carefully.

During a test drive, acceleration should feel smooth and predictable. We should pay attention to unusual shuddering, hesitation, abnormal whining, warning lights or behaviour that feels inconsistent between cold and fully warmed operation.

Service records matter again.

If something feels wrong, don't let a seller explain it away with, "They all do that."

Get an independent inspection.

A pre-purchase inspection can seem expensive right up until it saves us from buying somebody else's expensive mechanical problem.

Best Subaru Outback Year for Different Australian Buyers

There isn't one universally perfect year because an Outback doing the Brisbane school run has a different job from one pulling a camper through regional Western Australia.

For most shoppers, we'd divide the choices this way:

• Best overall used value: 2018–2020 Subaru Outback 2.5i Premium.
• Best older performance choice: 2018–2020 Outback 3.6R.
• Best modern family model: 2022 Outback 2.5.
• Best newer bargain: 2021 Outback with excellent history.
• Best performance model: 2023–2025 Outback XT.
• Best towing-oriented choice: 2023–2025 XT.
• Best lower-budget option: well-maintained 2015–2017 petrol Outback.
• Best choice for simplicity: naturally aspirated petrol models with documented servicing.

Which Subaru Outback Years Would We Be More Careful With?

We wouldn't create a dramatic blacklist of Outback years because vehicle condition varies enormously.

Instead, we'd apply extra caution to three categories.

First, early examples from any new generation deserve particularly thorough inspections because they were produced before years of real-world feedback accumulated.

Second, high-kilometre diesel models deserve careful mechanical evaluation, especially where previous driving patterns are unknown.

Third, any Outback—regardless of year—with incomplete service history should immediately drop down our shopping list.

A cheap Subaru with uncertain history can become an expensive Subaru remarkably quickly.

What Should We Check Before Buying a Used Subaru Outback?

The exterior is the easy part.

Almost anyone can notice a scratched bumper.

The expensive clues are subtler.

We'd check service records carefully, verify the VIN against applicable recall information, inspect all four tyres, test every electronic function, listen to the suspension on rough roads, test the CVT cold and warm, examine the underside for impact damage, check for fluid leaks and make sure every dashboard warning light illuminates and then goes out normally after startup.

Subaru Outback Reliability Australia: Is It a Dependable SUV?

We would also arrange an independent pre-purchase inspection.

On a $20,000, $30,000 or $40,000 vehicle, spending a little money to understand its condition is insurance against buying a beautifully detailed mistake.

Subaru Outback 2.5 vs 3.6R vs XT: Which Is Best?

The 2.5-litre petrol is the sensible choice.

It's adequate for daily driving, typically easier on fuel than the larger engines and widely available.

The 3.6R is the characterful choice.

Its six-cylinder engine provides smoother, stronger performance, although we'll visit the petrol station more often.

The 2.4-litre XT turbo is the powerful modern choice.

It delivers significantly more torque and makes towing, overtaking and fully loaded touring much easier.

Our wallet likes the 2.5.

Our nostalgic side likes the 3.6R.

Our right foot likes the XT.

Is a Subaru Outback a Good Used Car in Australia?

For the right buyer, yes.

The Outback makes particular sense for Australians who want SUV-like capability without buying a heavy ladder-frame four-wheel drive.

It's well suited to wet roads, gravel routes, ski trips, camping access tracks and long highway journeys. Yet it remains manageable around town.

Its biggest selling point may simply be versatility.

Think of the Outback as the Swiss Army knife of family cars.

There are vehicles that tow more. Vehicles that use less fuel. Vehicles that are faster. Vehicles with seven seats.

But few combine passenger-car comfort, AWD, useful clearance, cargo space and long-distance manners quite the same way.

Are Newer Subaru Outbacks Always Better?

Not necessarily.

A newer car gives us newer safety technology, fresher components and fewer years of wear.

But depreciation matters.

A three- or five-year-old Outback can deliver most of the capability of a newer one for substantially less money.

That's why our favourite years aren't simply the newest available.

The best used vehicle lives at the intersection of age, condition, specification, purchase price and maintenance history.

That's a much smarter target than chasing a particular registration year blindly.

Our Final Ranking of Subaru Outback Best Years in Australia

If we were shopping with our own money, 2018–2020 would be our first hunting ground for value.

Those late fifth-generation models combine useful technology with mature engineering and attractive second-hand pricing.

If the budget stretches further, 2021–2022 models offer the strongest balance of modern safety, refinement and depreciation, with the 2022 Outback perhaps being the easiest all-round recommendation.

For buyers prioritising performance, loaded touring or towing, the 2023–2025 XT stands above earlier four-cylinder versions thanks to its 2.4-litre turbo engine and stronger towing credentials.

And what about older Outbacks?

We wouldn't dismiss them.

A properly cared-for 2015 or 2016 petrol model can still be an excellent car. Once vehicles reach that age, however, service history matters far more than a "best year" ranking ever could.

The badge tells us what the car was when it left the factory.

The service records tell us what it has become.

Conclusion: Which Subaru Outback Year Should You Buy in Australia?

So, what is the best year Subaru Outback to buy in Australia?

For value, we'd choose 2018, 2019 or 2020.

For a newer family car, we'd target 2021 or preferably 2022.

For performance and touring ability, we'd choose a 2023–2025 Outback XT.

The trick is not to obsess over finding one magical production year.

Find the best combination of year, engine, condition, kilometres, maintenance history and price.

A beautifully maintained Outback with complete records will nearly always be the smarter companion than a newer model that has been neglected.

Buy carefully, and an Outback can feel perfectly at home whether we're navigating Sydney traffic, crossing Tasmania in winter or chasing an empty campsite hundreds of kilometres from the nearest office tower.

Frequently Asked Questions

1. What is the best used Subaru Outback year in Australia?

For many buyers, 2018–2020 models offer the best combination of price, equipment and maturity. A 2.5i Premium from this period is particularly attractive for everyday family use. Buyers with a larger budget should also consider 2021–2022 models for their newer safety technology and more refined sixth-generation platform.

2. Is the 2021 Subaru Outback a good year?

Yes. The sixth-generation Outback launched in Australia in March 2021 and received strong safety results from ANCAP. Because it was the first Australian year of a new generation, we'd verify its service history and applicable updates carefully, but a well-maintained example can be an excellent used purchase.

3. Which Subaru Outback engine is best in Australia?

The 2.5-litre naturally aspirated petrol engine is the best fit for most owners because it balances everyday performance and running costs. The older 3.6R suits buyers wanting smooth six-cylinder performance, while the 2.4-litre turbo XT is our choice for stronger acceleration, towing and loaded touring.

4. Is the Subaru Outback XT worth buying?

It can be. The Australian XT uses a 2.4-litre turbocharged boxer engine producing 183kW and 350Nm in 2023–2025 specification, providing noticeably stronger performance than the standard naturally aspirated version. Buyers who regularly tow or travel with a fully loaded vehicle will appreciate the difference most.

5. How many kilometres is too many for a used Subaru Outback?

There is no universal kilometre limit. A high-kilometre Outback with excellent servicing can be a safer purchase than a lower-kilometre vehicle with missing maintenance records. Once we're looking beyond roughly 150,000km, however, we'd pay particularly close attention to transmission behaviour, suspension wear, oil leaks, cooling-system condition, wheel bearings and evidence of previous towing or rough-road use.
