Carsales.com: the classifieds site that quietly went global

Ask most Australians what carsales.com does and you'll get a shrug and "sells cars, I guess." Ask an equity analyst covering the ASX and you'll get something closer to reverence. That gap between public perception and financial reality is basically the whole story of this company, and it's why I keep coming back to it whenever someone asks me for an example of an Australian internet business that actually built something durable rather than just riding a boom.

I've spent a fair bit of time this year going back through carsales' annual reports for a longer project on Australian marketplace businesses, and the thing that stands out isn't the domestic dominance — that part is well understood. It's how methodically the company has exported the same playbook into Asia, Latin America and, more recently, the United States, while barely making a noise about it at home.

From classified ads to online monopoly

Carsales began life in the 1990s as a print classifieds operation before making the jump online, at a time when most Australian media companies still treated the internet as a curiosity rather than a threat. That early move mattered enormously. By the time newspapers worked out that their classified sections were the most profitable and most vulnerable part of their business, carsales already had the audience, the dealer relationships and the data.

The company listed on the ASX in 2009, and from there the domestic story is fairly linear: it became the default place Australians go to buy and sell a car, squeezed out or absorbed smaller rivals, and built a two-sided network effect that's genuinely hard to dislodge. Dealers need to be where the buyers are, buyers go where the inventory is, and once that flywheel is spinning it's very difficult for a challenger to get enough of either side to make a dent. It's the same structural logic that turned REA Group into a property listings monopoly and SEEK into the default jobs marketplace — Australia seems to be unusually good at producing these category-killer classifieds businesses, possibly because the market is small enough that winner-take-most dynamics play out fast.

Why the international push actually worked

Plenty of Australian companies have tried to take a domestic template overseas and failed because they assumed the same playbook would just work in a different market. Carsales' international expansion has been more disciplined than that, and I think it's the most underrated part of the business.

Rather than trying to build greenfield operations from scratch in unfamiliar markets, the company has largely bought its way into leadership positions — taking meaningful stakes in existing local platforms in South Korea, Brazil, Mexico, Chile and Indonesia, then layering in its own product and monetisation expertise rather than its brand. That's a subtle but important distinction. Most of these platforms don't carry the carsales name at all; they trade under their own local identities, which means the company gets the economics of category leadership without having to win a branding war in a market it barely understands.

It's a strategy that echoes what Macquarie has done in infrastructure — buy operating expertise into a position of scale rather than trying to out-market incumbents from a standing start. I'd argue it's a more honest form of expansion than the "we'll just export our app and see what happens" approach that's sunk more than a few ASX-listed ambitions offshore.

The US bet: Trader Interactive

The clearest signal of how seriously carsales takes international growth is its move into the United States through Trader Interactive, a business covering commercial trucks, recreational vehicles and equipment marketplaces rather than passenger cars. Carsales built its position there in stages, moving from a minority stake to full ownership over a period of years — a patient, capital-intensive approach that isn't typical of Australian companies trying to crack the US market. It's a genuinely large piece of the current business now, and it's the segment I watch most closely in the half-year results, because it tells you whether the international thesis is holding up or whether the US market is proving tougher to crack than the Latin American and Asian bets.

What the numbers actually show

Here's where I want to be careful, because it's easy to get swept up in the "Australian company conquers the world" narrative without checking whether the underlying economics support it. Carsales doesn't disclose every regional segment with the same granularity, and currency movements can flatter or punish the international numbers in ways that have nothing to do with underlying performance. When the Australian dollar weakens against the Brazilian real or the US dollar, reported international revenue can look stronger than the operational reality, and vice versa.

What I can say with confidence, from reading successive annual reports rather than taking the investor-day slide decks at face value, is that international revenue now makes up a substantial and growing share of group earnings, and that the domestic Australian business — while still the profit engine — is no longer the whole story the way it was a decade ago. That's a meaningfully different company to the one that listed in 2009, and it's why I think the market sometimes still prices carsales like a domestic classifieds business when it's increasingly a portfolio of marketplace stakes across several continents.

The competitive risk nobody talks about enough

The domestic business faces a slow-burning risk that gets less attention than it should: car manufacturers and dealer groups building their own direct-to-consumer sales channels, cutting out third-party marketplaces altogether. It hasn't materially dented carsales' position yet, and dealer network effects are genuinely sticky, but I'd want to see that risk taken more seriously in investor commentary than it currently is. Every dominant marketplace eventually faces disintermediation attempts from the supply side — REA has faced versions of this from agents, SEEK from direct-hire platforms — and the ones that survive are the ones that keep making themselves indispensable rather than just defensible.

Why this matters more than the headlines suggest

I moved to Perth a few years back after covering east-coast tech for most of my career, and one thing that strikes me out here is how little attention companies like carsales get relative to the mining and energy names that dominate local business coverage. That's understandable given where the state's economy sits, but it means genuinely global Australian success stories — carsales, SEEK, even Afterpay before its sale — don't get the scrutiny or the credit they deserve until something dramatic happens, good or bad.

Carsales isn't a flashy story. There's no founder mythology being sold on a stage, no billion-dollar acquisition headline every other month. It's a company that worked out a formula in Melbourne, proved it repeatedly at home, and then spent the better part of two decades quietly buying its way into similar positions overseas. That's not a game-changer of a narrative. It's just a very well-run marketplace business that happens to operate on four continents, and in my experience those are exactly the companies worth watching most closely.
