A fair question we get: "where does Serge actually find the tours?"
Short answer: Serge's inventory is powered by Viator's Australia catalog, currently around five thousand listings covering every major region. Underneath that, there's a second layer we built ourselves that decides what you actually see. This post explains both.
Layer one: the inventory
Viator is the largest tours and experiences platform in the world, owned by Tripadvisor. For Australia specifically, almost every reputable tour operator is on it. Reef boats in Cairns, surf schools in Byron, hinterland walks on the Gold Coast, Whitsundays sailing days, Uluru helicopter scenics. When we sync their Australia catalog into Serge we start with a real, vetted inventory of things that are actually bookable today.
This matters for two reasons. First, every suggestion Serge makes carries the operator's current price and next available dates, refreshed automatically. Second, when you decide to book, the link Serge gives you goes to Viator's own checkout on the operator's page. You pay them, not us. (The longer version of why that matters is in our post on why Serge doesn't take your card.)
Viator isn't the whole story, though. A catalog of five thousand options is a warehouse, not a recommendation.
Layer two: what we do on top
A global OTA's job is to rank five thousand options so you can search through them. That's useful if you already know exactly what you want. It's terrible if you're standing in a campervan at 6pm in Noosa, a day older than you were in Byron, and you just want someone to tell you the one reef trip worth the early start.
Which is the work Serge actually does. A few layers:
Curated enrichment. Every experience in the catalog is run through a lightweight AI pass that tags it with the things a local would notice: who it suits, how physical it is, how social, whether it's the kind of trip that needs a clear morning or doesn't mind drizzle. That's what lets Serge say "this one fits your group with a seven-year-old and a grandma who doesn't love boats," not just "tours in Cairns, sorted by rating."
A pocket editorial voice. For every listing we approve, a short Serge-style writeup goes into the product page. Not operator marketing copy, not a scraped review aggregator. The voice of the mate who's been and can tell you the honest version. You'll see these as the "Serge says" block on every tour page.
A handful of editor's picks. On the homepage we run a small, hand-curated row of experiences we rate. Six or eight. Sourced from the same catalog, but chosen deliberately, not ranked by popularity. They change as the catalog grows and as we travel more.
Context Serge carries between messages. The biggest difference from an OTA: Serge remembers you. Your dates, your van, your group, what you've already booked, the thing you mentioned about not loving heights. So when you ask for a reef trip, Serge is filtering five thousand products against your trip, not against every tourist's.
What we aren't doing
We aren't building another search box. There are plenty of those.
We aren't pretending the catalog is secretly ours. Viator built the inventory rails; that's their job, and they're good at it. Serge's job is the layer on top.
We aren't aggregating on top of aggregators. The fewer middle layers between you and the operator who runs the tour, the better the experience. Serge, Viator, operator. That's three parties. We'd rather it was two; we can't always make that possible; we're not adding a fourth.
The honest trade-off
One thing a Viator-based catalog can't give us yet is live seat-by-seat availability for every tour. We know the dates an operator is running; we don't always know exactly how many spots are left on tomorrow's 10am boat. For the kinds of trips Serge is built for (14 to 28 days on the East Coast, planning a day or two ahead) that's almost never a problem. For the narrow case where it matters (one last spot on the Christmas Day Whitsundays trip), the operator's own page will tell you the moment you tap through.
We'd rather be transparent about the trade than oversell it.
Where this goes
As we sign more partnerships, we'll layer direct operator relationships on top of the Viator base for the handful of operators we most want to guarantee. When that happens, the experience you get doesn't change: same Serge voice, same editorial, same trip-shaped recommendations. Just a cleaner line back to the operator.
For now, the short version: the five thousand come from Viator. The opinion about which three to show you comes from us.
