Realtair vs Rex Software (2026): Which Australian Real Estate Platform Wins?

Two of the strongest local names in Australian real estate technology do almost opposite jobs. Realtair runs the sales process — auctions, offers, deposits, signing. Rex Software runs the database — contacts, pipeline, prospecting, and now a layer of AI that captures your day for you.

So "which one wins" is the wrong question to ask first. The right one is: which problem is actually costing you money? If it's auction day chaos and deposit administration, the answer is Realtair. If it's leads going cold because nobody updated the CRM, the answer is Rex. Most serious agencies will end up running both.

This piece compares them on the things that decide a real budget — price, what each does in practice, Australian fit, and who should buy which. We scored both in full reviews; we cite those scores here rather than re-running them.

Quick look

Two purpose-built Australian products, both scoring full marks on Australian fit. The score gap is real but it isn't a head-to-head verdict — they're graded against different jobs. Realtair earns its extra three points on feature depth and published, transparent pricing. Rex carries the heavier pricing penalty because it won't tell you what it costs.

What it costs in Australia

This is the cleanest difference between them, and it matters before you even look at features.

Realtair tells you the price: $189 per agent per month, inclusive of GST, plus a one-off $499 activation fee. You can budget from a web page. The activation fee is the one sour note — there is no obvious reason for a setup charge on top of a subscription, and sole operators feel it.

Rex publishes nothing. Its plans page lists three tiers — Starter, Professional, Enterprise — with no prices and a "Request pricing" form (checked 8 June 2026). Third-party listing sites quote indicative figures, but they conflict — roughly $99 per user per month at the low end, $200-plus at the high end — and none of those are vendor quotes. You cannot compare Rex on cost without booking a demo. For a publication that exists to tell Australians what things cost, that opacity is a genuine mark against it, and it's the single biggest reason Rex sits a band below Realtair on value.

On price and transparency, Realtair wins outright. You know what you're paying.

What each one actually does

Realtair: the transaction engine

Realtair organises around the three ways Australians sell property — auction, private treaty, and timed auction — and runs each end to end.

• Hybrid auctions. It runs in-room and remote bidding simultaneously from one interface, with digital bidder registration, live bid updates to remote bidders' phones, and vendor bids handled inside the flow. Most platforms do either in-room or online. Realtair does both.
• Trust-account deposits. Digital deposits flow straight to the agency trust account — not a third-party escrow you reconcile later. This is rare, and it's where Realtair earns its keep.
• Pitch and Sign. Vendor presentation decks and document execution (listing agreements, authority forms) are built in, not bolted on, and included in the base subscription.

One platform takes you from vendor pitch to signed contract to collected deposit. The alternative is four or five separate subscriptions that don't talk to each other.

Rex: the database brain

Rex is a full CRM — contacts, pipeline, campaigns, appraisals, listings, reporting — with a 2026 AI layer on top.

• AI Admin (open beta). You tell Rex what happened by voice or text after an inspection, and it logs the note, updates the contact, sets a follow-up, and drafts the email. It removes the friction between what happens in the field and what gets recorded — the single most-complained-about task in agency life.
• AI Prospecting. It ranks your existing contacts by likelihood to sell, with context for why each rose to the top and suggested talking points. Prospecting becomes data-led rather than gut-feel.
• Natural language queries. Ask "show me buyers who looked at three-bedroom houses in Mosman last month" and Rex returns the matches — no report builder required.

The caveat: AI Admin is still in open beta, and two further features (AI Nurture, AI Manage) are flagged for late 2026 and not yet live. You're partly buying a roadmap.

On feature depth for its own job, each one wins its own lane. Realtair scores 5/5 on depth for transaction workflow; Rex scores 4/5 on a CRM whose flagship AI is still in beta.

The use cases: who does each one serve

They overlap less than their category label suggests. Realtair is the sharp tool for the sale itself. Rex is the system of record for everyone you'll ever sell to. The honest position for many mid-sized agencies is that these aren't rivals — they're two layers of the same stack.

Australian fit

Both score 5/5 on Australian Fit — the joint best in this category — so the gate isn't the deciding factor here. But they earn it differently.

Realtair is built around specifically Australian sales mechanics: vendor bids, cooling-off waivers, and trust-account deposit collection are part of the product, not afterthoughts. It bills in AUD inclusive of GST and offers six-day support that covers the Saturdays auctions actually happen on.

Rex is built around the Australian agency itself: Brisbane-built, trusted by more than 10,000 AU/NZ agents, with a roadmap shaped by local workflow conventions rather than US or UK ones.

One shared caveat: neither vendor publishes a current data-residency statement we could verify — both privacy-policy URLs returned 404s when we checked them in early June 2026. Australian hosting is likely for both, but if onshore residency is a hard requirement under the Privacy Act for your agency, get it confirmed in writing before you sign — from either vendor.

Per the Australian Fit gate, both clear the Australian Fit gate (≥ 4/5), so neither's local fit caps its star rating. The score gap between them is about depth and pricing transparency, not Australian fit.

The verdict: who picks which

Pick Realtair if you run auctions. Full stop. If your week is built around Saturday auctions — live, online, or hybrid — nothing else in this market handles them at this depth, and the trust-account deposit flow saves real compliance hours. At $189/agent/month with transparent pricing, an agent running three or more campaigns at once recovers the cost easily. It's our higher scorer at 22/25, and the right answer for transaction-heavy agents.

Pick Rex if your problem is the database, not the auction. If leads go cold because the CRM never gets updated, AI Admin's voice-to-CRM capture is the fix — and it's a genuine one. Rex is the strongest AI-enabled real estate CRM in the local market at 19/25. Just go in knowing you'll need a demo to learn the price, and that the full AI suite is a late-2026 story.

Run both if you can. They're complementary, not competing. Realtair handles the sale; Rex holds the relationships before and after it. The mid-sized agency that pairs them gets transaction depth and database intelligence in one stack — at the cost of two subscriptions and two onboarding efforts.

Honest limitation: we can give Realtair a clean value verdict because it publishes a price; we cannot do the same for Rex until it does. That gap shapes the scores as much as the features do — judge Rex on its features, but budget for the demo before you commit.

Frequently asked questions

Which is better for Australian agents?

They do different jobs. Realtair (22/25) wins for the sale itself — auctions, offers, deposits, signing. Rex (19/25) wins for the database — contacts, pipeline, voice-to-CRM admin. Both score 5/5 on Australian Fit. Pick by which problem is costing you money.

Which is cheaper in AUD?

Realtair, because you can actually see the price: $189/agent/month inclusive of GST, plus a $499 activation fee. Rex publishes no prices at all — you have to book a demo for a quote.

Is there a free plan or free trial?

No. Realtair advertises no free trial, and we found none for Rex. Both are sales-led.

Can I run both?

Yes, and most mid-sized agencies should. They're complementary, not competing — Realtair handles the sale, Rex holds the relationships before and after it.

Do they store data in Australia?

Both are Australian-built (Realtair in Sydney, Rex in Brisbane) but neither publishes a current data-residency statement — both privacy pages returned 404s when checked. If onshore storage is a hard requirement, get it confirmed in writing before you sign.
