Australia's off-market property segment has quietly produced a cluster of proptech platforms that are worth knowing about. Each takes a different approach to the same problem: helping buyers find properties that don't appear on Domain or realestate.com.au.
Here's an honest look at the landscape — who's building what, and what it means for buyers.
Homer started life as KoalaData, a Chrome extension born out of frustration with the lack of transparency in Australian real estate. The original tool did something simple but powerful: it inferred how long a property had been on market by analysing photo upload dates.
KoalaData grew to 12,500+ installations and 5,500 weekly active users before merging with Homer in late 2023.
Today, Homer is trusted by 40,000+ Australians. Its core feature overlays hidden data directly onto Domain and realestate.com.au listings: the actual price from the Statement of Information, failed auction results, rental history, and gross rental yield calculations. The premium Agent Insights feature reveals patterns across an agent's past listings — pricing movement, timing, and how properties are typically sold.
Homer is a transparency tool rather than an off-market discovery platform. It doesn't help you find off-market properties, but once you find one, it helps you negotiate from a position of knowledge. That's a valuable complement to any property search.
Listing Loop has one of the more interesting origin stories in Australian proptech. Founded in 2018 by Rhett Dallwitz and Andrew Meehan, it raised over $5 million across two funding rounds and was explicitly built as a marketplace for pre-market, off-market, and secret listings.
At its peak, Listing Loop was delivering 750,000+ property match alerts to buyers and tenants each month. The platform matched buyer requirements against off-market listings in real time, operating across four apps: Buyer, Admin, Agency, and Private Seller.
The significant development came when Listing Loop was absorbed into Lendi Group, the parent of Aussie Home Loans. Dallwitz transitioned from CEO of Listing Loop to General Manager of Agent Services at Lendi Group. The technology was relaunched as "Aussie for Agents" — a platform offering agents free unlimited listings across off-market, pre-market, and on-market properties.
The business model shift is telling. Listing Loop struggled to monetise listing fees from agents. Aussie for Agents solved this by making listings completely free — and monetising through Aussie's mortgage business instead. When a buyer finds a property through the platform and needs a home loan, Aussie captures that revenue.
It's a clever model that aligns incentives: agents list for free, buyers discover properties earlier, and Aussie originates home loans. The question is whether being embedded inside a mortgage company changes the user experience — and whether buyers trust a platform that's ultimately trying to sell them a home loan.
Property Whispers is Australia's original off-market matching platform, conceived by Liane Fletcher in September 2015 and launched nationally in May 2017. Fletcher, an award-winning innovator and licensed real estate agent, designed it as "a dating website for property" — and that metaphor actually captures the model well.
Unlike browse-and-search platforms, Property Whispers has no browsing. Buyers register their requirements (location, budget, property type), and when a match occurs with a listed property, both buyer and agent/seller receive each other's contact details instantly. It's a blind matching system where neither side sees the other until there's mutual relevance.
The platform has created 20,000+ matches since launch and has won multiple awards including Best Off-Market Property Sales Platform (BUILD 2024) and Real Estate Platform of the Year (Australia Prestige Awards 2024).
Pricing is modest: free for buyers, $99+GST per listing for agents, $139+GST for private vendors. No commission on successful sales.
Property Whispers' strength is its purity of focus. It does one thing — match buyers with off-market properties — and does it without the noise of a marketplace. The trade-off is scale: without browse-and-search, it's harder to build the casual buyer engagement that drives growth.
OpenBA is the newest entrant and takes a fundamentally different approach. Rather than serving buyers directly, it's an AI-powered SaaS platform built specifically for buyer's agents.
Founded by a team with backgrounds at Domain, Rokt, Airtasker, and Zip, OpenBA automates the most time-consuming parts of running a buyer's agency:
The platform's website monitoring feature is particularly relevant: it does what many off-market aggregators do (scrape agency websites for new listings) but packages it as a tool for buyer's agents rather than for buyers.
We built offmarket.now to fill a specific gap: a free, map-based tool that surfaces pre-portal and off-market listings and delivers postcode-level alerts to buyers.
We're not trying to replace buyer's agents — in fact, we think REBAA-accredited agents are the best way to navigate off-market transactions. We're trying to democratise discovery: giving every buyer the same early access to listings that previously required agent connections.
The platforms above are each doing valuable work, and we see them as part of a broader ecosystem rather than direct competitors:
