Australia Real Estate Data
Australia’s online property market is a duopoly led by realestate.com.au and Domain, with realcommercial.com.au for commercial and Trade Me serving neighbouring New Zealand — and PropAPIS extracts all of them through one API. realestate.com.au alone drew a record ~161.8M visits in October 2025, reaching ~13M Australians (SAHM Capital ).

Market overview
The Australian residential market is a tightening duopoly. REA Group — majority-owned by News Corp — operates realestate.com.au (the clear #1) and realcommercial.com.au (commercial), and also owns the PropTrack AVM/data arm. In FY2025 REA Group posted 15% revenue growth and set a record audience, reaching ~13.05M Australians and ~161.8M visits in October 2025 (Online Marketplaces ; SAHM Capital ).
The #2 group is Domain, which was acquired by the US-based CoStar Group in an ~A$3B takeover that completed on 27 August 2025 (CoStar press room ). The Domain group bundles Domain, Allhomes (the Canberra/ACT leader) and commercialrealestate.com.au; combined Domain and Allhomes reach ~9M monthly audience and ~55M visits/mo (Domain media release ). The duopoly tightened further in 2025 when View.com.au, the best-funded recent challenger, announced its closure (Online Marketplaces ).
Data richness is led by realestate.com.au (price history, agent info, photos, geo, sold data and suburb insights, plus the PropTrack AVM) and Domain (similar fields with price guides and sold data). The commercial portals add commercial leasing, sold listings and price trends. Across the Tasman, Trade Me Property is the New Zealand leader, with ~39k residential listings reported in January 2025 — a five-year high (Trade Me ); in June 2025 Trade Me merged Stuff Digital’s property section into Trade Me Property to consolidate NZ listings (RNZ ).
