Property.com.au is part of the REA Group. - Realestate.com.au.
Property.com.au has Australia's largest list of properties to buy or rent -according to their website. This is because the properties from Realestate.com.au are duplicated to this site.Their site has a search function for Buyers and Tenants which leads directly to the Realestate.com.au page where the property is advertised. As it is free, if you have the access to Realestate.com.au, why not have your advertisement here, just in case some buyer searches this site before looking on Realestate.com.au. To access this site, because of its link to Realestate.com.au, you do need a third party, like ReDIY to advertise your private sale or rental.
When Domain Group claimed the title of Australia’s number one property app in 2016, REA Group was quick to respond and the matter quickly ended up in court. This latest courtroom battle is a sign of a rapidly intensifying battle between the two real estate leaders.
Whether Realestate.com.au is Australia's Number One or not, is irrelevant. It is the site that buyers and tenants go to when looking for their new home. It is the site that your property needs to be advertised on to attract the best inquiry in the shortest period of time.
