Realestate.com.au and Domain.com.au are undoubtedly the best sites to advertise on. These have been discussed, at length on previous articles.
There are other dedicated Real Estate sites that attract some enquiry. Advertise on these minor ones, by all means, but you really need to have your property advertised on Realestate.com.au. and Domain.com.au for the greatest exposure, to get your private sale to a private sold.
Their site is not informative about who they are or when they commenced. Homesales.com.au offers Licensed Real Estate Agencies access to advertise property listings across their platform for free. Because of this, they do have many properties for sale and for rent. All properties on this site are an extra bonus, for Sellers and Landlords who pay for marketing and advertising with an Agency. The same properties are all on Realestate.com.au and Domain.com.au. When advertising with ReDIY, your property will be advertised on this site as well as 9 other sites, including Realestate.com.au and Domain.com.au. All for a one off, low fee. The advertisements remain until sold. See the ReDIY homepage for our fees and the full list of the sites that you can advertise on, when choosing ReDIY.
