Domain or RealEstate.Com.Au ?

When looking for a property to buy or rent, it is worth looking at both Domain and REA.  Note that for REA, advertisements can only be placed by real estate agents.  If an individual landlord or seller wishes to advertise, then only Domain will accept the advertisement.  Accordingly, Domain will have different (and possibly more) listings than REA, and often at a better price or rent (because agents fees are not being paid.)
