Ive used Property Sale's direct  FOr sale by owner   site and like it. Their design layout is simple and they have for sale signs which are reasonably priced

Ive just started a website for Sydney and surrounding suburbs whcih we hope to build a higher density of For Sale By owner listing  or FSBO .  http://www.propertysalesdirect.com.auother  websites  seem to be spread thin across australia. Listings are free for nowH
