This one is very common amongst real estate agencies.
When real estate businesses consider the options available for a URL (a unique address for their website). A lot of real estate business owners would choose an abreviation of their business name.
From an SEO perspective this is not the smart thing to do. In fact a longer URL incorporating the type of service provided and the area it is provided in would make much more sense.
Why not have a look and see if there are names available like www.homeforsaleperth.com.au or www.propertymanagementgoldcoast.com.au. Names like these will rank much higher than www.rep.com.au or www.profgc.com.au (these are not real offices by the way. Just examples.
This link will take you to a site where you can check availability of .com.au web site addresses.
Good Luck
