Google has added a real estate search feature to its Google Maps service in Australia, letting potential home buyers view available properties across all real estate companies in a particular area.

Google has worked with numerous property companies to provide hundreds of thousands of homes for sale and rent, which are displayed the map by small red circles.

A property search can be refined by price, type of property, number of bedrooms, number of bathrooms, and parking availability.

Clicking on a small red circle will display information about the listing and the contact details of the agent will be displayed.

Google spokesperson Andrew Foster says that even though Australian home buyers already use Google Maps for research, the new feature now puts everything in one place.

"Given the importance of location to a home search, we've made it easy for home buyers and renters to see listings that match their criteria on Google Maps even as they pan and zoom the map to different areas," Foster said.

Other tools on Google Maps include driving directions, Street View and public transport information.
