"They are not fixed maps, they are generated and rendered on the fly, so if it's for First National [real estate] we can make them look like their maps," he said.

An early adopter of the technology is Dural First National real estate on the outskirts of Sydney.

Managing director Pauline O'Neill said having access to property information on her 3G mobile phone saves a lot of time when on the road with potential customers.

"I take the phones out with me and I can go into the property and show my client the size and shape of the land," O'Neill said. "I can also show clients the nearest schools and doctors, it comes up on the screen."

The application also enables searches via street name and returns four maps, including the street block and suburb. It can also identify dams, buildings and sheds on properties.
