"We used to use Google but now we have a better system," O'Neill said. "I can show clients stuff they don't even know about their property. We can also look at listings other agents have in the area and use this to compare values and will shortly be able to show sale prices on the screen."

A 30-year real estate industry veteran, O'Neill said using a mobile application allows her to compete with "much younger" local rivals.

The solution has also eliminated the need for a laptop to be taken out to properties, because O'Neill can see if changes have been made on the Web through the phone.

"The key benefits for me are image and cost," she said. "Until recently I was paying upwards of A$600 (US$452) a month for data. MapShed costs $3 a month so there is no bill shock, but I still pay A$300 to A$400 to service providers."

O'Neill said the biggest problem is the quality of service on Hutchison's 3 network.
