"They've taken out something like 700 meetings a year and are now at a point where they're saving about $5 million per annum just in travel costs alone."
A growing area with much potential is M2M communications, said Geason.
"Machine-to-machine is one of the most interesting, exciting yet under-explored opportunities here in Australia."
Coca-Cola, one of Telstra's customers, has Telstra SIMs in all its vending machines to notify the vendor when it's time to restock, Geason said.
"The opportunities are absolutely endless," he said. "I think that will be a very significant growth sector within technology over the next five years."
While mobile broadband continues to improve, Geason said he does not see it ever completely replacing fixed connections.
"Fixed networks will remain incredibly important," he said. "Mobility only runs the distance from the tower to the device. Everything else is on a wireline network ... The future is how we combine the two."
