"The tsunami ... that comes at us each year is bigger than the one before," said Wright, adding that traffic over the 4G network is growing 20 per cent per month.
Telstra has dedicated $1.2 billion to its mobile network for the 2012-13 period. The telco plans to build 1,000 new 4G base stations this year and cover two-thirds of the population with 4G by June, said Brendan Riley.
Telstra CEO David Thodey has said recently that the Apple iPhone 5 has helped drive 1.5 million customers to 4G. He said the telco is trying to migrate as many customers as possible to 4G because it's a cheaper way to carry data.
Vodafone Hutchison Australia, the only major Australian telco without 4G, said yesterday that it's trialling LTE in eastern Sydney. Vodafone's network is expected to go live later this year.
