The network expansion plans include 3 building new coverage where there is currently high roaming and 3G roaming on parts of Telstra's 850MHz network.
These initiatives are claimed to increase 3's 3G network presence from the current 56 per cent coverage as of today, to covering some 96 per cent of the population and are in addition to 3's existing infill site program.
The telco says the new site build is commencing this year in areas of current high roaming for 3's customers including Newcastle and the Central Coast in NSW and the Mornington Peninsula in Victoria. Around 50 sites will be complete by the end of the year, it says.
Roaming arrangements for 3G roaming on parts of Telstra's 850MHz network will be in place during the second quarter of next year.
"Plans to extend 3's 3G network mean that our customers will be able to access their 3G services in far more places, and with the appetite for services like the internet on the mobile growing rapidly, it makes good sense," said Nigel Dews, Chief Executive Officer, Hutchison Telecoms.
