Telstra has rejected calls from Singapore Telecommunications Cable & Wireless Optus for Government intervention designed to increase Telstra's subsidy to companies using the Telstra network.
"Singapore Telecommunications has just paid $14 billion to take over Optus so they can certainly afford to pay a fair price for the use of Telstra's Australian network," Telstra CEO Ziggy Switkowski said.
"Attempts by SingTel Optus to pressure the Government into intervening on Telstra's legal rights and commercial responsibilities to shareholders are quite inappropriate."
Switkowski said SingTel's proposal would shift hundreds of millions of dollars from Telstra shareholders to SingTel and other international telcos.
"Singapore Telecommunications is not a little Aussie battler -- it is an international company attempting to opportunistically influence the Australian Government at a politically sensitive time."
Switkowski said that after a decade of competition, suggestions that Telstra remains a monopoly were "ridiculous".
