Optus has won a contract expected to be worth $100 million to provide voice, data and mobile services to St George Bank.
The final details of the contract are still under negotiation, but initial comments indicate Optus will be managing all of the bank's communications needs.
An Optus spokesperson said it was too early to comment on whether sub-contractors would be employed under the deal. "We are still working our way through the contract at present, there are a number of issues to be discussed," the spokesperson said.
In a statement to the Australian Stock Exchange, St George chief information officer John Loebenstein said the move was aimed at holding one company accountable for communications services at the bank.
"We are changing from dealing with multiple suppliers of communications to a single organisation that will manage our total telecommunications requirements," he said.
But St George spokesperson Adam Cooke said it is unlikely Optus can provide all the voice, data and mobile services the bank will require. "Being a financial institution we have enormous amounts of data to manage," he said. "Whether that is provided by Optus or somebody else, either way the relationship will be managed by Optus."
