Optus has secured a $1.3 billion credit facility with 11 banks for general corporate purposes.
The new credit agreement is part of its parent company Singtel's credit facilities with international banks totalling S$3.5 billion.
The Optus Finance agreement is a three-year $1.2 billion revolving facility with 11 banks, including Westpac, ANZ and the Commonwealth Bank.
Bank of America, Barclays Bank, The Bank of Tokyo-Mitsubishi, BNP Paribas, Citibank, HSBC, JP Morgan Chase Bank, Mizuho Corporate Bank and the Oversea-Chinese Banking Corporation are also involved.
In Singapore, SingTel Group Treasury entered a three-year S$2.16 billion revolving credit facility with 12 international banks.
The funds will be used for general corporate purposes, and to refinance existing facilities, according to a company statement.
This follows Optus' $800 million deal, announced last week, to progressively migrate its hybrid fibre coaxial cable customers to the NBN as it is rolled out across the nation.
