NBN Co has cemented its position as the largest Australian corporate issuer in Green Bond format through its latest A$750 million Green Bond issuance in the domestic debt capital markets.

The 10-year fixed rate benchmark Green Bond issuance, which settled on 6 March 2025, is one of the largest Australian Dollar denominated 10-year Green Bonds issued by an Australian corporate issuer.

This transaction brings NBN Co's total outstanding Australian Medium-Term Notes (AMTN) to A$6.9 billion and means that NBN Co has now raised a total of A$7.4 billion equivalent of Green Bonds in the domestic and international markets.

The latest Green Bond was issued under NBN Co's A$10 billion AMTN Programme. Proceeds from the Green Bond issuance will be fully allocated to eligible green projects undertaken as part of the company's commitment to energy efficiency in line with its Sustainability Bond Framework, released in June 2024.

The latest debt raising follows a seven-year benchmark Green Bond, which raised A$750 million in August 2024.

NBN Co raised A$850 million in Green Bond format in August 2023 and issued its first Green Bond of A$800 million in April 2022.

In March 2024, NBN Co successfully raised EUR 1.3 billion (A$2.16 billion equivalent) from its second Euro Green Bonds issuance in the European debt capital markets.

This followed NBN Co's inaugural European Green Bond issuance of EUR 1.35 billion (A$2.1 billion equivalent) completed in March 2023.

The latest Green Bond transaction is currently NBN Co's longest tenure Australian Dollar denominated bond. It has expanded NBN Co's Australian interest rate curve and further diversified the investor base.

Fiona Trigona, Executive General Manager, Group Treasurer at NBN Co, said:

"We are very pleased to receive such a positive reaction to our latest offering. The transaction was well supported by a range of investors both domestic and offshore.
