NBN Co raises $1.2 billion on European debt markets

NBN Co has raised €750 million (A$1.2 billion) from its second Euro Sustainability Bond issuance in the European debt capital markets.

Net proceeds from the transaction will be allocated to investments into the deployment of nbn network energy-efficient fibre and the nbn Fixed Wireless network.

This issuance brings NBN Co’s total outstanding green or sustainable financing to approximately A$10.7 billion equivalent, making NBN Co the largest Australian corporate issuer in green and sustainability format in the domestic and international debt capital markets, the company claims.

This issuance also represents the 11th transaction in green or sustainable format by NBN Co since the launch of its first Green Bond in 2022, NBN Co said.

In May 2025, the company’s first ever Sustainability Bond issuance raised €700 million in the European debt capital markets.

In March 2026, NBN Co’s inaugural domestic Sustainability Bond issuance successfully raised A$850 million.

NBN Co's Sustainability Bond Framework, issued in 2022, stated that NBN Co "will contribute towards sustainable development through Green, Social and Sustainability Bonds by earmarking the proceeds to finance or refinance eligible green and social projects that deliver positive environmental and social outcomes".

“Our Sustainability Bond raisings enable us to fund investments in nbn network energy- efficient fibre, which helps deliver a more resilient network and also in the fixed wireless network which plays a crucial role in helping to enable connectivity in regional areas,” said Fiona Trigona, EGM, group treasurer at NBN Co.

“We were very pleased by investor interest in our Sustainability Bonds issuance in what remains a volatile market due to uncertainty resulting from geopolitical challenges and the ongoing situation in the Middle East.

“The success of our latest issuance in the European debt capital markets illustrates strong investor appetite for Australia and for NBN Co’s credit."
