Good evening,

Macquarie Asset Management and Aware Super are among Australia’s biggest infrastructure investors. But a $6 billion-plus acquisition is a monster deal by any measure and one that requires partners.

That’s why Macquarie and Aware have roped in a deep-pocketed investor to join their bid for TPG Telecom’s fibre network, which stretches 27,000 kilometres and makes about $550 million in annual earnings.

While the identity of this mystery investor remains unknown, sources told Street Talk that it has deep experience in infrastructure and has invested alongside Macquarie for years. They would help Vocus, which is jointly owned by Aware and Macquarie, split the equity cheque for the TPG deal.

TPG is within days of announcing the winner of the auction which stemmed out of a strategic review ordered nearly two years ago, the sources added.
