A consortium led by Macquarie is planning to propose a bid for the acquisition of a stake in Sydney Airport as a potential challenge to an AUD22.3 billion (US$16.7 billion) bid proposed by the IFM Investors consortium. Macquarie is currently exploring potential partners including superannuation funds to make a joint offer for the infrastructure.

The bid could include funds managed by Macquarie Infrastructure & Real Assets as Macquarie might also use its own capital from investors to submit a bid.
