The old rail yards in Redfern is set to be transformed into a Silicon Valley-style technology hub under a secret plan to radically revitalise the city’s inner-south.

The site would have at its centre Google’s new Australian headquarters after the tech giant abandoned plans to use the re-purposed White Bay power station.

It is understood developers Mirvac are working with Google to transform a site adjacent to the Carriageworks into the hub. Google would be the anchor tenant.

The University of Sydney is also involved in the ambitious tech hub project, sources have told the Herald.
