After Guardian investigation, department launched internal inquiry. Now it has referred matter to watchdog

The NSW transport department has referred its purchases of tens of millions of dollars in environmental offsets in western Sydney to the Independent Commission Against Corruption for investigation.

The referral to the state's corruption watchdog follows a Guardian Australia investigation that revealed that a company known as Meridolum No 1 made more than $40m selling offsets for infrastructure projects that Eco Logical Australia, which employed two of Meridolum's directors, provided offset advice on.
