Labor renews calls for national integrity commission over Sydney airport offsets

Mark Dreyfus says corruption watchdog needed to investigate government buying $30m in offsets related to new airport

Labor has strengthened its call for a national integrity commission, saying it is needed to investigate the Morrison government's purchase of more than $30m in environmental offsets related to the development of the western Sydney airport.

The shadow attorney general, Mark Dreyfus, made the call after the New South Wales transport department referred its purchases of $50.6m in offsets from the same western Sydney properties to the state's Independent Commission Against Corruption for investigation.
