Commercial property heavyweight Dexus has completed its flagship Quarry industrial estate in Greystanes in Sydney's west after securing retailers Beaumont Tiles and Coco Republic and packaging group Orora as the final tenants.

The 70-hectare former stone quarry, which Dexus has been developing with its joint venture partners for over a decade, is now fully leased amid the strongest conditions seen in the Sydney industrial leasing market since the GFC.
