On 10 April 2012, workers downed tools on the new Sydney harbourside development, Barangaroo, following the discovery of asbestos.
The Secretary of the CMFEU, Brian Parker, expressed concern about the discovery.
Only a small amount of asbestos exposure can lead to a worker developing mesothelioma, the asbestos related cancer, in future years.
Lend Lease, who are developing the site, stated that safety was the highest priority.
