Australia - Senior managers of the companies building Australia's  largest desalination plant in Victoria have denied authorising covert  surveillance at the site.
Construction workers have walked off the site near Wonthaggi,  south-east of Melbourne, following allegations the project's joint  venture company, Thiess Degremont, hired operatives to spy on them. The allegations were revealed this morning by The Australian  newspaper, which says it has sources and documents about what was called  Operation Pluto. 
The newspaper says it was a secret deal between senior managers of  Thiess and the Australian Security Intelligence group (ASI), a company  run by experienced strike breaker Bruce Townsend. (more)
