After a process that had its origins in the 1970s an intergovernmental group suggested in 1986 Wilton and Badgerys Creek as sites for a potential second airport of Sydney. The federal government under Bob Hawke decided upon Badgerys Creek. However, over the years the project has stalled. In April 2012 Qantas chairman Alan Joyce endorsed the suitability of Wilton as a location for a potential second airport of Sydney.
