Google is facing a growing staff revolt, including in its Australian quarters, over plans to build a censored search engine in China.

There is little known about the program, currently named Project Dragonfly, but is reported to blacklist sensitive queries and filter websites blocked by the Chinese Government.

Google’s plan to return search to China caused global controversy in August, with over 1400 employees singing an internal petition against the move. This discourse has strengthened with Project Dragonfly, with staff claiming it would allow ‘state surveillance’ and calling for the cancellation of the program.
