Following the Moscow theatre hostage crisis in 2002, Nile asked whether the then state minister of police would consider banning full body coverings, like those worn by the Chechen terrorists, from parliament and places of public gathering to prevent the carriage of weapons or explosive devices. Nile has attempted to pass bills in the NSW Legislative Council that would prohibit the wearing of full-face coverings, such as the hijab or niqāb, six times - 2006, 2010, 2011, 2014, 2017, and 2019. Five of the bills failed to be passed, with only the latest bill still not lapsed.
