This document discusses freedom of speech in Australia and concerns around recent changes to security laws that could undermine civil liberties. It provides background on Amnesty International and defines freedom of speech as the right to hold opinions without fear of punishment. Recent anti-terrorism laws passed in 2002 are then critiqued for allowing detention without charge, denying access to lawyers, and potentially being used against political dissent rather than just terrorism. The conclusion warns that giving up essential civil liberties in the name of security threatens the very foundations of society.
