Australia's opposition doesn't oppose national security measures in order to avoid being made to look disinterested in the nation's defence.
No, Australia's opposition doesn't oppose national security measures because influential foreign governments have as much dirt on them as they do on the neo-nuts. No one has forgotten the lessons of the Whitlam government. Combine this obscene legislation with the data sharing legislation passed during the Rudd era all tied up with with warrantless access and we have high treason out of Canberra, again. Have to wonder if ASIO/AFP haven't completely lost the plot as they appear to be a far greater threat to Australia than the cartoon villains the US keeps creating. This trove of data will expose friend and foe alike.
