Brisbane City Council has requested citizens’ metadata from telecoms companies, prompting calls of "Big Brother" from the council's Labor opposition.

According to the telecoms industry, the BCC is among more than 100 bodies making thousands of requests for details of numbers called by phone users, their location, the length of calls, email addresses and other information telcos are obliged to keep for two years under national security laws passed in 2015.

Council opposition leader Peter Cumming says he does not recall any discussion or debate about the use of metadata laws in council.
