Federal government considering mandatory licences for telcos

A discussion paper is doing the rounds in Canberra that seeks to get a better grasp of who is a Carriage Service Provider (aka CSP or "telecommunications retailers") in Australia. Right now they simply use who is a member of the Telecommunications Industry Ombudsman, which while mandatory, not all telcos join and there doesn't seem to be any real punishment for not doing so. This is important to departments like ACMA, Home Affairs and the Attorney-General, as if they don't know who is or isn't a telco, they can't boss them around (data intercepts, network takeovers, etc.), so they're throwing out ideas for a mandatory CSP license, but acknowledge nowhere else in the world does this except for Singapore. It's pretty wild to me that the government doesn't know who is operating carriage services in the country. I just assumed you needed a license of some sort already!
