Confirmed: Govt Intercepts can't identify source from large Telcos mobile internet

From long-running posts on problems with Carrrier-Grade NAT (CGNAT) by Geoff Huston of APNIC, I'd previously posited that the current call for "metadata retention" is driven by Intelligence Agencies needing to identify sources. This SMH article points to a recent 9-page PDF Consultation Draft, extracts below. Stilgerihan in ZDnet points to both the SMH piece and a 16-pg 2010 Draft, heavily redacted when first released under FOI.
Links: Brandis' follies, and metadata catches downloaders not serious crims.

CGNAT is only used by the largest Telcos. Twenty years ago, Optus used NAT for its Cable (HFC) internet and Huston writes about mobile Internet now using private 10-Network addresses internally.

Brandis's stumbling and bumbling has given away more State secrets than Snowden.

Expanding on my previous comment that only ordinary citizens, no serious criminals or terrorists, will be caught by the mismanaged & mangled "thought bubble" of Brandis on metadata retention .

Brandis is a fool or knave, probably both. he's given away two important intelligence secrets, he's trying to secretly "backdoor" his draconian "Copyright Piracy" laws and he's covertly, possibly unconstitutionally, trying to push costs of Government Intelligence operations onto the private sector.

New 'metadata' laws will only catch ordinary folk, NOT terrorists or serious criminals

Life Matters on RN ran a session today on the proposed Metadata legislation. I tweeted a comment, but it didn't make the cut.

First, what's metadata?
It's "Data about Data", an inexact, mutable and undefinable concept, best described as "it varies on what we have, who wants to know and what the law says it is".
