Even then this should only be available for law enforcement, not local fucking councils!
How did we get into this mess?
Illegal advertising - get the details of the number on the poster.
Unregistered pets - maybe they have an 'if found please call ...' tag on the pet, but no pet registration.
People dumping stuff illegally - if you were dumping general household/office waste, you'd probably have letters or bills with your address on it already, but I can think of scenarios where they might only have your email address to go on.
Wiretaps (ie: obtaining content) do require a warrant, and in the state of Victoria, where this is, half of all such applications for warrants are rejected by the magistrate. Getting the name and address of the owner of a phone number is a humdrum law enforcement issue, and really councils should have that power. Getting the list of calls made or where emails have been sent is a more serious violation of privacy (instead of "who owns this?" it's "what do they do with it?"), and I imagine that there's simply a legal loophole there.
The article has an amazing lack of detail and follow-through.
Even if we pretend for 10ms that surveillance is even remotely justifiable and is the only option to deal with pet ownership and littering (!), I am immediately concerned about what accountability and oversight measures are or aren't in place. Local councils are already notoriously rife with corruption, incompetence and abuse of process - that it's so easy for that sort of culture to breed indicates fundamental problems which desperately need addressing before this kind of power could possibly be entertained for such weak institutions...
Astounding.
