"Reporting scams: ASIC acts against scams involving financial products and services. The information you give us about financial scams is important. It helps us catch the operators of shonky schemes and to shut them down."

There's even one specifically set up for the "Nigerian" scams.

I would Sonofgloin take the full British pack including police response crews and cops manning the cameras.
SPAM, Pericles you seem to know a bit more than me, if bloke we could get a spam fighter I use that one, that automatically, unless you stop it,sends all spam to the investigators we would make ground.
I never respond ever it just lets them know you have an active e mail address.
As I have had nearly the same one from day one I only get the cash ones now.

ACMA also has a spam reporting facility and enforces the conditions set under the Spam Act 2003.

"The Act covers email, instant messaging, SMS and MMS (text and image-based mobile phone messaging) of a commercial nature. It does not cover faxes, internet pop-ups or voice telemarketing."
