I earn income outside of Australia which doesnt need to be declared inside Australia. The audit confirmed that (eventually).
Blacky, the AFP can access the travel records of everyone going back 10 years. They can go back longer if they submit a special request. AUSTRAC also have access to this info to track money laundering, crime and tax evasion. Both agency's share with the ATO. I'm not sure why an audit was needed to confirm you don't pay tax in Australia on income earned overseas? You're a non resident for tax purposes so any income you earn overseas, e.g.the rent from your condo in Manila, doesn't need to be declared in Oz. This has always been the case.
Jonesy, I use Tor because my job requires that I protect my communications, investigations, and intelligence gathering. We also request whistleblowers and activists use it to safely report on corruption, abuses and problems in danger zones.

Yes the ATO can monitor sites like these but are unable to act against individuals because they don't who you are or where you live. I doubt Simon or other administrators have been asked by the ATO for someone's IP addrss and even if he has and gave it to them, the person could be using a proxy or VPN so they'd be untraceable.
