I want to report schilling by an Australian seller. Which fed. authority do I report it to.

[lokes2004]

I have today reported to ebay 2 instances of schilling by an Australian seller but from the history of this seller on ebay it is clear this has been going on for some time and likely involves thousands of dollars. What action will ebay take to remedy this and assuming that it is a fraudulent activity under state or federal law which Australian authority should I report it to?

Knowing that this has happened for so long makes me question ebay's oversight of such activity. This particular seller schill bids to an Auto maximum bid and if outbid sniffs out the new highest maximum bid and bids up to it to max the price.

If the items ends up going to the scill bid it is again put on auction and the process begins again.

This thread is reminding me why I rarely post and it will probably be quite a while till I do again.  The only reason I did post is because I have a law background which included fraud investigations and I would like to steer the OP in the right direction. Like I said in my earlier post, the fact that this behaviour happened on ebay is neither here nor there, it wouldn't matter where on the internet it occurred.  If the offender is in Australia then Australian courts have jurisdiciton over it.  I could write volumes on it but it is pretty boring.  Shill bidding is a type of fraud.  Fraud is a criminal offence.  You report it via acorn.  It costs you nothing (except your time) because the police prosecute it if there is sufficient evidence to do so.  The OP was asking where do they report it.  https://www.acorn.gov.au/ .  Don't get tied up about whether ebay is an auctioneer or whether they pay tax in Australia, those things are completely irrelevant to what the OP is asking and do not affect whether the offence of fraud has been committed in this case.  There is a big difference between civil law and criminal law.
