ASIC is the biggest joke of regulator ever! I was also scammed by a n Australian company, and when i complained to ASIC, they said it is not their job to get my money back as they are only a regulator. WTF does this mean?
Also, if we can't rely on a regulator at least investigating our cases/disputes with brokers, then the term REGULATED doesn't really mean anything.
The only thing I can think of to counter act this, is that you split your money across several brokers and consider the total amount you have with all of them as one account, then for example you can trade one account and copy the trades to the other accounts. If one broker doesn;t honor the withdrawals, hopefully the others will.
