Do not use Australia Fixed Rates (australiabestfixedrates.com) for anything serious. I used them since last summer for small trades and it was okay. When I deposited a larger amount and traded more, my account was flagged, my withdrawals were delayed, and I was asked to explain my trading. They treat active traders like criminals.
Pros: Great customer service|No hidden fees
Cons: No phone support on weekends|Minimum deposit could be lower
