Below is the message from IB. I can trade currency futures with no problem. Enquiring further about getting permission.
"IB Australia only supports currency balances in AUD, USD, EUR and GBP, and clients are able convert between these currencies. If you hold cash balances in currencies other than IB Australia supported currencies (AUD, USD, GBP or EUR), they will to be converted into your nominated base currency.
IB Australia clients, when permissioned, can trade in any market available across the IBKR network, even those outside the 4 supported currencies above. However, upon trading any market outside the 4 supported currencies IB Australia will automatically execute Forex conversions to ensure non-supported cash balances are cleared."
