What to do?

I'm not a FOREX trader but I thought some of you may be able to help. I've sold USA real estate and now have funds in a Westpac USD account at zero interest. I'm trying to figure out what to do as I'm told AUD should fall against USD but it hasn't happened. Each AUD cent drop is worth $10,000 AUD more to me. I also see the USD is the strongest against the GBP in 30 years.

What do you see happening with the following in the next six months;
AUD vs USD
AUD vs GBP
GBP vs USD
