I'm pretty sure it can be via EgoPay. You transfer the funds from Cryptsy to EgoPay, and then EgoPay allows to wire transfer to the Australian bank account.

I've done the reverse process to get my AUD to Cryptsy (tried using Cointree first but they were considering adding GST to the transaction at the time).

I'm wondering if there's a cheaper/better way than EgoPay? Would it be better to convert the USD to BTC and transfer it somewhere else for conversion back to AUD?
