Next step for westpac may be accepting bitcoin, if that happen it will be nice to get atleast one bank that accept bitcoin. 
banks CANT
its in their regulations
again
BANKS CANNOT OFFER BITCOIN AS A PRODUCT OR SERVICE DIRECTLY TO CUSTOMERS!
BANKS CANNOT HOARD BITCOIN DIRECTLY,
in short a bank will never, under current regulations ask a customer for a bitcoin address or display to customers a bitcoin address to deposit or withdraw funds.
thats why you have to rely on third party services
