No Australian bank is interested in handing over hundreds of coins at a time to a customer, unless they feel that they (or you) have a good reason to do so.
They see it as just a waste of time for them, especially if they see a line of 20 customers waiting behind you.
Fortunately, there are no silver coins to be extracted from the circulating currency in Australia. The only scarce coins that may be taken from circulation are mainly in the 50 cent and dollar denominations, but they are common enough after recent release to not to have to go the the bank for them anyway.
I guess that may be the result of deliberate minting and issue policy.
