How do Australian banks and other financial institutions combat (fight) money laundering?

thru information technology, tracking monetary payments with the help of banks and RAND services

I believe australian banks are in the business of making money. Money laundering if discovered is likely dealt with in a similar fashion to American institutions. Otherwise, I doubt if it would be an appropriate use of resources to solely seek out those who money launder. That would likely be an issue for the australian government to deal with.
