Well if will be good for australians on my opinion because you can use bitcoin with no fear. There are countries out there where bitcoin is banned and other cryptos too. So yea for Australia is a big step forward because it's all about the blockchain technology.
Yeah! your right nothing to worry about. One of their purpose is to trace all suspicious transaction linked to a terrorism. that is a good.
if that will happen it will be a big impact into the BTC and to their neighboring countries.
