Then we moved to cash, and for many years people used cash to fulfil transactions. However, we're quite quickly moving to a cashless society. In fact, for me personally, I very rarely carry cash, which gets rather embarrassing when raffles are put in front of my face. I'm sure many members of this House and many people at home do not carry cash. So we're particularly reliant on financial systems, financial transactions, and we've heard that there is $35 billion a day worth of transactions going through. Now, it's absolutely vital that this system is robust, that it is sound, and that it is efficient. So as a Government, and, in fact, as a Parliament, we're doing the right thing by putting some regulation in place.
