The Australian Transaction Reports and Analysis Centre (AUSTRAC, for short) is like a special team of people who work to keep Australia safe. They keep an eye on the money that moves through our country to make sure that people are not doing bad things with it, like buying or selling drugs, financing terrorism, or other illegal activities.
Imagine a big bank where people deposit their money. AUSTRAC works together with that bank to collect information about the people who deposit money and the people who withdraw it. They use special computer programs to analyze this information and look for anything that seems suspicious or out of the ordinary.
If they see something that looks bad, they will investigate it further and try to stop the bad people from doing any more harm. They also use this information to help the police arrest criminals and prevent crime from happening in the future.
So, in short, AUSTRAC is like a team of heroes who work to protect Australia by keeping an eye on the money that moves through our country.
