To me, the problem may have occurred because the pixels were caught by fraudsters through Meta or Google. In Australia they do have a system for people to file their tax returns online. It's a government system called myTax. In Australia there is no outside system. There is no outside software. It's government only.
I talked to my good friend Rick Krever. Rick is a tax professor there. He is a really great tax person. He has allowed me to use his name. He told me that he thinks most of the private software packages are integrated into bookkeeping, and that's why some people will use the private system, but myTax has been checked and it's completely safe.
