This is a list of Australian Taxation Office scammer numbers. They normally block silent numbers and will block the number you call on once they know you’re baiting them. They only answer during Australian business hours, but sometimes they answer on public holidays because they don’t know our public holidays too well. This is a big list, but some of the numbers might go to the same scam center, so if your number gets blocked from calling one scam number, you might also be blocked from calling a few other numbers if they go to the same call center. They’re NOT free calls. If dialing internationally you should drop the first 0 and add the country code for Australia is +61:
