Aussie SSA/ATO Robocall

I received a strange robocall in a perfect Aussie accent, claiming someone was proceeding with debt recovery bankruptcy or something that was going to affect my Tax File number , suspension. It was strange as it made the impression it was a private company, not a govt agency. It asked to press 1 at the end to connect but nothing happened. The return number was an Australian mobile 0457 072 036

I was excited to talk but the call back did not work and pressing 1 did not get me anywhere
