Also, ATMs aren't that good for privacy because they are usually placed in public places where there are lots of cameras around.
I don't know what it will be like in Australia, where the OP lives, but in Europe it doesn't matter. ATMs have cameras, and there may be cameras on the street but those recordings have to be destroyed by law after 30 days, according to the European data protection regulation. If you are a private individual using bitcoin ATMs to buy or sell small amounts you have nothing to fear in that regard.
The only problem has been the MiCA law, which has introduced KYC in ATMs for any amount. So they are no longer worth it. When there were exempt amounts it was worth it for privacy.
Do all those cameras work? In my country, ATMs also have cameras but some ATM cameras don't work or are so scratched or blurred that I'm sure they won't be able to see someone's face and on some ATMs the camera frames are even closed. Btw this is not common but sure exists.
We have also terminals that are used for paying bills and filling balances. These terminals also offer you to buy Bitcoin. Before Covid, you could easily pay for anything without revealing any of your information but since Covid, they changed the law because of EU's requirements and now you need to provide a phone number, then type the verification code and after that you are able to pay bills or buy a crypto with that payment terminals.
