Caller: "NBN"

Scam about upgrading the NBN, asking a lot of questions about the internet and how many devices are attached. When refusing to answer that - the caller got angry and said I was wasting their time.

An unsolicited call at home. No message was left on our voicemail.

Is it illegal to post the phone provider of these spammers?
I was once given this url where the provider is shown as well as the block of numbers,
i.e. 0290712xxx-0290779
where you can insert spam caller's number, be it spoofed or not.
