I called back number (02) 9062 3398 rang once then gets disconnected automatically.

if you ring back and its automatically disconnected then its a one use number used by charities and companies who bulk buy one use numbers from Telstra...wasnt worth answering as one use numbers are always selling something.

Similar with the third comment. A gentleman from Smarter Australia or something. Seemed like just a telemarketing call.

I had a call today as well knew my first name said their name and advised they were calling from Safety Australia or something very hard to hear said I didn’t know them and hung up
