We've just received a letter from the Australian Bureau Of Statistics telling us  our household has been selected for a  Wellbeing And Lifestyle Survey. Our names do not appear in the address on the envelope, just an "Obligation ID".  And, apparently, due to the Covid pandemic the survey has to be done online.  There is a step by step guide to accessing the appropriate website etc. 

To be honest, I think it  probably is genuine, but I am seriously thinking of ignoring it, and when they chase us up saying we assumed it was just another scam, phishing for our personal details.
