My understanding is that this information is only available through Medicare via the MyGov website so you may need to renew your Medicare card. I just checked mine and it shows my vaccination. Elsewhere it states that I've only had the first doseThe rationale for asking is that I'm intending to emigrate to Canada after October. I don't have a mobile phone, and my Medicare card has expired, so if Canadian Immigration wants to know if I've been vaccinated, can I show them a printout, or is it all digital?
I'm unaware of how you may be able to get a printout and wonder how acceptable that may be as proof for another country?
