He checked Australian Government site before his overseas trip in DEC. The website noted the Names on Vac certificate have to match names on the passport. He contacted Service Australia & had his Health card & his Vac cert modified to match his Canadian & Australian passport

" 4. Follow the steps to verify your vaccinations and passport details. You may need to update your middle name in the passport details screen to match what is on your passport."
If Australian Vac cert has to match the names on the passport I would assume same is required of International travelers.
I had a similar issue in that I have a double barrel surname but the second surname was only added when I was about 4 months old by which time I had already been registered with Medicare. As I've never needed to change it my Medicare name had always just been as it was the day I was born. The Services Australia people actually changed it over the phone and rang the passport office while I waited to confirm the correct details. It actually was pretty quick; I had been expecting it to take weeks.
