He said he won’t force anyone to get the jab, Gov is making it free and voluntary. Fed Gov will make entry to Australia mandatory tho so don’t travel abroad if you don’t want it.
As we all know states control their own border each state could require vaccination proof before entry if not just travel inside your own state for ever.
There are ways to make this voluntary uptake of it mandatory without making it mandatory from a fed gov perspective. Just be prepared not to be able to do a lot if you don’t take it.
