I just saw this:

Victorian Premier Daniel Andrews has confirmed unvaccinated shoppers will be locked out of attending non-essential retail premises from November 24, the date the state is expected to reach its 90 per cent double dose vaccination milestone for people aged 12 and up (not 16 and up). This policy had been flagged last month and it marks a change to the existing, more permissive rules. Since October 29, unvaccinated and vaccinated shoppers alike have been able to visit non-essential retail stores.

I think this is what we need to look at doing more generally.
