This post is pretty clearly anti-vaxination propaganda. There is nothing in the article attached to the Twitter post to suggest that the incident related to vaccinations, never mind the fact that Australia does not have a requirement for mandatory vaccinations. This post is misleading and dangerous.
The country literally cannot get vaccines fast enough to roll out to the population. Astra Zenica, which Australia has millions of extra doses of, has only been recommended for use in over 60s due to blood clotting risks. We do not have enough alternative vaccines (Pfizer) to put into the arms of those under 60.
While I can understand that in comparison to the rest of the world, Australia has faired comparably well, we are poised on a knife edge between harsh and costly restrictions that save lives and just "letting it rip", and seeing the same brutal results that occurred in the US, India and the UK (among other places).
Without more of the population vaccinated, we don't have any other options.
