Nearly 85% of Australians aged 16 and above had been fully vaccinated against the coronavirus as of Friday (November 19).
While nationwide vaccinations are voluntary, states and territories have mandated vaccinations for many occupations and barred the unvaccinated from activities such as dining out and concerts.
Several thousand anti-vaccination protesters marched through downtown Sydney and Melbourne, with no immediate reports of unruly behaviour.
The anti-vaccination rallies have continued for weeks in Australia, becoming occasionally violent and attracting loose groups of regular citizens, as well as far-right and conspiracy theory supporters.
The anti-vaccination movement, however, remains small, with polls showing nationwide opposition in the single digits.
