Australia reached on Saturday a full inoculation rate of 80% of those aged 16 and older, which Prime Minister Scott Morrison called a "magnificent milestone" on the path to becoming one of the world's most vaccinated countries against COVID-19.

Once a champion of a "COVID-zero" strategy to manage the pandemic, the country of 25 million has moved toward living with the virus through extensive vaccinations, as the delta variant has proven too infectious to suppress.

"Another, magnificent milestone, Australia," Morrison said in a video post on Facebook. "That's four out of five, how good is that? This has been a true Australian national effort."
