MELBOURNE (REUTERS) - Melbourne, Australia's second-biggest city, began its first weekend out of the world's longest string of Covid-19 lockdowns with spontaneous street parties, live music and packed pubs, bars and restaurants.

Home to about five million people, Melbourne endured 262 days, or nearly nine months, of restrictions during six lockdowns since March 2020, longer than the 234-day continuous lockdown in Buenos Aires.

Despite rain on Saturday (Oct 23) morning, people queued for barbers and breakfast restaurants, all of which are open only to the fully vaccinated.

While most retail outlets remained closed, authorities said further easing will come once 80 per cent of Victorians are fully inoculated, estimated by next weekend.

"Let's not slack off, let's increase the pace as we get to the 80 per cent milestone - but also the 90 per cent vaccination milestone," Mr Jeroen Weimar, Victoria's Covid-19 response commander, said on Saturday.

While small but violent anti-vaccinations protests have taken place in Melbourne and other cities this year, Australians overwhelmingly support vaccinations, with polls showing the percentage decisively opposed in single digits.

Nearly 72 per cent of adults in Australia are now fully vaccinated and nearly 87 per cent have received one shot.

According to a national strategy, lockdowns will be unlikely once 80 per cent of Australians are fully inoculated.

Sydney, Australia's largest city, celebrated its reopening two weeks ago, after reaching the vaccination threshold of 70 per cent. On Saturday, New South Wales state, of which Sydney is the c...
