Fiji will ease Covid-19 restrictions and announce its reopening for international travel after the country hit a vaccination milestone.

Changes to the country's virus restrictions would be announced on Sunday afternoon after 80 per cent of the adult population received both doses of a Covid-19 vaccine, Prime Minister Frank Bainimarama said.

“A full three weeks ahead of schedule! I'm grateful to everyone who's rolled up their sleeves to help make Fiji safe,” Bainimarama said in a tweet.

“I'll announce the easing of Covid restrictions at home and our plan to reopen Fiji to the world.”
