Authorities say Covid-19 restrictions will be eased further in Sydney from Monday as Australia's largest city looks set to exit a nearly four-month lockdown after hitting its 70 per cent full vaccination target, Reuters reports.

Fully vaccinated people in New South Wales state will be able to leave their homes for any reason including visiting pubs, retail stores, cinemas and gyms, which will reopen under strict social distancing rules.

The number of vaccinated visitors allowed to gather in a home will double to 10, while the limit on vaccinated people at weddings and funerals will be raised to 100. Nightclubs can partially reopen to vaccinated people once inoculations reach 80pc, earlier than previously planned, and masks will not be mandatory in offices.

The state will use a vaccination-passport system to ensure those who have not been fully inoculated remain under strict stay-home orders until December 1.
