SYDNEY, AUSTRALIA - OCTOBER 06: Joggers move along the Milsons Point boardwalk at sunrise on October 06, 2021 in Sydney, Australia. The NSW government has outlined a roadmap for easing COVID-19 restrictions once the state reaches its 70% double vaccination target - which is expected to be achieved this week. From Monday 11 October restrictions will ease for those who are fully vaccinated, with up to five visitors permitted in a home, and up to 20 people allowed to gather outdoors. Gyms, indoor recreation and sporting facilities able to reopen while retail and hospitality can also reopen subject to density limits. Schools will begin to reopen from 18 October. The 5km rule will be lifted, but residents of Greater Sydney will not be allowed to travel into regional areas until the state reaches 80% double dose vaccinations.
