The unvaccinated have only 3 reasons to leave home: essential shopping, medical treatment or care giving.

Unvaccinated Australians in the Northern Territory have been put under a new lockdown during which they won't be allowed to go outside to exercise or travel to work.

Yes, really.

The onerous new measures were announced by NT Chief Minister Michael Gunner in response to the detection of 256 new cases of COVID-19, including 27 cases of community transmission.

"The fully vaccinated can continue as they were. For people who are not vaccinated, lockdown rules will apply to everyone aged 16 and above," Mr Gunner said.
