Austria has imposed a lockdown on people who are not vaccinated, in a bid to lift the country's vaccination rate from 65 per cent.
Unvaccinated citizens will only be permitted to leave their homes to shop for essential needs, go to work or visit a doctor. They will also be allowed to go outside for fresh air at any time for the benefit of their physical and mental health.
There will be spot checks to ensure compliance, with violations punishable by fines of up to 1,450 euros (A$2,200 dollars).
COVID-19 figures have been climbing in Austria. Authorities registered more than 11,552 cases on Sunday, and the seven-day incidence per 100,000 people climbed to nearly 850.
The lockdown measures will be in force for an initial period of 10 days. Chancellor Alexander Schallenberg said individual states were free to put even stricter rules in place.
The capital Vienna has already announced it will put in additional rules to require a PCR test from vaccinated and recovered people going to restaurants at night and at all events attended by more than 25 people.
It is hoped the lockdown will encourage vaccination. Previous tightening up of rules has already seen a jump in the number of people getting jabs. However the percentage of the Austrian population currently vaccinated is still 65 per cent.
The Austrian government is also considering a general night-time curfew from 10 pm. A decision on the move, which would apply to everyone, will come on Wednesday, Austrian Health Minister Wolfgang Mueckstein told a radio program.
