A new scientific paper has delivered a reality check for people hoping to be freed from their face masks when Australia reaches its 80 percent COVID-19 vaccination target.

The new research suggests that states should move away from aiming to achieve zero daily cases of COVID-19, saying that the goal for zero cases is unrealistic. 

Epidemiologist Catherine Bennett says easing restrictions should not be used as a reward and that some restrictions will be in place until the first half of 2022.
