"At a population level, the focus now is on damping down transmission and minimising harm much more than identifying and interrupting every single case and transmission chain."
Currently, there are 179413 active Covid-19 cases across the country.
Given the evolving situation with Covid-19, Baker believes the isolation experience should be as "supportive as possible".
"I think in some ways the dynamic has shifted to make that [isolation] as sustainable as possible for people and we know exercise is particularly good, especially if you are stuck at home.
"If you are outside the risk of transmitting to other people is low right away, as long as you are taking sensible precautions."
During times of isolation, he said it was important to encourage people to exercise.
"We want to make home isolation as comfortable and health-promoting as possible."
When people isolating go out to exercise, Baker said the "three C's of transmission" should be considered, those being confined, crowded and close.
Baker said if people take suitable precautions then there should be no issue with exercising outside.
However, he said if someone knows they will be in an area with others who are not in the same household Baker recommends the use of a face mask.
