ACT Chief Minister Andrew Barr is hoping the territory will reach 90 to 95 per cent full vaccinations by Christmas.
He believes the country will be tracking closer to the 80 per cent mark by that time.
Barr says the delta variant is very difficult to contain and that will put pressure on the health system around the country.
“Other parts of Australia have been able to help the states and territories that have cases,” he says.
“For the ACT, that has meant that both Western Australia and Tasmania have assisted us in things like contact tracing. That has been really, really useful.
“The issue we’re going to face if, when, the entire country opens up and COVID is everywhere, is everyone will have to deal with their local situation.
“It is unlikely that there will be the capacity for another part of the country to come to the rescue because they’ll have their local issues to deal with.”
Barr says the greatest risk will come at 70 per cent full vaccinations because 30 per cent of the population will be without a jab.
