Queensland Deputy Premier Steven Miles on Monday said the border could remained closed to NSW even when vaccination rates reached 80 per cent.

NSW recorded 818 new Covid-19 infections overnight while Victoria had 71, ACT 16 and Queensland one.

Mr Miles, who in February filmed himself tearing up a $3om hotel quarantine bill Queensland owed NSW, said the Doherty Institute’s vaccine modelling was endorsed “before the NSW outbreak” and might not be honoured.

Western Australian Premier Mark McGowan, who accused NSW of “failing” in its handling of the Delta outbreak, also suggested he would keep a hard border with NSW even as vaccination rates increased.

National cabinet has based a four-stage plan for easing national restrictions on the Doherty Institute’s report.

Ms Berejiklian cautioned other states that the highly infectious Delta strain would hit their states too.

“In NSW, having a relatively good 18 months compared to the rest of the world, we are (now) facing what every other jurisdiction has faced and that’s confronting,” Ms Berejiklian said.

“But that's OK because every state in Australia is going to have to go through this eventually.

“Eventually, borders are going to have to come down and it’s up to how each premier responds to the national plan.

“But whenever the borders come down, Delta is going to be part of (life).”

Ms Berejiklian also hit out at other premiers for failing to recognise that NSW accepts the majority of the 3000 (capped) international arrivals each week.

“NSW is the … most densely populated state in Australia and we have to accept that the challenges that we face here are very different from what happens in Tasmania and even WA, which is a more isolated state,” she said.

“(But) it doesn't mean that we (shouldn’t) all allow our citizens to live as safely and as freely as possible (once vaccinations rates were high).”
