After months of remaining closed to Victorian residents, NSW will drop its border restrictions in just three weeks.

On Wednesday NSW Premier Gladys Berejiklian revealed the border would open on November 23.

That is about a month after her Victorian counterpart Daniel Andrews put an end to Melbourne’s tough stage 4 lockdown.

The southern state has since recorded five consecutive days of zero cases while NSW announced three new local cases on Wednesday.

“As long as a state can demonstrate it can get on top of cases, we are OK with that,” Ms Berejiklian told reporters.

 “I’m confident other states will have that capacity … they’ve certainly had enough time to prepare for this.”

Ms Berejiklian acknowledged there was a risk with opening the border, but given recent figures, it appears Victoria has gone down the path of elimination and she has confidence the Andrews government has the right systems in place.

The decision came after “careful consideration” and conversations with Mr Andrews and Scott Morrison, Ms Berejiklian said.

The move will set NSW apart from the rest of Australia as the only state to welcome residents from all other states and territories as well as citizens from New Zealand.

Victoria never closed its borders but travellers were discouraged from going there because they’d be forced into mandatory quarantine after returning to their home state.

“With that comes some level or risk and we accept that, but it’s a cautious risk and a calculated risk,” she said.

Ms Berejiklian’s stance is a stark contrast to her Queensland counterpart Annastacia Palaszczuk, who has so far refused to open the Queensland border to Sydneysiders.

Last week Ms Berejiklian told reporters making a decision on opening the border to Victoria could only come after the state had been out of lockdown for at least two weeks in order to gauge how opening up would influence coronavirus numbers.

“Now that Victoria is down to zero or a handful of community transmissions a day, that gives us pause to reflect on when that two-week period starts for us, and of course we'll base that on health advice,” she said on Monday.

“But I certainly wanted to give the signal to the people of NSW that we‘re talking weeks not months in terms of when the Victorian border may come down, but that again is based on health advice.

 “I think it is important to allow people to plan ahead. It's important for our airline sector, it’s important for people who rely on hospitality and tourism to consider what the future may hold.

“That's why, without pre-empting any future decisions, it could be weeks not months in terms of the NSW-Victoria border opening.”

The border between NSW and Victoria closed for the first time in a century on July 8.

Another nine cases of COVID-19 were announced in NSW on Wednesday, including three local cases.

Victoria hasn’t recorded a case for five days.

Meanwhile, Ms Palaszczuk rubbished suggestions the NSW-Victoria border reopening should serve as a hurry along for the Sunshine State to loosen its restrictions further.

“I’ve said all along we will review those decisions at the end of the month,” she told reporters on the Sunshine Coast, insisting she will continue to defer to the state’s chief health officer Dr Jeannette Young.

“What is encouraging from Victoria is the really low cases.

“But, of course, they’re coming out of lockdown so we’re going to be looking very carefully over the course of November to see how they go.

“A lot can happen in a month, so people need to have a bit of caution. Let’s just take it one step at a time and let’s just see how that community transmission transpires as Victoria comes out of lockdown.”

Ms Palaszczuk congratulated Victorians on the “tremendous” effort to bring new coronavirus case numbers back down to zero.

“A lot of Victorians have made a lot of sacrifices over the period of the lockdown and Australia is very thankful for that hard work,” she said.
