As it happened: Dominic Perrottet becomes next NSW premier as state records 608 new COVID-19 cases, seven deaths; Victoria sets national daily record with 1763 new cases, four deaths

That's all for today. Thanks for reading. Here's a summary of the day's headlines:

• Dominic Perrottet is the 46th Premier of NSW after he was sworn in this afternoon. Mr Perrottet won this morning's leadership ballot 39-5 to become the new Liberal Party leader following the resignation of Gladys Berejiklian on Friday. He is the state's youngest premier at age 39 and has framed his leadership as being the premier for families.
• Victoria recorded a new national high of 1763 cases of COVID-19 but Premier Daniel Andrews reaffirmed the state's road map to exit lockdown and open back up in line with the vaccination targets. Thirty-nine prisoners and 15 staff at five jails have been infected.
• Qantas boss Alan Joyce says home quarantine should be a short-lived solution to opening Australia’s international border, and the country should lift all isolation requirements as soon as possible to restart tourism and business travel. The airline will place a multibillion-dollar order for more than 100 new jets to replace its ageing domestic fleet of aircraft.
• After leaving interest rates at record-low levels, the Reserve Bank is sticking by its belief that rates will not rise until at least 2024 despite an avalanche of cheap money being pumped into the economy and growing expectations the national jobs market will recover quickly from COVID-19 lockdowns.

Melbourne today claimed the title of world’s most locked-down city, passing Buenos Aires’ record of 245 days.

The fatigued city also marked another record: 1763 new cases and another four deaths, the highest daily number of cases in any state since the virus arrived in Australia last year.

By the time restrictions lift – if they lift on the target date of October 26 – Melbourne will have spent about 267 days in lockdown.

Why aren’t our extended lockdowns driving case numbers down? And how much worse would it be if Melbourne wasn’t in a strict lockdown?

Today on Please Explain, The Age’s state political reporter Sumeyya Ilanbey joins Bianca Hall to discuss the city’s lockdown – and the pathway out.

Victoria administered 96,337 doses of COVID-19 vaccine yesterday, more than all the other state and territories combined.

It could be partly explained by the fact NSW and Queensland had public holidays, and also that NSW is running out of vaccine candidates given its higher coverage rates.

Among yesterday's numbers was a record number of Victorians who received their second vaccine dose

Health department data shows a total of 51,378 people aged 16 and over statewide became fully vaccinated on Monday, breaking the state's previous record by more than 5000.

Or, to put it another way, 53.57 per cent of Victorians aged 16 and over have received their second vaccine dose, up from 52.62 per cent yesterday.

Now that the time between Pfizer vaccine shots has been reduced from six weeks to three weeks at state government vaccine hubs, Victoria has reached the stage where more second doses than first doses are consistently being administered each day.

Dominic Perrottet is officially the new premier of NSW after he was sworn in at a ceremony at Government House in Sydney this afternoon.

His deputy is Stuart Ayres and the new treasurer is Matt Kean. (Note that Mr Ayres is deputy of the Liberal party, not the deputy premier. That title is held by the leader of the Nationals and a vote for that position will be held tomorrow after John Barilaro also resigned.)

Below are some photos from the ceremony. For more details on how the day unfolded, you can read this separate live blog we're running on the NSW leadership vote.

Dozens of people have caught COVID-19 from the CFMEU Victorian office cluster, triggering an angry response from the union's state secretary John Setka.

Seven people who work at the office, which was targeted by a mix of protesters angry with vaccine mandates and lockdowns last month, have now tested positive for the coronavirus along with dozens of their family members.

Mr Setka laid the blame at the feet of the protesters.

“These protesters are just selfish idiots with absolutely no care for anyone other than themselves," Mr Setka said in a statement.

"They have caused enormous stress and heartache for members families’ who were just doing their job on the day of the protest.

“While we welcome construction opening back up to 25 per cent today, these members won’t be going back to work and along with their families will be in quarantine for two weeks with the added stress of so many family members being very sick and some hospitalised."
