An order for all Victorian teachers and childcare workers to get vaccinated against COVID-19 has been backed by the sector's unions and the state's peak Catholic schools body.
Education Minister James Merlino on Wednesday announced all staff at government and independent schools and all early childhood settings will need to have their first jab by October 18, or have a booking within a week of that date.
They will need to be fully vaccinated by November 29, unless they have a legitimate medical exemption.
The Catholic Education Commission of Victoria says it will also make the COVID-19 vaccine mandatory for teachers and staff in its 498 primary and secondary schools, sticking to the same timelines.
All government school staff will be entitled to half a day of paid time off to get vaccinated.
"Children under 12 do not have access to a vaccine, so we've got to protect our kids, both from contracting the virus and also transmitting the virus when they go home to their families," Mr Merlino told reporters.
"The best way to do that is to ensure that people who work with our children in early childhood, in care settings, in our schools, that they are all required to be vaccinated."
He said priority access would not be given to staff to receive a vaccine as there was "plenty of capacity" at the state-run hubs, pharmacies and GPs, while a recent survey of 33,000 teachers found 75 per cent were already fully vaccinated.
The Australian Education Union and Independent Education Union as well as the Early Learning Association of Australia welcomed the announcement.
AEU Victorian branch president Meredith Peace said the union has taken "every opportunity since vaccinations became available to encourage our members to get a COVID-19 vaccination as soon as they were eligible".
"The union's position continues to be that our members and the community should follow the public health advice in relation to COVID-19 safety measures, vaccination requirements and the safe return to on-site learning," she said in a statement.
IEU general secretary Deb James said the "fastest, safest way out of the pandemic remains for us to get vaccinated".
"Overwhelmingly, our members support vaccination as the most important tool to get schools back to normal," she said.
Mr Merlino also announced the government will spend $190 million to ensure schools are properly ventilated by the start of term four, in what he described as an "Australian-first unprecedented, massive investment".
This includes signing a contract with South Korean tech company Samsung to deliver 51,000 air purification devices to every government and low-fee independent school in the state.
Mr Merlino said the devices, which will begin arriving in the state from next week, will be placed in high-risk settings such as sick bays, canteens, staff rooms and music rooms.
Some $60 million will be spent on installing shade sails at 2149 schools to create more outdoor learning space, while a small trial of home antigen testing with students and their families will explore their feasibility.
A Ventilation Technical Advisory Panel will also be established to undertake further risk assessments of other environments including early childhood settings and youth justice facilities.
Year 12 students in Melbourne are going back to class on October 6 and a staggered return of other years will follow, starting with prep to Year 2s on October 18.
Opposition Leader Matthew Guy supported the state government's plan.
"We just want our kids back in school," he said.
