‘Poor infection practice’
Meanwhile, new research shows more than two-thirds of Victorian healthcare workers were likely to have caught COVID-19 at work during the state's devastating second wave.
Under the strategy, every health service in Victoria will introduce "personal protective equipment spotters" and study potential aerosol hotspots.
They will also trial "fit testing" for high-risk staff, to make sure PPE is being worn properly.
The new detailed research shows at least 69 per cent of healthcare infections across the second wave have likely happened in workplaces.
In the first wave, only 22 per cent of infected healthcare workers were believed to have caught coronavirus on the job.
"Poor infection practice has probably been the main driver of infection," Victorian chief medical officer Andrew Wilson told reporters on Tuesday.
"There have also been issues about aged care workers moving between different facilities as a key driver of infection."
Other leading causes of infection in the sector were shared spaces, including contact in tea and break rooms, substandard PPE use and ageing ventilation systems.
"There have been outbreaks related to how it (PPE) was stored," Mr Wilson said.
"There have been outbreaks (linked) to even residents potentially contaminating the PPE."
Active infections among healthcare workers, in aged care and disability facilities are all decreasing.
But Health Minister Jenny Mikakos flagged more action would be undertaken to slow the spread in health settings.
"If the tea room, for example, is just too small for people to be able to have a meal safely, then we will be establishing marquees and other facilities with appropriate heating to make sure healthcare workers can have access to those basic amenities," she said.
Metropolitan Melbourne residents are subject to Stage 4 restrictions and must comply with a curfew between the hours of 8pm and 5am. During the curfew, people in Melbourne can only leave their house for work, and essential health, care or safety reasons.
Between 5am and 8pm, people in Melbourne can leave the home for exercise, to shop for necessary goods and services, for work, for health care, or to care for a sick or elderly relative.
All Victorians must wear a face covering when they leave home, no matter where they live.
People in Australia must stay at least 1.5 metres away from others. Check your state’s restrictions on gathering limits.
