Ventilation actions on COVID-19 were part of Europe’s response to the pandemic in 2020, but Australia has only just started to accept the need for improved ventilation as it was very late to the risks of aerosol transmission.

As vaccinated workers return to workplaces in many of Australia’s urban centres, employers will need to assess their occupational health and safety (OHS) duties in new ways, and ventilation will be a significant challenge.
