As Australia battles Omicron cases, states have introduced regular RAT testing twice a week for all students and staff.

“There are a lot of variables to consider.”

The introduction of the tests aims to continue to let children come to school and Mr Griffin said, “I think the use of rapid antigen testings is a potentially useful tool”.

“The more cases that around, then the more this could benefit.”
