Seven COVID-19 cases have been recorded at a childcare centre in Melbourne's north, and will likely remain closed until late next week.
A staff member at Only About Children's Coonans Hill campus tested positive last week, with six new infections reported since.
It's unclear how many cases are children and how many are teachers.
Chief executive Anna Learmonth, in a letter seen by The Age and The Sydney Morning Herald, wrote that six of the cases were associated with the 0-two age rooms and one in the "Broad Beans" room.
Ms Learmonth said the centre was continuing to work with the Department of Health and Human Services in appropriate cleaning of the campus.
"In the next few days, an additional clean will involve the removal, cleaning and storage of all books, toys, paperwork, equipment and resources off premises," she wrote.
"Due to cleaning and self-isolation requirements, we will not be reopening this week or Monday 20 July. Our best estimate at this stage is towards the end of next week but we will keep you updated. Reopening is dependent on DHHS sign off, so timing remains fluid."
