Queensland has recorded two new locally-acquired cases linked to St Thomas More College.
Both students are in home quarantine and Chief Health Officer Jeannette Young says she is "fairly confident that cluster is in hand due" to the response of families, the school and the Metro South Hospital and Health Service.
There were two other cases in hotel quarantine.
On Friday, St Thomas More College was closed and families forced into quarantine after a 13-year-old student was infected with Delta.
Both new cases are 15, one is a male, one a female from two different households.
Premier Annastacia Palaszczuk praised the school students, staff and families for quarantining.
“We are thanking you for doing the right thing for Queensland," Ms Palaszczuk says.
"Please continue to do the right thing because you are helping Queensland."
