Queensland recorded three new cases of COVID-19 on Saturday, Deputy Premier Steven Miles announced.
He said three of the two new cases were girls aged between 0-9.
The two young girls are in quarantine, and are linked to the Brisbane Youth Detention Centre cluster.
The third new case is a man in his 20s also linked to a known outbreak, Mr Miles said.
The state now has 31 active cases.
Queensland’s Premier Annastacia Palaszczuk said the new cases had already been traced by the state’s health department.
“Today’s new cases are all contacts of previously confirmed cases and are in quarantine,” she said.
It follows the state recording two new cases on Friday, zero on Thursday and eight on Wednesday.
Wednesday was one of the largest single-day jumps in the state in weeks, with three linked to an outbreak at Ipswich Hospital, and five from one family linked to an outbreak at the Queensland Correctional Services Academy.
But since then, the numbers have trended down for the rest of the week.
