Queensland's Covid outbreak grew by 19 cases on Wednesday, Deputy Premier Steve Miles announced at the state's daily update.
Sixteen cases were locally-acquired and linked to the Indooroopilly State High School Delta cluster.
Four cases are linked to Ironside state school including one teacher, two cases to Indooroopilly state High School, one case is linked to Brisbane Boys Grammar and nine cases which are close contacts or family members of cases already identified in the cluster.
'That brings this outbreak to 63 genomically linked cases meaning that in less than a week, this has become our biggest outbreak since the first wave last year,' Mr Miles said.

'Maybe just stay home because you can only move this virus around if the person moves around.'

She said the Cairns pilot had likely acquired the Delta virus while working and despite being fully vaccinated with Pfizer.
'It's highly likely he's acquired this infection while he's been about his work piloting one of those ships,' Dr Young said.
'His family members who live in the same household as him, his partner and child, are negative, but he did take his child to a child care centre so that's why the child care centre his child attends has been closed while they clean it and assess the risk there.'
The number of close contact exposure sites is approaching 150, with recent additions including Kmart, McDonalds and Aldi in Indooroopilly, a swim school in St Lucia and a netball court in Graceville, as well as a site on the Gold Coast.
