Ms Palaszczuk thanked Queenslanders for their efforts but has warned she still holds grave concerns about the worsening outbreaks in NSW and Victoria.
She said Queensland's vaccination rollout will be ramped up in a bid to stay ahead of a virus leak from the southern states.
Health authorities will continue to prioritise food distribution workers and meat workers as Queensland receives more doses from the Commonwealth.
Health Minister Yvette D'Ath said Queensland hit a milestone in its vaccine rollout, with 112,397 people vaccinated in state clinics in the last seven days.
The First Nations clinics at Caboolture and Redcliffe saw 221 people vaccinated.
