A hard lockdown in the City of Logan has been extended until at least Sunday.
All non-essential businesses have been told to close, and people asked to work from home where possible.
The extension was announced after 13 new cases on Monday, most related to a case of the Delta strain at Ironside School.
There were more than 20,000 Covid tests conducted on Sunday, and the government has asked people to double that number as more clinics opened mid-week.
Treasurer and member for Woodridge Cameron Dick said businesses would be able to apply for grants of up to $5000 to compensate for inevitable losses.
Premier Annastacia Palaszczuk said strong measures announced at the beginning of the 8-day lockdown go further than previous lockdowns because the Delta strain is more dangerous.
“We’ve seen the evidence, both in Queensland and interstate,” the Premier said.
“We must go hard and go fast.
“I know this will impact on many families but there is no alternative.”
Minister for Health and Ambulance Services Yvette D’Ath urged Queenslanders to abide by the lockdown and continue to wear their masks.
“Masks are a vitally important line of defence,” the Minister said.
“I know lockdowns are not pleasant, but a short circuit breaker is better than the alternative.
“The residents of NSW are seeing the tragic consequences of the virus being uncontained.”
Chief health advisor Jeannette Young said:
“We need all people in the affected areas to stay home unless it’s absolutely essential to leave home for one of the permitted reasons.
“If you do leave your home during the lockdown period, you should remain within 10km of your home wherever possible.
“As always, at the earliest sign of even the mildest symptoms, get tested and self-isolate until you get your result.
“Keep practicing good hand hygiene and social distancing.
“If you have an appointment to get vaccinated, keep it. This applies to everyone, but especially the over 60s. If you haven’t already, book in for your AstraZeneca jab with your GP. Don’t wait until there is a significant outbreak – act now.”
