Comment: After reading the article sounds like 111 new cases, but most were within family groups.
This sentence caught my attention:
"There are 75 people in hospital in NSW with Covid, including 18 in intensive care, and six needing ventilation"
OK, we need more information here such as average age, commobidities, etc. If these are all people in their 80's and 90's it makes no sense to do this extreme lock down to all of society.
