From September 28, Melbourne will move to a second stage if the city reaches an average daily case rate of 30-50 cases over the previous 14 days.
If the city does achieve this, it will still have a night-time curfew.
Residents will still have to remain within 5 kilometres of their homes and will only be allowed to leave home for the permitted four reasons.
Outdoor public gatherings of up to five people from two households will be allowed, with infants under the age of one not included in this number.
